Abstract/ Executive Summary:

Preliminary results on possibility of polyculture of small indigenous fish species and initiation of social fishery concept in Bangladesh have been discussed. It has been found that small fishes may create considerable outcome if they are cultured properly. The unutilized ponds and roadside ditches may be brought under productive utilization as well as a large group of people in the rural areas could be engaged in this type of culture practice. In the present study, three species of small fishes, viz., Colisa fasciatus (Bloch & Schneider), Puntius stigma ( Hamilton-Buchanan) and Rohtee cotio (Hamilton-Buchanan) were cultured and the production of these fishes varied between 0.38 and 0.45 mtons, 0.47 and 0.63 mtons and 0.53 and 0.69 mtonslha/year, respectively in a single culture period, probably depending on the stocking ratio. Both male and female poor folks could be engaged in the social fishery; however, females could get importance since they get easy entrance in almost all the rural households

Program Area: Socio-economic and Policy

Commodity: Fish

Objectives:

To save the small indigenous fish from the verge of extinction and also to show a source of income generation for the rural people.

Methodology:

Three species of indigenous small fishes, Viz., Dhela (Rohtee cotio), Punti (Puntius stigma) and Khalisha (Colisa fasciatus)were selected for the present investigation. Efforts were made to establish the culture practice and management procedure for these small fishes. Sites at several locations were considered in order to select the project site, in and around the Faridpur district. Two principal stations were selected, each of which controls separate field stations. The first station was at Faridpur district which controls two field stations, one at Boalmari under Madhukhali Thana, while the second station was at Rajbari district that controls two field stations, one at Rajbari Sadar Thana and the other at Baliakhandi Thana. Following waterbodies were considered for the present study: (i) roadside ditches, (ii) derelict ponds of private owners and (iii) ponds not used for fish culture or other purposes. These waterbodies were selected for easy communication and easy access during present study. The clay soil of the ponds and ditches were re excavated to 0.8 to 1.0 m in depth covering an area of 500 m² on an average. This ensures a uniform depth of water area. At each site, at least one waterbody was provided with an adjacent breeding area. The breeding area was somewhat elevated. On the breeding ground, vegetation was allowed to grow naturally. Although, the procedure advocated by UNICEF was followed, prior to the application of organic manure and inorganic fertilizers, soil characteristics of waterbodies were examined. Usually all the ponds and ditches in the same locality were supplied with the same dosage of fertilizers and manure. The stacking of fish species took place at the end of May, 1995, within 8 to 10 days after filling the waterbodies. Fish species for the present study were collected from fish farmer's pond, seed collection pits and fish fry production center as and when possible. The stocking rate and density were calculated considering the expected growth and production of Khalisha, Punti and Dhela. Initial weight and density of stocked fry of these fishes were 2.0- 2.0 g, 1.5- 2.4 g and i.O- 3.0 g/m², respectively. The selected fish species were cultured for a period of eight months, starting from April to November 1995.

Achievement/Findings:

The results of the present experiment revealed that the unused waterbodies can be made to produce a large amount of small fish. It has been found that, the production of Khalisha ranged between 345 and 413 kg, while the production of Punti and Dhela were 429- 576 kg and 480- 624 kg/hal crop/yr, respectively. The present rate of production, however, is lower in comparison with the production level reported by Jhingran and Lin but it is assumed that the current rate of production could be raised to a much higher level following modern aquaculture technology. The present work is exploratory in nature and the authors consider that this was the beginning of a new vista on this line, as there are many things to do to enhance production per unit area. Moreover, in case of small fish culture activities poorfolks of the rural area may be involved in a befitting manner, and thus the social fishery may be developed like that of social forestry. This will benefit the society in two ways, the rural poorflok specially the females will get a source of earning and on other hand, the rural as well as urban poorfolks will get adequate animal protein at low cost and unused waterbodies will be profitability utilized. Culture and management of small indigenous fish species as a sustainable social fishery practice has a great possibility for expansion in future. Each and every waterbody or a cluster of waterbodies having deeper areas which retain water in dry season but do not submerge in rainy season may serve as seed banks, since the adult brood stock could be kept as a source of seeds for future use in them . In this way availability of fish seeds in large number could easily be ensured.
