Improving bycatch reduction strategies and escape vents in Queensland Mud Crab fisheries

The Queensland Crab Fishery is an iconic fishery, which encompasses the harvest of mud crabs (Scylla serrata, the Giant Mud Crab, and Scylla olivacea, the Orange Mud Crab) and Blue Swimmer Crabs (Portunus armatus and Portunus pelagicus), predominately using baited crab pots of various designs. The...

A comparison of the fishing characteristics and inefficiencies of different otterboard designs under field conditions

Unlike the majority of engineered equipment, the design of fishing gear is tested ultimately in its ability to take or capture live animals which are able to modify their escape responses. For this reason, increases in the efficiency of operation and optimization of hydrodynamic design are not...

QFISH Foresight Project - a strategic planning and futuring project designed to create a strong coordinated commitment by all stakeholders to an agreed vision of the fisheries of the future

The establishment in 1997of the Fishing Industry Development Council (FIDC), a peak fishing advisory body, set the scene for an examination of where Queensland’s fisheries and the fishing industry sectors were heading in the longer term. The FIDC is a high level consultative forum...

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.
