Transitional fishery: a new resource for global nutritional food and medicinal security

Abstract

Sea and river junctions form lagoon, sites become largely marshy land with fresh water at upper approaching river reach and brackish water towards sea. Such bays are plentiful in numbers and visited by aquatic birds during the winter seasons. Previous studies established vast possibility of harvesting biological nitrogen (N) and phosphorus (P) through aquatic bird droppings viz Guano. The vast sizes and number of such sites have huge potential for fishery with differing in quality characters which is termed as transitional fishery in the present study. Objective of the present study was to bring impetus in this new category of fishery with scientific management so as to make the venture highly efficient and responsive, and enable harnessing plentiful benefits of nutritional food and medicinal security. The transitional fishery was considered as ecosystems and various networks of ecology of land, vegetation, fish and aquatic birds were brought in a band for managing it in new pattern. Ecological lessons were hypothesized and validated by results on fishery on lagoons available in literatures. First innovative lesson was that fish adopt site in North East direction of fresh water stream, as also corroborated by honey bee comb sites on N-E side of any circular water tank’s supporting posts. The second innovative fact was to transformed terrestrial land as sites for growing highly palatable nitrogen rich organic feed for fishery. Thus, colonization and feeding become conclusive approach, as supported by past researches, as guide to fishery scientist to move steps ahead in harnessing productivity of lagoons. Thus, fresh and marine brackish water transition zones become vast resources for countries to derive prosperity and employment generations. The innovative fishery feed will be usable for other types of fisheries ie fresh water fishery as well as marine fishery.
