Enhance Purse Seine Vessels and Gear Efficiency – Effective Purse Seine Operation

In review of papers on purse seine gear and technology, the author proposed that purse seine efficiency can be defined by an increasing ability to land a given quantity of tuna in less time, or an increased catch potential in a given time period (one year). This increasing efficiency consists of increasing actual fishing time, minimizing in port turnarounds, increasing the speed with which tuna can be caught, loaded and frozen onboard and decreasing overhead costs. It was proposed that purse seine efficiency can be achieved by:

I. Adequate fishing power large deep net designed for fast pursing

1. full complement of electronics for tuna school assessment (high and low frequency sonar, scientific grade echo sounders, (more…)
