Much information biologists need to do their job comes from fishermen's logbooks. These logbook data are confidential by law. No single log record, or single skipper's log information can be made available to anyone else. What use is made of these log records, and why are they useful is a...
Petrale sole are taken commercially from Santa Barbara, California, to Hecate Strait, British Columbia. These large deep-bodied flounders are one of the major contributors to Oregon's trawl fishery, as well as those of Washington, British Columbia, and California. Only the Dover and the English soles appear in greater quantities. This...
Species associations of fifteen major commercial groundfish species in the
northeastern Pacific ocean and their spatial and temporal characteristics were studied
using Oregon bottom trawl logbook data, 1987 to 1993. Screening procedures were used
to remove questionable data from the original logbook files, which resulted in the
exclusion of information...
Despite the fact that fishing is an inherently uncertain business, risk has rarely
been formally recognized in fisheries science or management. Few fishery
management plans include any form of risk assessment and those that do focus on
minimizing risk caused by uncertainty associated with markets and environmental
conditions. Fishermen's attitudes...
The groundfish trawl fishery operating off the coasts of Oregon
and Washington 1985-1987 caught six major assemblages of species
which could be treated as units in developing mixed-species
management plans. Eighty-one percent of the tows observed on
commercial vessels were consistently placed in one of the assemblage
designations using three...
Main fishing gear in Thailand was otter board trawls. More than 70% of the total Thai fishing vessels had been using this fishing gear, as well as push net which was restricted targeting for demersal resources. Due to the 2.5 cm fine mesh size, juvenile economic species had been caught...
