This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the sea scallop, Placopecten magellanicus, the concepts of space and time have emerged as the basis of an effective management tool. The strategy of rotational area management has aided in the sustainability of the resource. Since 2003 with the adoption of Amendment 10 to the Fishery Management Plan (FMP), rotational area management has provided a mechanism to protect juvenile scallops from fishing mortality by closing areas based on scallop abundance and observed length distributions. Approximately half of the sea scallop industry’s current annual landings are attributed to areas under this rotational harvest strategy. While this represents a management success, it also highlights the extent to which landings and management are dependent on the effective implementation of this strategy. The continued prosperity of scallop spatial management is dependent on both periodic and large incoming year classes, as well as a mechanism to delineate the scale of a recruitment event and subsequently monitor the growth and abundance of these scallops over time. Current and accurate information related to the abundance and distribution of adult and juvenile scallops is essential for managers to respond to changes in resource subunits, especially as the resource is being managed at finer-spatial scales. Acknowledging the importance of accurate, timely, and meaningful information necessary to meet the management challenges, the Virginia Institute of Marine Science (VIMS) conducted a stratified random survey of the Georges Bank (GB) Closed Area I (CAI) and Closed Area II (CAII), as well as the southern flank south of CAII in the summer of 2020 and 2021. The primary objective of these surveys was to assess the abundance and distribution of sea scallops in this area, culminating with spatially explicit annual estimates of total and exploitable biomass by Scallop Area Management Simulator (SAMS) Area. Secondary project objectives for each survey year included: 1. Finfish bycatch species composition and catch rates, 2. Scallop biological sampling (length:weight relationship, disease, product quality, and shell samples for ageing) and 3.Sea scallop dredge performance (commercial and survey dredges).

Book excerpt: For the sea scallop, Placopecten magellanicus, the concepts of space and time have emerged as the basis of an effective management tool. The strategy of closing or limiting activities in certain areas for specific lengths of time has gained support as a method to conserve and enhance the scallop resource. In the last decade, rotational area management has provided a mechanism to protect juvenile scallops from fishing mortality by closing areas based upon scallop abundance and age distribution. Approximately half of the sea scallop industry's current annual landings come from areas under this rotational harvest strategy. While this represents a management success, it also highlights the extent to which landings are dependent on the success of this strategy. The continued prosperity of scallop spatial management is dependent on both periodic and large incoming year classes, as well as a mechanism to delineate the scale of a recruitment event and subsequently monitor the growth and abundance of these scallops over time. Current and accurate information related to the abundance and distribution of adult and juvenile scallops is essential for managers to respond to changes in resource subunits. For the present study, we conducted a stratified random survey of the Georges Bank Closed Area II (GBCA II) scallop access area and the GBCA II Extension closure to the south. The primary objective of this survey was the determination of scallop distribution, abundance and biomass in the area. In addition, we characterized the spatially explicit scallop length weight relationship, identified areas of seed and juvenile scallops, quantified species-specific bycatch, provided additional information regarding the size selectivity and efficiency of the New Bedford style commercial dredge and collected data on scallop biology and market condition. We also conducted a tow duration experiment after the conclusion of the survey to assess the impact of a shorten tow duration on scallop catch.

Book excerpt: The 1996 Northeast Fisheries Science Center sea scallop survey was conducted during July 29 - August 9 and August 15 - 26 using the RIV ALBATROSS IV. The purpose of the survey was to monitor trends in abundance, population composition, and recruitment of sea scallop (Placopecten magellanicus) resources in the Mid-Atlantic and Georges Bank regions in depths between 28-110 meters (15 to 60 fin). A total of 429 sampling tows were conducted during the 1996 survey. Survey indices of relative abundance (stratified mean number per tow) and biomass (stratified mean meat weight per tow) were calculated for the principal scallop areas within the Mid-Atlantic and USA Georges Bank regions. Indices were derived for: 1) pre-recruits [80 meat count]; 2) recruits or harvestable-sized scallops [70 mm shell height; 80 meat count]; and 3) total scallops [all sizes]. In addition, percentage distributions of the number of scallops within five meat count intervals were calculated for each stratum, area, and region. Meat count refers to the number of scallop meats per pound. Results of the 1996 survey indicate that the indices of relative abundance and biomass in the Mid-Atlantic region decreased substantially from the relatively high levels observed in 1995. In the USA Georges Bank region, the indices of relative abundance and biomass increased substantially from the 1995 value. The most substantial increases of abundance and biomass indices occurred in the Northern Edge and Peak area; however, the indices decreased in the Southeast Part area between 1995 and 1996. . The Mid-Atlantic scallop resource had a high proportion of small scallops in 1996: 17% of the scallops caught were >80 count and 56% were in the 80-40 count category. Of the harvestable biomass
