Development of predictive model of cod-end selectivity
This project develops a predictive model of cod-end selection so that the selectivity of commercially used cod-ends fished in commercial conditions can be predicted.
This project will be achieved by investigating and including the following influences in the model:
1) netting materials made from thicker and stiffer twines
2) the dynamic effects of the interaction of sea state, fishing vessel, trawl gear and cod-end
3) fish morphology and fish escape behaviour.
Progress to Date
A statistical and a deterministic model of the catch shape in the cod-end are in progress.
The specialised instrument to measure the forces required to open a piece of netting were developed.
Experiments measuring the forces required to open panels of netting were carried out.
