FW 1.5 Challenge: Maintain optimum sustainable finfish fisheries 80% Full
Populations of some finfish have been stressed or reduced due to a variety of factors, including natu­ral cycles, availability of food (including forage fish and viability of the benthic community), abun­dance of habitat (sedimentation), over fishing, and water quality degradation, including light attenu­ation. To better manage the coastal bays ecosystem there is a need to understand the differences in natural environmental changes and those changes caused by man.
The forage index (species richness index of juvenile menhaden, spot, Atlantic silverside and bay anchovy) has decreased in the coastal bays since 1989. The exact reason for this decrease is not known but is possibly related to decreases in spot. There are many possible factors impacting forage species, including natural causes, personal water craft, poor water quality, over-harvesting, lack of food, predation, decrease of suitable habitat, and land use practices. The abundance of these species may be used as a long-term indicator for monitoring the fish community structure and overall health of the coastal bays. The most abundant species in coastal bay samples since the 1970's are spot, bay anchovy, Atlantic silversides, and Atlantic menhaden. Delaware has seen a decrease in menhaden, spot, and bay anchovy.
The abundance of summer flounder, weakfish, and Atlantic croaker have been on an upward trend since the early 1990s. These trends are most likely due to strict recovery programs which have been mandated by the Atlantic States Marine Fisheries Commission and enacted by the states, including Maryland. Menhaden as well as spot reproduction is down throughout their whole range. Anchovy and silversides reproduce here so there might be something in the coastal bays affecting their repro­duction and abundance (predation).
The community's economy is primarily based on tourism and the ability of tourists to enjoy the bays. Therefore, commercial catch vs. recreational pressure and economics needs to be analyzed and used in determining catch allotments. There is a lack of information on the effects that recreational fishing has on fish population.
There also is a lack of information on habitat requirements for finfish. Poor water quality frequently decreases available fish habitat, thus contributing to decreasing fish numbers. Low oxygen levels are especially harmful to bay life and are a standard indicator of degraded water quality. There are cur­rently several monitoring efforts in the coastal bays (MCBP volunteer water quality monitoring, DNR monitoring, and the NFS water quality monitoring) but the conclusions from the studies have not been determined.
Solution: Develop a finfish management plan that investigates stock management practices, habitat improvement (especially for flounder), and education opportunities that protect and restore sustainable finfish populations in the coastal bays, while enhancing fishery-dependent economies.
Measure of success: establishment of plan for achieving monitoring & maintaining optimal sustainable finfish fisheries populations. [determined to be infeasible as finfish are managed coast wide by ASMFC] What is feasible for the Coastal Bays?
The Coastal Bays Fisheries Trawl & Seine Survey began in 1972. In 1989 the survey was altered to follow a standardized protocol with further refinement in database and verification procedures in more recent years. Annual reports are available detailing catch and abundance as well as Seafood Dealer Catch monitoring, Volunteer Flounder Survey information and special projects findings such as the SAV drop net program. In 2002, a cooperative angler flounder survey began through the MD Saltwater Sportfishing Assoc., and local anglers with the goal of collecting and assessing the data gathered to promote better fishing techniques and legislation to benefit both the fish and the fishermen. See Investigation of Maryland’s Coastal Bays & Atlantic Ocean Fishfish Stocks 2007-2011 (DNR)
Actions:

  1. DNR, with advice from the Coastal Bays Fishery Advisory Board, will investigate but is not limited to the following suggested stock management practices. Modify – needs revision per DNR input on scope of work, available resources & jurisdiction.

  1. Establish entry, gear, and limit restrictions on commercial sector.

  2. Determine recreational catch. Investigate establishing a saltwater fishing license with proceeds being used for research. License should have several categories like 5-day, month, season, etc. This would give a data base of names and addresses for conducting surveys.

  3. Re-examine recreational and commercial catch allocation issues.

  4. Re-examine size limits including consistency with surrounding states.

  5. Obtain MD Coastal Bays catch data (commercial vs. recreational).

  6. Investigate by catch issue for gill nets. Consider an "attend-a-net" policy.

  7. Further investigate the forage index (natural, personal water craft, over-harvesting, not enough food, birds, lack of habitat). Need to address the issue of forage fish and maintaining quality of their habitat.

  8. Need to determine what each finfish needs to live and eat.

  1. DNR will investigate but is not limited to the following habitat improvement recommendations: Modify

  1. Improve water quality by reducing sedimentation from agriculture, development, and dredging (See Water Quality section).

  2. Collate information obtained from the volunteer monitoring program, DNR monitoring, and the NFS monitoring efforts and release results to the public (See Monitoring Plan).

  3. Investigate the influence of jet ski noise on scaring fish away. Contact Florida on their studies on jet skis vs. fish (See Recreation and Navigation).

