Samdrupjongkhar farmers trained in advanced fish production

 The National Research Centre for Aquaculture (NRCA), Gelegphu recently conducted five day training course on advanced fish production technology for 14 farmers, comprising of 3 female and 11 male participants from Samdrup Jongkhar Dzongkhag. The training was conducted from 17th – 22nd October, 2017 at NRCA. The participants, who were among the most progressive farmers, were lead by Mr. Changchung, Fisheries Focal Person of Samdrup Jongkhar Dzongkhag. The training was funded by Dzongkhag Livestock Sector, Samdrup Jongkhar.

During the course of training, the farmers were particularly trained on the important aspects of fish farming, particularly the followings:

a)    Pre-stocking management: The farmers were explained on importance of drying, liming and fertilization of the fish ponds. During the interaction, it was noted that most of the farmers were not aware about the importance of liming and fertilization and also about the dosage. The farmers were also made to realize the importance of plankton development in pond ecosystem prior to the release of fingerlings. A practical class on pre-stocking management was also arranged, involving cleaning of fish pond, liming, and fertilization. The farmers were made to calculate the area of the pond, accordingly determine the requirement of lime and manure; and apply as they were taught during theory class.

b)    Stocking management: Concept of polyculture was explained to the farmers with importance of stocking density and species combination as they greatly affect the fish production. In addition, farmers were informed about the stunted fingerlings and its advantages over ordinary fingerlings, including the season during which the advanced fingerlings will be available at NRCA. After learning the advantages, most expressed their desire to adopt fish farming with advanced fingerlings. The farmers were also given practical demonstration on acclimatization of fish prior to their release in fish ponds.

 c)    Post stocking management: With regard to post stocking management, the farmers were taught on the importance of supplementary feeding and regular manuring. More emphasis was given in maintenance of optimum of productivity through application of manures, as this is most critical part in enhancing the productivity level of fish pond. Practical demonstration on usage of Secchi disc and application of elbow method for determination of planktonic productivity in fish pond was also demonstrated. In addition, they were also taught on djustment of regular manuring on basis of result from Secchi disc and elbow method reading. During interaction, two cases of fish mortality in ponds were associated with excessive fertilization, and the dosage applied was around 10-17 folds than what is required normally. The farmers, was also given practical training on drag netting of fish and formulation and feeding of fish feed. Harvesting methods such as partial and complete harvesting was also explained and were also taught about post harvest handling of fish.

 d)    Record keeping: As record keeping is very important part of any commercial venture, farmers were given ideas management of investment records and determination of unit cost of production and selling price.

On final day of training, as per the farmer’s comments, it was noted that the training proved to be useful in enhancing their skills and knowledge on fish farming. They were also eager to implement the newly acquired techniques in fish farming as soon as they reach their home. A day long field visit was also arranged to National Poultry Research Centre (NPRC), Sarpang; Agriculture Research and Development Centre (ARDC), Bhur; Integrated Fish cum Piggery Farm at Sisty, Sarpang and Southern Seedling, a private farm at Bhur.
