A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia

Fisheries management papers

In March 1986 discussions were commenced between officers of the Fisheries Department and the Australian Fisheries Service concerning management measures for trawl fishery in the Great Australian Bight. These measures were considered necessary as a Western Australian Company (Toskel Fishing Co.) had commenced fishing the area. Given the excess fishing capacity in other Australian trawl fisheries it was considered advisable to institute management at an early stage and control development of this deep water fishery. Concurrent with these developments, mainly directed towards the control of larger trawlers in deeper waters, several small Western Australian trawlers operating out of Esperance and …

Report Of The Rock Lobster Industry Advisory Committee To The Hon. Minister For Fisheries., Rock Lobster Industry Advisory Committee

Fisheries management papers

The Committee recognises that the exploitation rate on the rock lobster stocks is very high and that this factor is a major importance in formulating the advice on management measures. However, the Committee also recognises the high level of capital investment in the industry and that any recommendation which leads to a significant change in the management rules is likely to have a far reaching effect on many of the participants. Accordingly, the Committee endeavours to reduce to a minimum the year to year changes in the management rules. When changes are required the Committee places considerable weight on matters …

The Shark Bay Scallop Fishery: Discussion Paper, L. M. Joll

Fisheries management papers

Studies of the biology of the saucer scallop Amusium balloti in Shark Bay show that it is a highly fecund, broadcast spawner, with a long breeding season (from April to December). It is also a fast growing species, with the bulk of the recruits from a breeding season reasing fishable size by April/May of the next year, at which time they also enter their first breeding season. In recent years, however, the earlier part of the breeding season appears to have been the most important for production of recruits.

Further Options For Management Of The Shark Bay Snapper Fishery : Discussion Paper., P. Millington

Fisheries management papers

A limited entry fishing regime for snapper was introduced in Shark Bay in order to constrain growth in fishing effort. Additional measures were introduced to reduce the number of vessels in the fishery, control areas fished and limit permitted fishing gear, with the ultimate objective of reducing catches from traditional fishing areas to long term sustainable levels.

Uptake And Internal Distribution Of Exogenously Supplied Amino Acids In The Pacific Oyster, Crassostrea Gigas (Thunberg), Michael A. Rice, Grover C. Stephens

Michael A Rice

A technique is described in which irrigation of the mantle cavity of oysters, Crassostrea gigas, induces pumping at steady rates. Simultaneous net influx of 10 amino acids (asp, glu, asn, ser, gly, tau, ala, val, phe, lys) is observed by high-performance liquid chromatography (HPLC). Individual amino acids exhibit first-order exponential depletion from an initial medium concentration of 2.0 μM. Influx of radiolabeled alanine corresponds very closely to net entry of alanine as estimated by HPLC. Therefore, net entry of alanine from dilute solution (5 μM) occurs. The entry of alanine is well described by Michaelis-Menten kinetics with a maximum influx …

Population Dynamics And Habitat Partitioning By Size, Sex, And Molt Stage Of Blue Crabs Callinectes Sapidus In A Subestuary Of Central Chesapeake Bay, Anson H. Hines, Romauld N. Lipcius, A. Mark Haddon

VIMS Articles

Abundances, size-frequency distributions, sexual composition and molt-stage composition of blue crabs Callinectes sapjdus were measured during 1983 to 1985 in the Rhode River, a subestuary of central Chesapeake Bay, USA. Crabs at the mouth and head of the river basin were sampled with monthly triplicate otter trawls. Crabs in the principal tidal creek of the river were sampled 3 d a week with a fish weir, which caught crabs moving upstream and downstream separately. Crabs exhibited consistent, marked seasonal cycles in abundance as well as considerable annual variation in July peak abundances. New recruits entered the subestuary in late fall …

Western Rock Lobster Industry Compensation Study. Report To The Rock Lobster Industry Advisory Committee By Arthur Young Services., Arthur Young Services

Fisheries management papers

Terms of reference are outlined in letter dated 11 August 1986. The Fisheries Department seeks to reduce western rock lobster fishing capacity to ensure the long-term viability of the fishery and has asked us to evaluate the financial implications of a number of specific resource management proposals.

The American Oyster Crassostrea Virginica In Cheapeake Bay, Dexter Haven

VIMS Books and Book Chapters

The American Oyster (Crassostrea virginica) is widely distributed in Chesapeake Bay where it grows in the intertidal zone to depths of about 6.5 m. The salinity range over which it occurs, is from about 5 to 34 ° /oo. It is most abundant in protected embayments where bottoms are a firm sand-clay mixed with shelly material. This bivalve is a filter feeder, and ingests planktonic material which it strains from the water with its gills. Spawning occurs in Chesapeake Bay from June through September, and the eggs and resulting larvae are widely distributed during their 10-20 day planktonic life.

A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1987, Joseph G. Loesch, William H. Kriete Jr., Bruce W. Hill

Reports

Internal anchor tags with external tubes were used to tag 1,986 striped bass in the James River in the Spring of 1987. The total number tagged was adjusted (at this time) to 823 because of observed and suspected tagging mortality. The available stock of striped bass in the Spring contained both young resident fish and mature nonresident fish which left the area of capture after spawning, presumably to migrate north in coastal waters. The exodus of the mature fish after spawning and the absence of a commercial fishery resulted in only 42 tag returns as of Spring 1988. This proportion …

Neobivagina agonostomi (Sandars, 1945} Dillon and Hargis, 1965, from the gills of Aldrichett~ forsteri, is redescribed; a new locality record is reported for Neobivagina agonostomi.

Striped Bass Research, Virginia - Annual Report 1986-87, Virginia Institute Of Marine Science

Reports

The research reported herein is directly in response to priorities established in the "Action Plan" of the Emergency Striped Bass Study (the Chafee Amendment (PL 96-118) of the Anadromous Fish Conservation Act (PL 89-304)). The Amendment was the result of a decline in striped bass landings along the Atlantic Coast that began in the mid-1970's. The Virginia Institute of Marine Science (VIMS) ha~ previously conducted a juvenile striped bass seining program from 1967 through 1973 which was discontinued at that point due to a loss of funding. The program was reinstated in 1980 with funding from the National Marine Fisheries …