  4. Restore and protect finfish habitat.

  5. Investigate effects of habitat loss, including wetlands, and sediment contaminants from uncontrolled growth. Also investigate algae beds as potential habitat.

  6. Investigate forage fish habitat requirements.

  7. Adopt a reduced speed limit to reduce the impacts of boat operation in shallow water, reduce prop scarring, and decrease the impact of wave action (See Recreation and Navigation).

  8. Investigate and create, if needed, the following resource protection areas.

      1. Expanded no trawl zone near inlet that is consistent with neighboring states.

      2. Areas where all boating activity must stay clear.

  9. Separate natural environmental changes brought about by the aging of the system and deal with only those things that man can affect (sedimentation is natural, that the East Coast is sinking, and that sea level is rising).

  1. MCBP and DNR will encourage responsible fishing practices such as catch-and-release, innovative hook designs, and crab traps with terrapin exclusion devices. Keep – educational effort

  2. DNR and MDE will investigate the utility of creating artificial reefs in the coastal bays to enhance tautog and seabass populations. If feasible, DNR will develop artificial reefs (e.g., creation of hard bottom habitat by planting shells, stone or other substrate). Modify to specify where reefs could be beneficial – most areas of the bays are too shallow.

  3. MCBP and DNR will educate fishermen on size and creel limits. Keep

  4. DNR will:

  1. Review state and federal data and determine appropriate biological reference points for each important commercial and recreational species of concern. Keep as an educational effort, based upon ASMFC/MAFMC guidance

  2. Implement appropriate control measures if sustainable yields are exceeded or other problems are identified within a fishery. Supplement – monitor the sustainable yields over time as a measure of ecosystem management.


Expected Benefits:

  • a Fishery Management Plan, unique to the coastal bays, will protect the resource and balance commercial fishing and environmental interests.

FW 1.6 Challenge: Seagrass protection and expansion 95% Full
Seagrasses are valuable habitat for fish, shellfish and other wildlife such as waterfowl. Seagrasses are considered essential habitat for summer flounder and scallops and critical habitat for blue crabs. Although the distribution of seagrass has been increasing in the coastal bays, many factors, such as water quality and bottom type, limit it from expanding to its fullest potential. Other factors, like hydraulic clam dredging and prop scarring from boats, can decrease the density within a bed.
Currently, photo interpretation may not be sufficient to document the location and distribution of all seagrasses due to the time of the aerial flights (early May), depths of beds, density of beds, and limits of photography equipment.
Solution: Identify, protect, enhance, and promote natural recovery of seagrass beds in order to improve water quality and fish habitat.
Measure of success: Increase in acres of seagrass, establishment of seagrass protection areas.

Annual monitoring of sea grass acreage is determined by aerial flights & interpretation by the Virginia Institute of Marine Sciences. Data is available from 1986-2009. A goal of 20,070 acres has been developed based on suitable sediment types and water depth. Goal attainment is evaluated using current 3 year averages.


NOTE: SAV abundance is one of the annual Report Card indicators of Coastal Bay health.

    2. Researching seagrass recovery time. Done

    3. Investigating use of buoys to mark beds, SAV setbacks, depth restrictions, GPS equipment to identify delineate SAV boundaries [HC-FMP 6.2.1] and education as tools to protect beds from damage. Keep

    4. 6.2.1b Continue to foster the legislative support to make recommended changes in the SAV law which would benefit all stakeholder groups by making the delineation and enforcement process more manageable, the closure areas consistent over a longer period of time, and Implement and enforce necessary regulations to protect SAV from clam dredging including the prohibition of hydraulic dredging within SAV beds [6.2.1] Done

      1. 6.2.1a The MCBP Fishery Advisory Committee shall become the local group to develop and provide recommendations to DNR regarding the delineation of SAV closure areas to harvesting by hydraulic clam dredging.

      2. Blue Crab-FMP 5.1.3 DNR will continue to identify SAV species needing protection activities needing restrictions.

  1. MCBP will explore feasibility of an SAV sanctuary (including needed legislation/regulations), identify species needing protection and activities needing restriction. Modify to reflect the current need to respect Assateague Island boundaries.

  2. MCBP will expand surveys/citizens monitoring to groundtruth species composition and determine accuracy of photo interpretive maps. Supplemental – remove this as a specific action but keep it as a monitoring indicator.

