shrimp trawling operations. Freezer units, brine immersion tanks, and onboard
fish meal plants, an extra crew member, and a mothership concept are the
systems evaluated. Break-even prices are estimated that would be necessary to
cover operating costs and a 10 percent return on investment. Additionally,
problems in traditional work patterns, crew incentives, and institutional
arrangements are discussed. Comparison of estimated break-even prices with
recent market prices indicate that none of the proposed systems are viable
except under very restrictive conditions. The mothership or tender vessel
concept shows the most economic potential but is plagued with problems of
coordinating a large number of vessels in an industry where independence of
operation is valued highly. The analytical model presented may be used to
evaluate other systems not considered directly in this study.

Conservation Zone Closure off Texas." Marine Fisheries Review,
44(9-10):31-37.
A yield per recruit analysis and a simulation model of shrimp fishing
show that an increase in brown shrimp yield was realized from closure of the
Fishery Conservation Zone (FCZ) off Texas during May-July 1981. Yields were
11.7 million pounds greater (29 percent) than would have been expected with
the FCZ open during May-August 1981. Some of the increase in yield was made
at the expense of standing stock. Projections over the fishable lifespan of
the shrimp indicate that yields will be increased 4 million pounds (7 percent)
due to the FCZ closure.

This paper analyzes the 1960-1985 commercial catch statistics for
Penaeus aztecus (brown shrimp), Penaeus setiferus (white shrimp), and Penaeus
duorarum (pink shrimp) from the U.S. Gulf of Mexico shrimp fishery. This
analysis is an update of the assessment (Nichols, 1984) presented at the
Southeast Fisheries Center's Second Stock Assessment Workshop (Miami, May,
1984).

Tortugas Pink Shrimp Fishery." North American Journal of
Fisheries Management, 6:339-343.
Portions of a 1979 analysis dealing with optimum size considerations in
the Tortugas, Florida, pink shrimp (Penaeus duorarum) fishery are updated.
The 1979 management advice remains essentially the same. The current target
minimum size of 103 mm total length theoretically should produce a 14 to 20%
gain, compared to unregulated conditions, in weight yields from shrimp
recruiting through the closure area during the peak fishing season. Gains in
dollar value (ex-vessel gross revenue) due to closure would be from 45 to 64%
during the peak season. However, because of the natural protection already
provided by untrawlable bottoms in some areas where small shrimp are abundant,
these percentage gains probably are overestimates.
