Aquaculture Diet Development Subprogram - Replacement of fishmeal in diets for barramundi - improving nutritive value of alternative feedstuffs using crystalline amino acids

Australia has an abundant supply of terrestrial animal and vegetable protein feeds which has the potential to at least partly if not fully replace the fishmeal presently used in compounded aquaculture diets. A major difference between marine and terrestrial protein sources is the marked difference...

Effects of Trawling Subprogram: the environmental effects of prawn trawling in the far Northern Section of the Great Barrier Reef

This report covers a five year study into the effects of trawling on seabed communities in the inter-shoal and inter-reef areas in the Far Northern Section of the Great Barrier Reef. The study arose from a GBRMPA convened scientific Workshop in 1989 to address the effects of fishing in the Great...

Objectives

1. Determine whether the Australian spanish mackerel resource, comprising four main species of the genus Scomberomorous, is exploited recreationally and commercially in three distinct areas of tropical Australia, in each of which the stock of each species is an autonomous stock
2. To determine if the species composition of the resource is the same in the 3 areas
3. To determine if the three unit stocks of search of the 3 smaller species differ as to growth rate, reproductive potential or survival rate under average environmental conditions or in consequence in composition as to sex age and size
4. To determine if the resultsobtained from Deuel surveys will be sufficient basis for allocating fishery access as between commercial and recreational fishers
5. To determine if the Deuel special survey method can yield a reliable estimate of the amount of the fishing for the small mackerels by commercial and recreational fishers in remote regions of northern Australia.

Summary

The small mackerels comprising school mackerel (Scomberomorus queenslandicus), spotted mackerel (S. munroi) and grey mackerel (S. semifasciatus) are important and valued species to recreational and commercial fishers in northern Australia. Prior to this project very little was known about the basic biology of, or fisheries for, small mackerels. Each species was found to exhibit distinct life history patterns with differing stock structures. Though there is some overlap between fisheries, there was much spatial and temporal separation of the fisheries, with gill net specialisation for each species targeted by the commercial fishery. Recreational hook and line fisheries for school mackerel and spotted mackerel were important with most of the grey mackerel harvest taken by the commercial sector.

Value added beche-de-mer products

In recent years, increased interest has been shown in the Queensland beche-de-mer industry. As a consequence, there has been a number of initiatives taken to ensure the industry will have a sustainable future. The industry, traditionally a 'cottage' industry in the past, has not been able to access...

Production technology for redclaw crayfish (Cherax quadricarinatus)

This research and development project aimed to define specific guidelines for the aquaculture production of redclaw crayfish, Cherax quadricarinatus. This aim was achieved, and a comprehensive list of such guidelines is now documented. Redclaw crayfish aquaculture was a small industry when this...
