Northern pelagic fish stock research

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...

Objectives

1. Are banana prawns reproducing in numbers to maintain population level? Predict catch size. Location.
2. Determine age & growth rates for various stocks. Tides model to calculate drift & diffusion rates.
3. Taxonomic references to compare larvae from wild. Population ecology & feeding relationships
