The Fisheries of Hawaii and U.S.-associated Pacific Islands

In the late 1980's and early 1990's, significant changes occurred in the fisheries of Hawaii. Expansion and diversification of pelagic fisheries and growth (including industrialization) of fisheries that, in at least some cases, had been largely recreational or artisanall ed to fear of overfishing and problems in allocation among fishery sectors. Combined with establishment of limited entry programs in Hawaii fisheries (bottomfish, longline, and lobster), this led to anticipation that similar growth might occur in Guam, the Northern Marianas, and American Samoa.

Mechanisms of upper-ocean thermal variability in a 1970-1988 simulation and observations

EXTRACT (SEE PDF FOR FULL ABSTRACT): Variations in temperature that occurred in the North Pacific thermocline (250 to 400 meters) during the 1970s and 1980s are described in both a numerical simulation and XBT observations.

Zooplankton standing stock and community structure along Karnataka Coast, west coast of India

Distribution of zooplankton along two transects at Karwar and Ratnagiri, west coast of India, was studied. The standing stock of zooplankton was relatively high in the neritic zone with the highest value [358 ml/100 m super(3)] in the area off Ratnagiri due to the aggregation of fish larvae and hydromedusae. Maximum zooplankton production in these areas was noticed with the low temperature and low dissolved oxygen during postmonsoon season. At Karwar the highest biomass [188 ml/100 m super(3)] was observed from the nearshore station due to swarms of the cladoceran Penilia avirostris and the pteropod Cresis acicula when the salinity was low. The fluctuations in numerical abundance and percentage composition of all the major planktonic groups are discussed. The fishery of these areas is compared with the zooplankton standing stock.
