Sport Fishing Techniques

Gill nets

Gill-nets are the dominant gear in the Indian Ocean. Gill-nets are used in artisanal and semi-industrial fisheries, contributing to 30-40% of the total catch. The net design is comprised of continuous panels of uniform mesh size, aimed to trap fish behind the gills. The International Sustainable Seafood Foundation (ISSF) notes that rates of sharks and turtle by-catch in Indian Ocean gill-net fisheries are high..

Tackle & Baits

Most Jacks are fairly small and are caught on the full range of light tackle by anglers seeking other game. If you target larger Jacks, say 10 pounds or more, sturdy spinning, baitcasting and fly tackle should be used, with lines no less than 8-pound test
