model was used to estimate the changes in economic rent and bycatch of red
snapper Lutjanus campechanus, king mackerel Scomberomorus cavalla, and
Atlantic croaker Micropogonias undulatus, that would result under two fishery
management policies: Bycatch Reduction Devices (BRDs) and season/area
closures. The BRDs were found to be more effective than closures at reducing
bycatch and also less costly to fishermen. Under the BRD scenarios,
reductions in discards ranged from 20.2 to 42.5% for red snapper, king
mackerel discards fell approximately 89%, and Atlantic croaker discards fell
about 45%. Under closure policies, the change in discards ranged from a 2.1
to 15% decline for red snapper, a 1.9% increase to a 39.3% decrease for king
mackerel, and a 0.1 to 12.9% decline for Atlantic croaker. The BRD policies
produced present value 10 year rent streams (1985 US$) ranging from -$16.434
to -$27.007 million, and closure policies generated 10 year rent streams
ranging from -$35.182 to -$54.561 million.

United States, Platyhelminthes: Monogenea." NOAA Technical Report

Atmospheric Administration, National Marine Fisheries Service,
Seattle, Washington, August, 107 pp.
This manual includes an introduction to the general biology of the
platyhelminth class Monogenea, an illustrated key to the generic level, an
annotated systematic list of 108 species in 75 genera and 28 families, a
glossary of terms, a host-parasite list, a selected bibliography, and a
systematic index. The species listed have been reported on fishes taken in
the coastal waters of the northwestern Atlantic Ocean from the U.S.-Canada
border to Beaufort, North Carolina. Many of the species, however, have wider
geographic distributions that are not reported herein unless adjacent to the
geographic area above. In addition, a single species of Neodermata, Udonella
caligorum, that is found attached to copepods on fish gills is also listed.
Hennessy, David A. (1995). Microeconomics of Agricultural Grading: Impacts
on the Marketing Channel.: American Journal of Agricultural Economics,
77(4):980-989.
In this paper, I focus on how grade prices affect the provision of
product transformation skills in the food marketing system. A self-protection
model is used to show how resources are allocated to protect the potential
value of commodities in the marketing channel. Resource allocations may be
complementary, and complementarity may be exploited to expand an industry.
Further, uncertainty concerning skill levels may inhibit expansion. Because
two primary objectives of agricultural extension involve facilitating skill
acquisition and disseminating market information, the model confirms roles for
extension personnel. The optimal location of transformation skills in a
sequence of operations is also studied.

Loggerhead Turtles, Caretta, Estimated from Tag-Recapture
Experiments." Draft report, NMFS, SEFC, Pascagoula Laboratory,
Pascagoula, MS.
Recaptures of previously measured and tagged loggerhead turtles from
coastal waters of Florida, Georgia, and South Carolina were analyzed to
determine growth rates in the wild. Fitting the von Bertalanffy and logistic
growth models to loggerhead data, age estimates are computed and survival and
mortality estimates are derived. In Adult turtles mean survival rate was 0.92
and mean mortality rate was 0.08.
