2017 Understanding the Impacts of the Atlantic Sea Scallop Fishery on Loggerhead Sea Turtles (5/5/2017) - Project Title: Understanding the Impacts of the Atlantic Sea Scallop Fishery on Loggerhead Sea Turtles Year: 2017 Principle Investigators: Samir Patel Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program Our primary objectives are to examine sea turtle distributions, behavior and foraging habits, improve sea turtle bycatch estimates, identify factors impacting bycatch rates and determine the role loggerheads play in impacting sea scallop health. The information collected will aid in evaluating loggerhead abundance estimates, developing scallop-harvesting strategies that minimize harm to sea turtles, and defining critical habitats for loggerheads. To build upon the success of prior Coonamessett Farm Foundation (CFF) turtle behavioral ...read more
2017 Development of an Extended Link Apron: A Broad Range Tool for Bycatch Reduction (5/5/2017) - Project Title: Development of an Extended Link Apron: A Broad Range Tool for Bycatch Reduction Year: 2017 Principle Investigators: Farrell Davis, Ricky Alexander and Liese Siemann Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program The goal of this project is to further develop a gear design utilizing two links to increase the inter-ring spacing in the dredge apron. The extended-link configuration encourages the mechanical sorting of pre-recruit scallops and flatfish. Previously, CFF tested a configuration that increased both the vertical and horizontal inter-ring space by orienting the extensions in both directions, creating a Bi-directional Extended Link Apron (BELA). While the ...read more
2017 Habcam – Year 4 (5/5/2017) - Project Title: An Optical Assessment of Sea Scallop / Predator Abundance and Distribution in the Nantucket Lightship Closed Area and Surrounds in Coordination with the VIMS Dredge Survey Year: 2017 Principle Investigators: Jason Clermont, John Ceccolini, Ronald Smolowitz, Liese Siemann Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program We propose to use the Habcam V3 towed instrument system to conduct the fourth year of optical survey of the large scallop recruitment event south of the Great South Channel. The primary purpose of this survey is to document distribution, survival, and growth of the large cohort of scallops spawned in late ...read more
2017 Improving a Low Profile Dredge Using Computational Fluid Dynamics and Flume Tank Testing (5/5/2017) - Project Title: Improving a Low Profile Dredge Using Computational Fluid Dynamics and Flume Tank Testing Year: 2017 Principle Investigators: Liese Siemann, Farrell Davis Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program Our main objective will be developing an improved low profile dredge design based on flume tank testing and computer simulation results. We plan to (1) simulate the performance of different dredge configurations using computational fluid dynamics (CFD) models, (2) develop a modular scaled dredge to examine the impacts of changing the geometries of scallop dredges, and (3) test the scaled dredge in multiple configurations in a flume tank at scaled ...read more
2017 Northern Georges Bank Bycatch Survey (5/3/2017) -   Project Title: Optimizing the Georges Bank Scallop Fishery by Maximizing Meat Yield and Minimizing Bycatch Year: 2017 Principle Investigators: Luisa Garcia, Liese Siemann Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program This project is a continuation of the current seasonal bycatch survey being conducted by CFF. The project will consist of eight 7-day survey trips aboard commercial scallop vessels occurring every even month from July 2017 through June 2018, as well as trips in September and January. Vessels will be equipped with two Coonamessett Farm Turtle Deflector Dredges (CFTDD), one with an experimental 5-row apron and a 1.5:1 twine ...read more
Southern New England Juvenile Fish Habitat Research (10/19/2016) -   Project Title: Southern New England Juvenile Fish Habitat Research Year: 2016 Principle Investigators: Liese Siemann Client: BOEM The goal of this project is to provide BOEM with fish catch data and benthic habitat data where dredge survey locations overlap with BOEM lease areas in southern New England waters. Combined catch numbers and relative abundance data from CFF winter dredge surveys and NEFSC spring and fall bottom trawl surveys will be used to determine if winter flounder, windowpane flounder, yellowtail flounder, and monkfish presence might change seasonally. In addition, habitat / substrate preferences of fish species during the months of December through ...read more
Development of an Ecosystem Friendly Scallop Dredge Bag (4/19/2016) - Project Title: Development of Ecosystem Friendly Scallop Dredge Bags: Tools for Long-Term Sustainability Year: 2016 Principle Investigators: Farrell Davis, Chris Parkins, Melissa Campbell Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program The goal of the project is to develop an alternative gear design to reduce the impact of fishing effort on pre-recruit scallops. The project will utilize six 7-day research trips to test an extended link apron, adding two consecutive links between the 4 inch rings in the vertical and horizontal direction. Extended link design increases inter-ring spacing of the apron encouraging the mechanical sorting of pre-recruit scallops. Gear testing will ...read more
A Modified Flounder Sweep for Bycatch Reduction (4/19/2016) - Project Title: A Modified Flounder Sweep for Flatfish Bycatch Reduction in the LAGC Scallop Fishery Year: 2016 Principle Investigators: Chris Parkins & Farrell Davis Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program The goal of this project is to test a modified flounder cookie sweep on the outer bale bars of the scallop dredge in the LAGC commercial scallop fleet and film fish-dredge interactions to monitor the effectiveness of gear modification. Catch data will be recorded during 25 DAS aboard an LAGC vessel during commercial fishing trips where catch is retained. If the gear modification proves successful, future testing can ...read more
2016 Drivers of Dispersal and Retention in Recently Seeded Sea Scallops (4/19/2016) - Project Title:  2016 Drivers of Dispersal and Retention in Recently Seeded Sea Scallops Year: 2016 Principle Investigators: Ricky Alexander, Liese Siemann, & Samir Patel Client: NOAA/NMFS Atlantic Sea Scallop Research Set-Aside Program The encompassing goal of this project is to demonstrate the feasibility of a seeding program to enhance and stabilize scallop recruitment while documenting the factors that affect seed survival. Specifically, research will focus on scallop dispersal and survival in offshore populations with an emphasis on the factors influencing dispersal in the days immediately following seeding operations. During each research trip, the experiment will compare scallop retention and habitat conditions ...read more
