Fisheries Science Update – October 2021: West Coast Demersal Scalefish Resource, Department Of Primary Industries And Regional Development, Western Australia

Fisheries occasional publications

Key points: 2021 stock assessment outcomes • The West Coast Demersal Scalefish Resource (WCDSR) is halfway into a 20-year recovery plan following a period of overfishing in the 1990s and 2000s. • This latest assessment provides an important “health check” on the recovery status. • The recovery plan is based on maintaining recreational (including charter) and commercial sector’s total fishing mortality below catch limits and protecting key spawning aggregations to recover the WCDSR by 2030. • The Department of Primary Industries and Regional Development (DPIRD) tracks recovery progress by undertaking weight of evidence stock assessments of WCDSR indicator species dhufish …

Resource Assessment Report Temperate Demersal Elasmobranch Resource Of Western Australia, Matias Braccini, Nick Blay, S. A. Hesp, Brett Molony

Fisheries research reports

This document provides a cumulative description and assessment of the TDER and all of the fishing activities (i.e. fisheries / fishing sectors) affecting this resource in WA. Future Resource Assessment Reports will assess the Statewide Sharks and Rays Resource. The report is focused on the temperate indicator species (whiskery, gummy, dusky and sandbar sharks) used to assess the suites of demersal sharks and rays that comprise this resource. These species are primarily captured by demersal gillnets used in the TDGDLF that operate in the West Coast and South Coast Bioregions. For the North Coast bioregion, no commercial fishing for sharks …

Reported Incidences Of Parasitic Infections In Marine Mammals From 1892 To 1978, John R. Felix

Zea E-Books Collection

The role of parasites in the lives and deaths of marine mammals has been scrutinized by biologists for decades, but the scientific literature prior to 1978 has been difficult to acquire and time-consuming to search. Now this new and extensive bibliography gives researchers a convenient resource for reviewing the classical literature on parasites of marine mammals so that historical infection prevalence and geographical distribution can be easily and properly assessed. This book contains detailed information about accepted (or suspected) taxonomic synonyms and geographical information about the host and/or parasite, covering the parasite groups Acanthocephala, Acarina, Anoplura, Cestoda, Nematoda, and Trematoda, …

Proceedings Of The Western Australian Dhufish Workshop 2004, Mark Pagano, Terry Fuller

Fisheries occasional publications

The Western Australian Dhufish Workshop 2004 was a joint project between Recfishwest and the Western Australian Department of Fisheries.

The workshop incorporated presentations from the Department of Fisheries, Recfishwest, the Western Australian Fishing Industry Council, Murdoch University and Challenger TAFE to showcase current knowledge relating to the iconic dhufish in Western Australia. The perspectives of a recreational fisher, a commercial wetline operator and a metropolitan charter boat operator were also presented.

Through information sharing and discussion the workshop provided a platform to better understand the fundamental issues that underpin current and future management arrangements for this valuable resource. Both commercial …

Use Of Immunoassays In Haplosporidan Life Cycle Studies, Eugene M. Burreson

VIMS Books and Book Chapters

The development of mitigating measures for the major oyster diseases has been hindered by our poor understanding of the life cycles of the pathogens. Evidence from epidemiological studies and transmission experiments suggests that an intermediate host is present in the life cycle of Haplosporidium species. Immunoassay is a valuable tool for identifying parasite antigen in an intermediate host, and, because of the potential for stage-specific antigens, assays incorporating polyclonal antibodies may be more effective than assays incorporating monoclonal antibodies. Rabbit antibody against purified spores of Haplosporidium costale recognized spores in paraffin sections of oyster tissue , but the antibody did …

Uncertainties And Speculations About The Life Cycle Of The Eastern Oyster Pathogen Haplosporidium Nelsoni (Msx), Harold H. Haskins, Jay D. Andrews

VIMS Books and Book Chapters

For 30 years, the pathogen Haplosporidium nelsoni (MSX) has been causing serious mortalities of eastern oysters Crassostrea virginica in the Delaware and Chesapeake bays of the eastern USA. Its life cycle is largely unknown, and methods for control are wanting. Breeding of resistant eastern oyster strains, at this time, offers the best hope for some degree of control of the disease. Although haplosporidians are known by their spores, controlled transmission, with one possible exception, has not been achieved in any of the 30 recognized species. Haplosporidium nelsoni rarely sporulates in eastern oysters, and this and other observations led to early …

Structure Of Protistan Parasites Found In Bivalve Molluscs, Frank O. Perkins

VIMS Books and Book Chapters

The literature on the structure of protists parasitizing bivalve molluscs is reviewed, and previously unpublished observations of species of class Perkinsea , phylum Haplosporidia, and class Paramyxea are presented. Descriptions are given of the flagellar apparatus of Perkinsus marinus zoospores, the ultrastructure of Perkinsus sp. from the Baltic macoma Macoma balthica, and the development of haplosporosome-like bodies in Haplosporidium nelsoni. The possible origin of stem cells of Marrteilia sydneyi from the inner two sporoplasms is discussed. New research efforts are suggested which could help elucidate the phylogenetic interrelationships and taxonomic positions of the various taxa and help in efforts to …

Epizootiology Of The Disease Caused By The Oyster Pathogen Perkinsus Marinus And Its Effects On The Oyster Industry, Jay D. Andrews

VIMS Books and Book Chapters

Perkinsus marinus is a protozoan parasite that causes a major disease of eastern oysters Crassostrea virginica from Chesapeake Bay south along the Atlantic coast of the USA and throughout the Gulf of Mexico. It is a warm-season disease that kills eastern oysters at temperatures above 20°C. The pathogen requires salinities of at least 12-15%0 to be active, but it persists tenaciously when low temperatures and salinities occur during winter and spring. Prolonged droughts that increase salinities cause extensions of the range of disease. In the Chesapeake Bay, mortalities begin in June and end in October, and up to 50% of …
