1. Maintain the interest of tuna fishermen in the tagging program to encourage the return of tags from SBT caught in 1986/87
2. To "flush out" tags from fish that were caught in previous years, but for some reason were not returned

1 A method was developed to rapidly assess the effectiveness of trap designs and identify
the causes of differences in effectiveness.
2 Fish entry and escape probabilities are correlated across trap designs. The probabilities
are very high for '0' and 'S' trap designs and are much lower for the 'Z' design. Traps
with high entry and escape probabilities are best for a fishing strategy based on short
soak times, while traps with low probabilities are best for strategies using long set
times. 'Z' traps provide a greater catch per set than 'S' traps for soaks longer than about
4 h, while 'S' traps provide better catches for soaks shorter than about 4 h.

This project reports on:
1) our detailed evaluation of current methodologies for otolith chemical analysis, and our recommended procedures when electron probe microanalysis is used for stock delineation in finfish
2) our assessment of the accuracy and precision of otolith probe microanalysis relative to the scales of natural variability in otolith composition, and an evaluation of the extent to which such variability reflects changing environment conditions
3) a direct test of the hypothesis that SE Tasmanian bays are the sole nursery area for Jackass Morwong
4) an evaluation of the likelihood of more than one spawning area/migration route for southern Bluefin Tuna.

Northern shark tagging study
In 1982, CSIRO applied to the Fishing Industry Research Trust Account for funding of a joint biological investigation of northern Australian pelagic fish stocks. At that time these stocks supported a Taiwanese surface gill-net fishery based on sharks, tunas and Spanish mackerel.
During the 1970's...