  3. DNR and NRCS will develop habitat requirements for the growth of seagrasses in the coastal bays:

  1. DNR will develop water quality requirements for seagrasses (work with University of Delaware). Supplemental – keep as a monitoring indicator

  2. DNR will identify areas that are meeting the required water quality once water quality data is available (e.g., areas that have the greatest likelihood of SAV expansion). Keep- (quantifiable goal & annual report card indicator, TMDL goal)

  3. NRCS will compile data relating bay soil types to bottom communities and identify other variables having effects on seagrass establishment and maintenance. Done – completed by MGS

FW 1.7 Challenge: Improve water quality in dead end canals 58% Substantial
Dead-end canals are major storehouses of chemicals and other pollutants because of poor flushing. Studies have shown that dissolved oxygen (vital to sustain aquatic life) in dead-end canals was half that found in non-canal sites. Certain nutrients were twice as high in these canals (causing growth of algae). Pesticides and other toxic chemicals were also significantly higher in canals, and biotic communities in the sediment (important fish food) were profoundly degraded (95 percent consisted of pollution-tolerant worms instead of crabs, clams, mussels, shrimp and immature insects). Storm water runoff from adjacent land, bulkhead materials, boats, and maintenance dredging/canal con­struction all contribute to these impacts. Storm water carries nutrients, chemicals, sediment, and organic matter to the canals as a result of the adjacent land practices. Bulkhead materials also can contribute to the degradation of canals through the introduction of chemicals used to preserve bulk­head material. Boats contribute to the deteriorated conditions in the canals through motor and wake agitation of the sediments and from boat maintenance, including the use of anti-fouling paints. Maintenance dredging also re-exposes pollutants and accelerates their detrimental effects. The fact that canals are artificially dredged deeper than surrounding bay waters compounds water quality problems due to decreased flushing and stratification of the water.
Solution: Investigate options for environmental enhancement in dead-end canals.
Measure of success: Number of canals with stormwater retrofits, changes in canal maintenance practices, cessation of new end-end canals.
There are 64 canals in Ocean City; the longest is approximately 4,4oo linear feet. Most were created in the 60s and early 70s. Bulkheads were built in wetlands or in the water, then canals were dredged and the spoils were used to create land for development.
In 2008 the Town of Ocean City adopted an ordinance that allows the City to take over maintenance dredging of City Canals. A description of Town efforts and dredging plans is available at http://www.oceancitymd.gov/engineering/canal_dredging.html
Dead End Canal Workshop recommendations (2003)
Actions:

  1. Retrofit all drainage into canals. Options include installing stormwater management facilities and devices (especially systems containing tiles or ditches) and other methods to slow storm water flow. Alternative bulkhead materials should be promoted. Modify to include more partners (Wo. Co., Ocean Pines, private harbors)

  2. MCBP will target property owners along canals for education and implementation of best management practices for backyard management. Techniques such as proper fertilizer application, controlling or removing animal feces, stopping trash inputs (including removing cut grass, dead flowers and leaves from surrounding areas), limiting crop irrigation or lawn watering, and encouraging native species planting "BayScapes," etc. should be promoted. Keep – educational effort

  3. Interconnect canals to increase flushing (need to use 8 ft. diameter pipes). Modify to become a Worcester County action and to target appropriate communities

  4. The MCBP Navigation and Dredging Advisory Group (See Recreation and Navigation section) will develop canal maintenance dredging plans that recommend dredging only when absolutely necessary and that consider all habitat restoration potential. Modify to have OC and WC as co-leads, list as a funding need. Consolidate FW 1.7.4 and 1.7.7

    1. Determine who have jurisdiction and responsibility for which canals (OC, WC, OP).

    2. Investigate the feasibility of establishing a tax lagoon district for maintenance and improvements. Educate property owners in how to petition for the establishment of a district.

    3. Educate marine contractors to fill depressions with dredge spoils, grade canals on a slope to allow for natural tidal flushing and prevent sill deposits at canal opening.

    4. Determine if dredge spoils can be used to fill in deep holes created to fill marsh land in established neighborhoods.

    5. Coordinate efforts with NADAG’s Master Planning Guide (RN 2.1)

    6. Create a regional dredging database with pertinent information such as: volume of material requested or needed removed, character of material (grain size and composition) from dredge site, character of material required for deposition at receiving site, unusual site considerations (high fetch, high traffic, current scouring or erosion, etc), desired timeframe for project, is the permit application filed?, has a permit been acquired?, etc.

