Fishing Effort for Blue and White Marlin in the Atlantic Ocean."

Assessments of the status of stocks of blue marlin (Makaira nigricans)
and white marlin (Tetrapterus albidus) have been performed by Farber and
Conser (1982) for the Atlantic Ocean using the data base collated by the
International Commission for the Conservation of Atlantic Tunas (ICCAT).
These analyses used production models relating yield to effort. Average size
data are available from both the Japanese longline fishery and from the
recreational fishery. Trends of average size are analyzed in this study and
related to fishing effort. The results of these analyses are compared to the
production model results assuming single Atlantic wide stocks of blue and
white marlin.

In conducting this evaluation of large coastal shark groups, the
committee found that for many species considered, shark abundance in waters
off the U.S. Atlantic and Gulf of Mexico coasts is depressed due to fishing
removals. Catch rate information indicates that the abundance of many of the
species and species groups could have declined by about 50 to 75% from the
early 1970's to the mid 1980's. The downward trend in available CPUE
observations probably accurately reflects further shark abundance decreases
since 1986 when shark catches dramatically increased until the 1993 quota was
adopted. Recovery of this resource to levels of the 1970's will be slow
(perhaps 30 years or more in some cases), due to the relatively low intrinsic
rates of increase exhibited by most shark species. Measuring recovery or
decline under a TAC implemented in 1993, even with precise abundance indices,
may not be possible for a decade or more. Given the information available,
increases in the TAC for sharks were considered risk prone with respect to
promoting stock recovery. In fact, considering the reproductive profiles of
sharks and the general insufficiency of fishery data upon which to base
analyses, any TAC might be considered risk prone relative to stock recovery of
large coastals. To increase the probability of recovery, the single most
important measure, supplemental to controlling the annual harvest level, that
might be implemented is a closure of nursery grounds to directed fishing
during the pupping season. The greatest impediments to improving shark stock
assessments continue to be the general lack of species and size specific catch
(landed and discarded) and effort data, as well as only limited fishery
independent measures of shark abundance and productivity.
