This book was released on 2018 with total page 39 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 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. Acknowledging the importance of accurate, timely and meaningful information necessary to meet the management challenges presented by this situation, the Virginia Institute of Marine Science (VIMS) conducted a synoptic high resolution (~450 stations) survey of the mid-Atlantic (MAB) scallop resource from the VA/NC border to Block Island, RI encompassing the Delmarva (DMV), Elephant Trunk (ETCA), and Hudson Canyon (HCCA) Access Areas, as well as the open areas of the MA resource area during the spring of 2016 and 2017. 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. 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 parameters and shell samples for ageing) and 3. Selectivity and relative efficiency analysis of the Coonamessett Farm Turtle Deflector Dredge (CFTDD).

Book excerpt: For the sea scallop, Placopecten magellanicus, current and accurate information related to the abundance and distribution of adult and juvenile scallops is essential for effective management of the resource. Scallop management is a combination of input and output controls, with a focus on spatial area management. The continued prosperity of the scallop resource and fishery 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. Acknowledging the importance of accurate, timely, and meaningful information necessary to meet the management objectives and support the fishery, the Virginia Institute of Marine Science (VIMS) conducted a synoptic high resolution stratified random survey of the Mid-Atlantic Bight (MAB) scallop resource from the VA/NC border to Block Island, RI encompassing the Mid-Atlantic Access Area (MAAA), as well as the open areas of the MAB resource area during the spring/summer of 2019 and 2020. 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 parameters, and shell samples for ageing), and 3. Sea scallop dredge performance (commercial and survey dredges).

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 observed age distribution. 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 are dependent on the effective implementation of this strategy.

This book was released on 2017 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sea scallop fishery is currently the most valuable single species fishery in the United States. Part of this success stems from a hybrid management strategy that incorporates a spatial component (rotational closed areas) with traditional fishery management approaches. While much recent attention has focused on the success of closed areas (e.g. Elephant Trunk Closed Area), production from open areas had enabled scallop landings to remain high and relatively stable over the past few years. Regardless of the management approach, timely and accurate information related to scallop distribution and biomass is critical for the effective management of the resource. This data need is essential for both the rotational access areas and the areas open to general fishing under day-at-sea (DAS) control.

This book was released on 1997 with total page 73 pages. Available in PDF, EPUB and Kindle. 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