  5. Investigate alternatives for undeveloped canals Done

  6. MDE will continue to enforce their policy of not approving new dead-end canals. Supplemental – continue current policy

  7. Develop canal stormwater management plan requirements. Consolidate with FW 1.7.4

    1. Approach homeowner’s association meetings as a forum to increase public involvement.

    2. Direct road and roof runoff into swales and rain gardens where feasible.

    3. Reduce imperviousness around canals.

FW 1.8 Challenge: Reduce trash in the coastal bays 68% Substantial
Trash is one of the first indicators that most people associate with degraded water quality. Trash such as plastic bags, balloons, fishing line, cigarette butts, plywood in marshes, etc. can injure and kill fish, wildlife and other marine life.
Solution: Support "Trash-Free Bays" events and ideas that involve students and citizens to help keep the bays clean.
Measure of success: numbers of citizens involved in educational efforts, changes in rates of littering (or volume)

The International Coastal Cleanup has resulted in more than 11,000 pounds of trash removed from local beaches (2005-2008). The average amount each year is ~3,000 lbs. MCBP has held annual cleanups throughout the years as well. From 2010-2012, 3,578 volunteers have collected nearly 5,000 lbs. of trash.



Actions:

  1. MCBP will develop events to educate public on impacts of trash, including tributaries and bridge areas where the problem is most severe. Consolidate 1.8.1 and 1.8.2, track areas & lbs of trash over time as a social involvement indicator

  2. MCBP will support events such as: Adopt-A-Shoreline, Coast Day, canoe cleanups, roadside trash cleanups, teacher training, and field trips for classes. Consolidate with above action

  3. OC will improve trash management on beaches by placing lids on trash cans and emptying them more frequently where deemed necessary and feasible. Consolidate FW 1.8.3 and FW 1.8.4

  4. WC and MCBP will organize effort to clean up trash from dead-end canals. Consolidate with above action

  5. MCBP will educate public and organize events to pick up plywood and debris from abandoned duck blinds in marshes where plywood and boards smother marsh grasses. Keep. Make Newport Bay a focus for this effort.


Expected Benefits:

  • improved aesthetics and habitat quality

  • reduced costs for trash removal



FW 1.9 Challenge: Reduce loss of shoreline habitat 50% Moderate
Loss of shoreline habitat due to hard shoreline protection methods (e.g., bulkheading) is prevalent in the coastal bays. Because shoreline habitats are very important for many reasons (horseshoe crabs, waterfowl, birds, reptiles, water quality and clarity), alternative methods of shoreline protection that provide habitat should be encouraged where practical. According to scientific estimates, sea level is expected to rise by 6 to 37 inches by 2100. One effect of rising sea level will be landward migration of coastal wetlands as shorelines are eroded and low-lying areas inundated. Bulkheads and other shoreline armoring techniques that are used to halt erosion also prevent wetland systems and sandy/muddy beaches from migrating inland.
Solution: Protect and enhance natural shoreline in order to preserve habitat for fish and other bay life.
Measure of success: changes in conversion rates of natural shoreline habitat, miles of shoreline stabilized using environmentally friendly stabilization practices, miles of natural shoreline

The state 1984 Critical Area Law was expanded in 2004 to include the Coastal Bays watershed. Land within 1,000 feet of the mean high tide line or tidal wetlands were categorized as Intensively Developed Areas, Limited Developed Areas or Resource Conservation Areas with requisite shoreline protections in each Area. Additionally protections are afforded to Buffer Management Areas within 100 feet of mean high tide and tidal wetlands. The 2004 VIMS Shoreline Inventory found 52% of the 171 miles of shoreline were bulkheaded or rip-rapped


Actions:

  1. DNR and MDE will encourage use of alternative shoreline stabilization methods (e.g., non-structural), both for new and retrofitted shoreline stabilization applications and provide information and technical support to decision makers to ensure permit applications for new shoreline stabilization promote essential wildlife and fish habitat through alternative designs which favor the environment. Modify action to “identify incentives”, consolidate FW 1.9.1 – FW 1.9.3

  2. DNR will identify and encourage retrofits through incentives for existing structures that have deteriorated and promote the use of salt marsh, artificial habitat features (e.g., planter box, Spartina) or riprap where appropriate. consolidate

  3. DNR will provide incentives for use of more environmentally sensitive practices. consolidate

  4. WC will identify situations where sensitive habitats are not protected by the existing zoning and subdivision laws and consider implementing incentives for activities that protect these areas. For example, maintenance of allowable density on a parcel where a developer agrees to preserve a vegetated shoreline buffer that exceeds the legal requirement. The county may begin by reviewing the criteria and checklist accounting system developed by the American Planning Association. Modify for monitoring and emphasis on aquatic sensitive areas

  5. WC will continue to work with existing programs (such as Rural Legacy, Forest Legacy, Program Open Space, and CREP) to protect natural shoreline and adjacent landward areas through the purchase of development rights or shoreline easements (or fee simple purchase). Keep

  6. WC will investigate the use of 'rolling easements' in other jurisdictions that are highly susceptible to sea level rise and investigate the feasibility of purchase of 'rolling easements' from tidal shoreline developers on a voluntary basis. Investigate alternatives for undeveloped canals. Delete
