Project Goals: 1. To design and test modifications to sea scallop trawl nets enabling reduction in bycatch of regulated finfish species. 2. To test the viability of using smaller trawls, with modified sweeps, to catch larger sizes of sea scallops.

Report On A Live Flounder Holding Project On The Eastern Shore Of Virginia, Wec Terry

Reports

The goals and objectives of this Grant Program were to ascertain if live fluke could be held in a "low tech" flow through seaside tank system and sold later when market prices were higher? We have also tried to determine how wild fluke will be affected by changes in temperature and climate and whether they can be trained to feed on raw fish or other feed? We sought to determine if weak and stressed fish can be identified and removed from the tank prior to affecting healthy fish in the tank? And if not, can any resulting disease in the …

Development Of Clear Plastic Containers For Pasteurizing Crab Meat, Johnny Graham

Reports

Two containers with two different thicknesses ( 60 and 90 mil) were developed and seven lid stock materials with five different sealants were evaluated. In addition, two trays and three different film types were also tested and evaluated for this project. All containers and combinations were not successful. All containers leaked as a result of the pasteurization process. The microbiological tests (aerobic plate counts) and Gram stain test data indicated spoilage bacteria present in the meat samples in each container following refrigerated storage.

The 307 cups were often overfilled, perhaps stressing the lidding seal. The 404 cups were under filled …

Grow-Out And Marketability Evaluation Of Triploid Deby Oysters, Gustavo Calvo

Reports

Triploid DEBY clearly outperformed their diploid counterparts in terms of survival, growth and condition over the course of this study at the site of Sweet Amalia Oyster Farm in Mathews, VA. By November 2004, when oysters were approximately 28 month old, cumulative mortality was 11 % in triploids and 43% in diploids. At that time, 41 % of the triploids were of market size (3 inch) whereas none of the diploids had even attained 2.5 inch. Condition of triploids and diploids similarly increased in fall 2003 and remained high over the winter and spring 2004. However, while condition decreased slightly …

Development Of Grow Out Techniques Utilizing The Water Column In Growing A Non Native Oyster (Crassostrea Arikensis), Andy Drewer

Reports

This project addressed grow out techniques utilizing the water column in growing non native oysters (Crassostrea arikensis) in a containerized manner. The purpose of this project was to evaluate the cost effectiveness of growing, in commercial quantities for the processing segment of the industry, a non- native oyster in different types of stackable trays suspended in the upper water column by a raft.
