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 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. 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).

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).

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).

Download or read book Scallop Mark-recapture to Estimate Density Dependent Natural Mortality and Growth written by David B. Rudders and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural mortality, growth and movement are fundamental processes critical to understanding and describing population dynamics. These population characteristics not only inform and influence stock assessment models, but are also highly relevant with respect to the design and implementation of management strategies to meet fishery objectives. For many species, including sea scallops, these population parameters are difficult to measure due to the nature of the habitats inhabited and as a result, minimal information is often available. In many cases, what estimates do exist are highly uncertain as a result of both observation and process error. The uncertainty of these parameters is exacerbated for a species such as the sea scallop whose life history strategy is predicated on large, episodic recruitment events where natural mortality and growth may vary as a function of animal density. In 2015, resource surveys by the Virginia Institute of Marine Science (VIMS) and others observed what appeared to be an exceptionally large incoming year class of sea scallops throughout the Mid Atlantic Bight (MAB), with the locus of the event located in the Elephant Trunk Closed Area (ETCA). At the time of first encounter, these animals were roughly two years old and the scale of the event in terms of the spatial extent and magnitude was extensive. Multiple surveys delineated the distribution of the event and confirmed the enormous magnitude of scallops in the area, but critical questions remained. What is the survival rate of the unfished cohort (i.e. natural mortality rate)? What is their growth rate? Would the scallops survive? Would they grow at rates similar to what was expected? Would the animals move either inshore or offshore to a different habitat? To address these questions, we conducted a sea scallop mark-recapture study in the area of newly recruited scallops in the ETCA.
