Block-Week for CNR B Sc. Animal Science (Year 1) Students successfully conducted…

Since the introduction of aquaculture in the syllabus for the students of Bachelors in Science degree in CNR, NRDCA have been providing the students with on farm classes in the form of block-week. The training includes both theoretical as well as practical sessions.As is the practice every year, this year also a class of twenty one students were trained on different aspects of management on aquaculture. A week long session consisted of theory classes in the morning and practical sessions in the afternoon. This block-week was held from 8th of September to 13th of September 2017.


Day 1

The program kick started with theory class on fish propagation. The class was briefed on the importance of fish breeding and how they are categorized. During the practical session in the afternoon, the trainees were shown the different structures of a fish pond. The day ended with another practical session on liming and manuring a fish pond.

Day 2

On the second day, a theory class on the important aspects of live fish transportation was conducted. The trainees were also taught the fish health and disease management. The practical session was conducted on fingerling packaging and transportation.

Day 3

The trainees were briefed on the different anatomies of fish in the morning of the third day. Theory session on identification of six different species of cultivable carps was also conducted. During practical, demonstration of net dragging and artificial propagation of fish was carried out.

Day 4

Day four started with theory session on the advantages of integration of aquaculture with other livestock. The afternoon session consisted of practical class on feed formulation demonstration and feeding.

Day 5

On the final day theory class on quality assurance of fresh fish was conducted. The day ended with a field visit to the farm of one of the progressive fish farmers in Sisty under Singye geog under Sarpang dzongkhag.


Since College of Natural Resources does not currently have available the expertise or the facilities to enable the trainees to learn fully on-campusthe aspects of aquaculture, National Research & Development Centre has been providing on-campus as well as on-farm classes. Including the latest batch, NRDCA has received and trained four batches of trainees till date.

Hands-on training of government extension officials in freshwater pond fish culture technology…

Twenty three field staff(s) from eight Dzongkhag(s) namely Chhukha, Pemagatshel, Punakha, RCA-Samdrupjongkhar, Tashigang, Tsirang, Wangdue and Zhemgang underwent second phase week long hands-on training on freshwater fish culture. The training was conducted from 10th April to 16th April, 2017 in Gelephu by the National Research Centre for Aquaculture (NRCA).

The training was conducted with the following objectives:

  • Acquaint the participants with the principles of pond fish farming;
  • Disseminate lessons on Aquaculture Best Management Practices;
  • Acquaint the participants with the fundamentals of fingerling requisitioning and species combination for polyculture;
  • Acquaint the participants with the basic techniques of conducting feasibility studies to establish fish culture systems;
  • Empower the participants with the skill necessary to guide the establishment of standard fish farm infrastructure;
  • Acquaint the participants with the procedure of requisitioning aquaculture support services;

The training intended to reinforce the technical competence of the extension officials to guide fish farmers successfully produce fish in earthen ponds. Among other things, basic knowledge and idea on fish identification techniques and fish farm management techniques were imparted to the officials. Practical sessions were also conducted on the formulation of simple fish feed using locally available ingredients, commercial feed dispensation, pond component identification and preparation, fish identification through typical taxonomical traits,  fingerling quality inspection, packaging, transporting and stocking. The participants also visited the Golden Mahaseer (Tor putitora) Conservation Centre (GMCC) to acquaint themselves with sub-tropical fish diversity that the NRCA has started to curate.The fund for the training was provided by Government of India’s Project under Department of Livestock of Ministry of Agriculture and Forests.

Samdrupjongkhar farmers trained in advanced fish production technology…

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.
