Validation Of An Individual Quick Freezing (Iqf) Process To Reduce Vibrio Vulnificus Numbers To <30mpn/G In Raw Oysters, Ron Bevans, Luke Cowart

Reports

This validation study was conducted during the months of July, August and Sept., 2003. The Food and Drug Administration and the Interstate Shellfish Sanitation Conference require that oysters used for a validation study are collected during the same processing day, are from the same lot of shellfish, and have an adjusted geometric mean (AGM) MPN of at least I 00,000/g of Vibrio vulnificus as an initial load. The oysters were removed from refrigerated storage and held at 71 °F (21 °C) for 40-45 hours prior to freezing in order to achieve a minimum AGM of 100,000/g Vibrio vulnificus . After …

Measures Of Capacity In A Multispecies Danish Fishery, Neils Vestergaard, Dale Squires, James E. Kirkley

VIMS Books and Book Chapters

Different measures of capacity utilization (CU) are applied to the Danish Gillnet fleet using the Data Envelopment Analysis (DEA) approach. The potential capacity output is found using the output-orientated measure. The CU measures are the partial capacity utilization measure and the Ray measure (DEA measure). The average CU of the Danish Gillnet fleet was found to be between 0.85 and 0.95 depending on the measure used. Since the Danish Gillnet fleet participates in a multispecies fishery regulated by TACs (output) the excess capacity was also found for each species. The results show higher excess capacity for cod and sole than …

Capacity And Offshore Fisheries Development: The Malaysian Purse Seine Fishery, James E. Kirkley, Dale Squires, Mohammad Ferdous Alam, Ishak Haji Omar

VIMS Books and Book Chapters

Many developing countries pursue offshore fisheries development strategies to increase protein supply, expand employment, earn foreign exchange, and militate the conflict between large- and small-scale fisheries over the inshore resource stocks. This study evaluates the economic success of Peninsular Malaysia's offshore fisheries development policy for the west coast purse seine fleet, finding it has largely succeeded on economic grounds

Assessing Capacity And Capacity Utilization In Fisheries When Data Are Limited, James E. Kirkley, Rolf Fare, Shawna Grosskopf, Kenneth Mcconnell, Dale E. Squires, Ivar Strand

VIMS Books and Book Chapters

Excess capacity is globally recognized by resource managers as a major problem for fisheries. Yet, the concept of capacity remains vague, ill-defined, and often ambiguous. Presently, measuring capacity and capacity utilization in fisheries has become more important or of greater public concern than ever because of various national and international agreements or policies to reduce capacity in fisheries throughout the world. In this study, we propose data envelopment analysis (DEA) as one method that may be used to calculate a production-oriented measure of capacity. We conclude that although the DEA approach is limited and does not provide measures of capacity …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2002-December 2002 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver

Reports

The Virginia Institute of Marine Science (VlMS) has conducted a juvenile striped bass seine -ey from 1967 through 1973 and from 1980 through the present. The primary objective has been the monitoring of the relative amnal recruitment success ofjuvenile stripedbass in the spawning and nursery areas of Lower Chesapeake Bay. Initially (1967-1973), the survey was funded by the U.S. Fish and Wildlife Service and when reinstated in 1980 with funding from the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey, support of the program has been jointly made through the Sportfish …

Diet Of The Sandbar Shark, Carcharhinus Plumbeus, In Chesapeake Bay And Adjacent Waters, Julia K. Ellis

Dissertations, Theses, and Masters Projects

The sandbar shark, Carcharhinus plumbeus, is the most abundant large coastal shark in the temperate and tropical waters of the northwest Atlantic Ocean. The Chesapeake Bay, Virginia and adjacent waters serve as a nursery ground for C. plumbeus as well as many other fauna. Characterizing the diet of a higher trophic level predator such as the sandbar shark sheds light on a small portion of the temporally and spatially complex food web in the Bay. This study describes the diet of the sandbar shark, highlighting differences in diet within various portions of the nursery area, as well as ontogenetic changes …
