Boat-Based Recreational Fishing Catch And Effort In Cockburn Sound And Owen Anchorage During 1996/97, 2001/02 And 2005/06, Neil Sumner, Eva Lai

Fisheries research contract reports

This report presents catch and effort estimates from three surveys of boat-based fishers. Recreational anglers used lines with bait or lures to catch fish. Boat-based crabbers either use drop nets or catch crabs by hand whilst diving or snorkelling. Surveys of recreational fishing activities that included coverage of Cockburn Sound were conducted during 1996/1997 (Sumner and Williamson, 1999), in 2001/02 (Sumner and Malseed, 2004) and in 2005/06 (Sumner et al., 2008). The 1996/97 and 2005/06 surveys covered the entire West Coast Bioregion of Western Australia, which includes Cockburn Sound. There was a need to re-analyse data collected during the …

Aquatic Fauna - Biological Survey Ten Mile Brook Dam Margaret River - Fisheries Research Contract Report No. 22, 2010, Craig Lawrence, C Hugh, Renae Larsen, J Ledger, Phil Vercoe

Fisheries research contract reports

Ten Mile Brook Dam has a surface area of 275 Ha and receives water from a 10 km2 catchment (Figure 1). It has a total storage capacity of 1,691 ML. At the time of this study the dam was 89 % capacity (1,511 ML), however as recently as June 2009 water storage was as low as 663 ML (39 % capacity).

In order to improve the drinking water supply to the town of Margaret River, the Water Corporation is investigating the option of pumping bore water into Ten Mile Brook Dam. This would remove the need to transfer water from …

Social And Economic Evaluation Methods For Fisheries: A Review Of The Literature - Fisheries Research Contract Report No. 21, 2009, Simon Vieira, Jacki Schirmer, Edwina Loxton

Fisheries research contract reports

The Department of Fisheries Western Australia is responsible for managing Western Australia’s fishery resources in a way that is consistent with the principles of Ecologically Sustainable Development (ESD). Implementing these principles in a practical manner for fisheries has involved the development of a new management approach that is termed Ecosystems Based Fisheries Management (EBFM). This process incorporates social and economic factors into the management process along with biological and environmental considerations, at both the Fisheries and regional levels.

To date, minimal work has been done to address social and economic factors in accordance with EBFM. This is primarily due to …

Improvement And Evaluation Of Greenlip Abalone Hatchery And Nursery Production. Final Frdc Report - Project 2003/203, Sabine Daume

Fisheries research contract reports

A range of experiments aimed at optimizing broodstock performance and nursery culture of greenlip abalone (Haliotis laevigata) were undertaken in Western Australia. Factors investigated that can potentially influence broodstock performance were natal source (wild-caught or farm-grown) and broodstock diets (red algal diet or formulated diet varying in levels of an important fatty acid). Wild-caught broodstock, feeding mainly on a red seaweed diet, produced eggs with higher concentrations of an important fatty acid, arachidonic acid, whereas farm-grown broodstock, feeding on a commercial formulated diet, altered the concentration of fatty acids of the eggs. Feeding farm-grown broodstock natural diets like …
