Solution to Over-fishing => Control on by-catch By-catch refers to fish or other marine species, that are inadvertently caught, while fishing for a specific target species. Controls include: 1. The banning of fishing, in areas where by-catch is very high. This can be permanent or seasonal. This practice is common in bottom-trawl fisheries. In some cases, the relocation of fishing vessels are necessary, when by-catch becomes an issue. 2. The use of alternative fishing equipment can be used. Modifying existing equipment may also be done to ensure that unwanted species are not caught. Examples: Nets with larger mesh sizes By-catch Reduction Devices (BRDs) Turtle Excluder Devices In some cases, by-catch are not released but are sold as food (in Asia and Africa). It may also be turned into fish hydrolysate (minced/ground up fish carcasses) which in added to soil in organic agriculture.
