Capture Technology and Operations in Marine Fisheries


Medwin Gale


Marine Capture Fisheries is an extensive and exhaustive foray into the world of fisheries within the context of marine based ecosystems.
            In capture fisheries, the wild populations are simply harvested from the natural waters with little human intervention in modifying the ecosystem i.e. hunting. Example: marine fishery. On the other hand, in a culture fishery, the whole operation is based on captive stocks with a high degree of effective human control over the water quality and other habitat variables. Example: Culture of fish and shell-fish in ponds. When the fish harvest in an open water system depends solely or mainly on artificial recruitment (stocking), it is generally referred to as culturebased fisheries. Culture-based fishery is the most common method of enhancing the fish production being followed in some inland water bodies in India.

Fishing techniques are methods for catching fish. The term may also be applied to methods for catching other aquatic animals such as mollusks (shellfish. squid. octopus) and edible marine invertebrates. Fishing techniques include hand gathering. spearfishing. netting. angling and trapping. Recreational. commercial and artisanal fishers use different techniques. and also. sometimes. the same techniques. Recreational fishers fish for pleasure or sport. while commercial fishers fish for profit. Artisanal fishers use traditional. low-tech methods. for survival in third-world countries. and as a cultural heritage in other countries. Mostly. recreational fishers use angling methods and commercial fishers use netting methods.

Capture fisheries is intended for catching fishes and also prawns, lobsters, crabs, sea-cucumbers, shales, pearl oysters, edible bivalve and copious other organisms of other than fishes etc. Premitive human being were acquinted with capture fishery centuries passed for him to observe and understand for the possibilities of culturing fish. Then also he depended mostly on the culture of fishes with parental care. Later, he tried to collect the fingerlings in canals, distribution canals. In the earlier days, the mixture of carnivore fish fingerlings and carp fish fingerlings were stocked together in tanks. Later, they were segregated and stocked selecting the required vaiety. Capture of fishes can be broadly divided in to two types; a) Capture by Human effort b) Capture by observing the behavioural pattern of Fishes.

The various factors contributing to the growth of this industry has also been explored and in a compendious manner, it provides an exhaustive manual dealing with this industry.
