Distribution, abundance and population dynamics of beachworms (Onuphidae) in Queensland/NSW and the impact of commercial and recreational fishing

To date, very little research has been done on Australian beachworms (Family: Onuphidae), yet recreational fishing is a very popular activity in Australia and a variety of invertebrates, including beachworms, is used for bait. Exploitation of these animals for use as bait may remove considerable...

Symposium on parasitic diseases of aquatic animals: 10th International Congress of Protozoology

A symposium on protozoan diseases of aquatic animals was planned as a feature of the 10th International Congress of Protozoology. Speakers invited for the symposium were: Dr Mike Hine, NIWA, NZ, an expert on oyster and fish diseases, Prof. Tim Flegel, Mahidol University, Bangkok, an expert on prawn...

Objectives

1. Provide a comprehensive description of the beam trawl fishery
2. Estimate the costs imposed by beam trawling on recreational fishers and other commercial operators harvesting the resource
3. Estimate the net economic benefits or costs to the competing sectors and the broader community of altering the level of beam trawl activity in each river system
4. Assess management options currently under consideration including possible levels of compensation

Summary

The study estimates the benefits and costs of the beam trawl fishery to the Queensland economy in each of four study areas. Benefits are values of catches and costs include catching costs and costs imposed on the recreational and otter trawl fisheries, through by-catch, congestion and habitat disturbance in the case of the recreational fishery, and through competition for prawn stocks in the case of the otter trawl fishery. Chapter 2 of the study provides a comprehensive review of the beam trawl fishery. Chapters 3 and 4 deal with the interactions between the beam trawl fishery and the recreational fishery. Chapter 5 models these interactions together with the interaction with the otter trawl fishery. Chapter 6 summarises the study and presents the conclusions.

Three surveys were conducted of the beam trawl and related fisheries: a survey of the recreational boat and shore fishery in areas nominated by the Project Steering Committee; a beam trawl by-catch survey; and an income, costs and returns survey of beam and otter trawl vessels. Using the results of these surveys, together with those of previous surveys, information about the prawn fisheries available in published articles and reports, and vessel logbook data, a simulation model of the beam trawl fishery and its interactions with the recreational and otter trawl fisheries was constructed. The model was used to estimate the net contribution of the beam trawl fishery to the economy in each of four study areas: Area 1 between 27°S and the NSW border,  and Areas 2, 3 and 5. The net contribution is measured as prawn revenues less all variable, annual and capital costs, and less the costs imposed by beam trawling on the recreational and otter trawl fisheries.

Trial of the use of new age-pigment-based methods for age determination of western rock lobster (Panulirus cygnus)

The Western rock lobster fishery is a valuable resource in Australia, but it is important to manage it sustainably. One way to do this is to understand the population dynamics, including the age of the lobsters. Traditional methods of measuring age, such as body size, are noy very reliable, so...
