income due to shrimping. Data were also gathered on total variable costs,
total fixed costs, and net revenue by vessel size. Other data gathered
included information on marketing channels, and subjective appraisals of the
problems confronted by recreational and commercial shrimpers. Although much
data were obtained, and despite elaborate measures taken to obtain the
cooperation of the interviewees, there was considerable reluctance on the part
of the shrimpers to reveal catch, income, or even cost data.

Coastal Fisheries Management. Can. J. Fish. Aquat. Sci., 50:2029-2042.
Marine fisheries refugia, unaltered areas that serve as sources of
replenishment, can potentially compensate for recruitment and ecosystem over
fishing and enhance fishery yields for some coastal stocks. The efficacy of
Refugia in fisheries management is virtually untested, despite the existence
of many marine parks and reserves. Evidence from existing marine reserves
indicates that increased abundance, individual size, reproductive output, and
species diversity occurred in a variety of marine species in refuges of
various sizes, shapes, and histories in communities ranging from coral reefs
to temperate kelp forests. Fishery yield enhancement in areas surrounding
refuges occurred in the few studies where yields were examined. The export of
propagules required to enhance fisheries in areas surrounding refugia adds a
level of complexity to the design of fishery refugia beyond that of
terrestrial reserves. Fishery refugia design should consider species life
fisheries, oceanographic regimes, habitat quality, and socioeconomic factors.
Further evaluation of existing marine refuges and the investigation of
experimental refugia over appropriate time spans will help resolve questions
of optimal sizes, shapes, and distribution of fishery refugia.

In this paper, we examine the domestic welfare effects of environmental
regulations in the context of distorted trade markets.

Food prices, as measured by the Consumer Price Index (CPI), increased
1.2 percent in 1992, less than half the 1991 price increase of 2.9 percent.
The 1992 increase was the lowest since 1967, when the index rose 0.9 percent.
Higher charges for processing and distribution mainly accounted for the 1992
increase. The prices farmers received for commodities, as measured by the
farm value of USDA s market basket of foods, declined 2.5 percent. The farm
value share of the food dollar spent in grocery stores in 1992 was 26 percent,
down from 27 percent in 1991. The farm-to-retail price spread of USDA s
market basket of foods rose 2 percent, partly reflecting higher prices of
inputs, such as labor.
