Abstract

West Bengal contains richest source of freshwater indigenous fishes having tremendous potential as ornamental fishes. Some of the indigenous ornamental fishes are Notopterus notopterus, Notopterus chitala, Ompok pabda, Danio devario, Brachydanio rerio, Mystus spp., Puntius spp., Chanda spp., Colisa spp., Pangasius sutchi, Glossogobius giuris, Nandus nandus, Heteropneustes fossilis, Anabus testudineus, Channa punctutus, Mastacembalus armatus, Rasbora rasbora, Chacca chacca, etc. Our survey in some districts of West Bengal revealed that these ornamental fishes are under threat due to indiscriminate introduction of exotic fishes, application of toxicants and pesticides and eradication of these potential fishes as weed fishes during composite fish culture or polyculture. But the fact is that huge demand remains in the international market for these fishes. This paper as an attempt to reveal that there is a great opportunity in entrepreneurship development among the unemployed person with more sustainable exploitation of the above indigenous fishes.

Abstract

A survey was undertaken in the districts of Nadia and North and South 24 Parganas with an objective to study as to how Indigenous Technical Knowledges (ITKs) are adopted by the fish farmers for controlling the diseases. It was observed that a number of ITKs have been adopted by the fish growers since time immemorial irrespective of the status of the grower be it domestic or commercial and marginal, small, medium or large. It was also observed that most of the ITKs have scientific explanation. These are adopted on the principle of "seeing in believing".

Abstract

Fish pheromones are much more studied than those of other nonmammalian vertebrates. A "pheromone" is a chemical that triggers a natural behavioral response in another member of the same species. There are alarm pheromones, food trail pheromone, sex pheromone and many other that affect behavior or physiology.

Abstract

To achieve sustainable development of beel fisheries, the role of beel users cannot he overruled. Beel users play very important role for all round development of beek. The beels are in general considered as biologically sensitive habitats of different types of fishes and also provide breeding and nursery grounds for commercially important fishes. The beels vary widely in size and offer tremendous scope for expanding both culture and capture-based fisheries. In Assam there are so many beels but their production potentiality has yet not been exploited properly. Considering the present scenario, the beel users' knowledge and utilization of information resources were studied in the present investigation. The findings of the study revealed that utilization of information sources was significantly and positively correlated with the knowledge levels of beel users for sustainable development of beel fisheries. The study further indicated that knowledge levels of beel users increased with the increase of levels of utilization of information sources in a systematic progression.

Abstract

The state West Bengal has iinmense scope for fish production hoth from inland and marine sectors for the reason that Fishermen's Co-operative Society was established in this state as early as 1918 to enhance the fish production and at the same time to imporve the quality of life of the fish farmers by organizing themselves. But, since its inception, the fish farmers arc suffering from constraints both in management and cultural aspects. So, a study was undertaken to find out the main problems that co-operatives are experiencing. Fisheries co-opcrativcs of West Bengal are well known for their contribution to the development of small-scale fisheries. The study unveiled that besides confronting with various problems the Fishermen's Cooperative Societies working in the Noth 24-Paraganas district are successfully implementing their planning at local level. Further, the Fishermen's Co-operative Societies can be one ol' the thrust areas for fisheries development if Government and other voluntary organizations give proper incentive in the functiong of the co-operatives especially in the management aspect.
