Interim endorsements have therefore been issued for commercial fishing within Cockburn Sound.


Variable Functional Responses Of A Marine Predator In Dissimilar Homogeneous Microhabitats, Rn Lipcius, Anson Hines Dec 1986

Variable Functional Responses Of A Marine Predator In Dissimilar Homogeneous Microhabitats, Rn Lipcius, Anson Hines

VIMS Articles

Adult soft-shelled clams (Mya arenaria) persist at low densities in Chesapeake Bay sandy habitats despite Intense predation by blue crabs (Callinectes sapidus). Clam persistence may be a consequence of variation in blue crab foraging rates as a function of clam density and sediment composition. In laboratory aquaria, we measured the functional responses (prey consumption per predator as a function of prey density) of large blue crabs to six densities of adult soft-shelled clams buried at natural depths in two sediment types (mud and sand). Functional responses in sand and mud were differentiated statistically by analyses of(1) residuals and residual sums …

The King George Sound Purse Seine Fishery Working Group Report By The Chairman Mr. R. S. Brown To The Minister For Fisheries., R. S. Brown Nov 1986

The King George Sound Purse Seine Fishery Working Group Report By The Chairman Mr. R. S. Brown To The Minister For Fisheries., R. S. Brown

Fisheries management papers

The King George Sound Purse Seine Fishery Working Group was formed to investigate the purse seine (mainly mulie) fishery in King George Sound and advise the Minister for Fisheries on options for future management. The fishery in King George Sound is unlike most fisheries because the fish stock (pilchards) which is exploited is part of a very extensive stock located right around the south and north west coast of Western Australia. Only relatively small portion of the total stock of pilchard enter King George Sound and comes under the very high exploitation there. The Working Group has proposed to the …

The Report Of The Fish Farming Legislative Review Committee., P. Rogers Oct 1986

The Report Of The Fish Farming Legislative Review Committee., P. Rogers

Fisheries management papers

In 1975, amendments to the Fisheries Act provided for the licensing and control of commercial fish farming activities and , for specific declared species, further controls on their processing and marketing. To date, marron has been the only species to be declared a "farm fish". During the last decade, much of the State's aquaculture impetus has focused on marron although more recently greater attention has been directed towards trout, yabbies and freshwater aquarium fish species. On November 19, 1984, the Marron Growers Association of Western Australia (Inc) wrote to the Minister for Fisheries and Wildlife, seeding a general review of …

Effects Of Acid Ph On Embryonic And Juvenile Freshwater Fish, Barbara A. Ramey, Lee E. Colton Aug 1986

Effects Of Acid Ph On Embryonic And Juvenile Freshwater Fish, Barbara A. Ramey, Lee E. Colton

KWRRI Research Reports

The effects of sulfuric acid on embryos, larvae, and juvenile fish were examined using standard bioassay techniques, as well as in a preference/ avoidance behavioral test. The objectives were to compare the sensitivities of the various ages of fish to acid and to assess the use of the behavioral test in a hazard assessment program. In an 8-day static renewal bioassay, embryos and larvae of the fathead minnow were not affected at a pH of 4.92 and above, but pH 3.57 produced complete mortality prior to hatching. In 96- hr acute bioassays, 8-wk juvenile fathead minnows survived 100% at pH's …

The Report Of The Southern Western Australian Shark Working Group., P. Millington Apr 1986

The Report Of The Southern Western Australian Shark Working Group., P. Millington

Fisheries management papers

The southern Western Australian Shark Working Group was formed to investigate the southern shark fishery and advise the Minister for Fisheries on options for future management. Membership comprised six fishermen from regional professional fishermen's associations and two Fisheries Department officers. The Working Group considered that each shark fisherman obtaining an entitlement should then be restricted in the length of fishing gear he can use and the number of months he can fish. The individual's time and gear entitlement would be approximately that length of gear being used and time spent fishing in a period shortly before the bench mark date. …

Columnaris Disease Of Fishes, G. L. Bullock, T. C. Hsu, E. B. Shotts Jr. Jan 1986

Columnaris Disease Of Fishes, G. L. Bullock, T. C. Hsu, E. B. Shotts Jr.

United States Fish and Wildlife: Staff Publications

Columnaris disease is an acute to chronic bacterial infection that affects anadromous salmonids and virtually all species of warmwater fishes. Davis (1922), who first described the disease, named it columnaris because the causal bacterial cells seen in wet mounts of affected gills and fins were arranged in columnar aggregations. Ordal and Rucker (1944) were the first to isolate the causal organism and, based on cellular morphology, identified it as a myxobacterium. Organisms classified in the order Myxobacterales are long, thin gram-negative rods that are motile on agar media by a creeping or flexing motion. They have a life cycle composed …


Proliferative Kidney Disease In Salmonid Fishes, R. P. Hendrick, M. L. Kent, C. E. Smith Jan 1986

Proliferative Kidney Disease In Salmonid Fishes, R. P. Hendrick, M. L. Kent, C. E. Smith

United States Fish and Wildlife: Staff Publications

Proliferative kidney disease (PKD) in salmonid fishes is caused by a poorly understood protozoan, the vegetative stages of which are known as PKX cells. The organism was initially believed to be an amoeba (phylum Sarcomastigophora) by Plehn (1924) and later by Ghittino et al. (1977) and Ferguson and Needham (1978). Similarities between PKX and oyster pathogens of the genus Marteilia led Seagrave et al. (1980) to suspect that the parasite was instead a haplosporidan (phylum Acetospora). More recent studies by Hedrick et al. (1984) and Kent and Hedrick (1985a,b) indicated that the PKX cells are pre sporogonic forms …

When the Lone Ranger finished his deed, he rode away and a person who had received help always asked someone nearby 'Who was that masked man, anyway?'


Channel Catfish Virus Disease, John A. Plumb Jan 1986

Channel Catfish Virus Disease, John A. Plumb

United States Fish and Wildlife: Staff Publications

Channel catfish virus disease (CCVD) is an acute infection of cultured fry and fingerling channel catfish (Ictalurus punctatus). The disease occurs primarily during summer and, with few exceptions, in fish less than 4 months old. The causative agent, the channel catfish virus (CCV), is a member of the herpesvirus group. Since its first identification (Fijan 1968), it has been isolated from infected fish in most areas of the United States where channel catfish are cultured.
