during stock collapse are extended to examine the effects of incorporating
profit motivated economic behavior of fishers. Three scenarios are examined:
(1) cooperation by fishers to achieve maximum economic yield (MEY); (2) noncooperation
resulting in open access equilibrium; (3) non-cooperation with
allocation subsidies allowing fishers to increase effort beyond the open
access equilibrium. Incorporating economic behavior in the density-dependent
catchability models may result in an alarming increase in the rate of stock
depletion, since fishers maintain high profits even during low stock
abundance. We discuss the consequences of using a model where catchability is
assumed constant for the management of fisheries on small schooling pelagic
fish.

A five year review of listed species is required under section 4 of the
endangered species act. Information published between 1978 and 1984 is
summarized in this review by NMFS, and an assessment is made of the current
status of the populations of sea turtles that are listed pursuant to the
Endangered Species Act of 1973 (ESA). The leatherback sea turtle (Dermochelys
coriacea) and hawksbill sea turtle (Eretmochelys imbricata) were listed as
endangered throughout their range on June 2, 1970. The population of Kemp's
ridley (Lepidochelys kempi) was listed as endangered on December 2, 1970. The
green sea turtle (Chelonia mydas) was listed on July 28, 1978, as threatened
except for the breeding populations of Florida and the Pacific coast of Mexico
that are listed as endangered. At the same time, the loggerhead sea turtle
(Caretta) was listed as threatened wherever it occurs. These sea turtles were
listed because, to varying degrees, their populations had declined as the
result of human activities. Many of their nesting beaches had been destroyed
by encroachment of the human population into coastal habitats. Sea turtle
populations had been reduced by uncontrolled harvesting for commercial
purposes and by mortality incidental to activities such as commercial fishing.
In many cases, existing regulatory mechanisms were not providing sufficient
encouragement for conservation.

Conservation Efforts in the Coastal Southeastern United States for
1987." Marine Fisheries Review, 50(3):43-50.
Data quantifying the cumulative acreage of coastal habitat affected by
Corps of Engineers (COE) programs that regulate development in wetlands of the
southeastern United States are provided for 1987. The National Marine
Fisheries Service (NMFS), Southeast Region, made recommendations on 4,713
water development proposals submitted by or to the COE. Of these, 1,054
proposed to alter 21,756 acres of fishery habitat through 3, 506 acres of
dredging, 2,899 acres of filling, 1,303 acres of draining, and 14,048 acres of
impounding. The NMFS did not object to alteration of 8,135 acres and
recommended the conservation of 13, 621 acres. To offset habitat losses,
7,139 acres of mitigation were recommended by NMFS or proposed by applicants
and/or the COE. Of the wetland alterations accepted by NMFS, nearly 5,000
acres involved impounding for marsh management in Louisiana. A follow up
survey of 266 permits issued by the COE during 1987 revealed that only 46
percent of NMFS recommendations were accepted by the COE. On a permit by
permit basis, 25 percent of NMFS recommendations were partially accepted, 21
percent were completely rejected, and 8 percent were withdrawn.
