Techniques for seed production of freshwater fish

 

Background

In the Mekong Delta of Vietnam, farming of freshwater fish is one of the leading aquaculture industries which significantly contribute to the country economy. Thus seed production has to support the farming with sufficient numbers of seed required for the grow-out farming. Recently, many aquaculture companies need more well-trained technicians for their seed production. This course is designed to train technicians for the hand-on techniques in seed production of some freshwater fish species. The aims of this course are to provide learners with basic knowledge in seed production of freshwater fish, including brood-stock selection and rearing, induced spawning techniques, fertilizing techniques, incubating techniques, rearing techniques from fry to fingerling stage, and seed transportation. The course is also to equip learners on how to evaluate and improve seed quality.  

 

Learning outcome

-          Learners will be improved in their knowledge in seed production

-          They are able to conduct seed production at their farms, from brood-stock selection to fingerling rearing stages, and seed transportation

-          They are also able to evaluate and improve seed quality

 

Lectures – Three days (7 hours every day) – Classroom

1.      Basic knowledge on seed production of freshwater fish

2.      Brood-stock rearing: principles and practices

3.      Induced spawning: hormone injection and non-hormone methods

7.      Seed quality: current and measures for improvement

Practical –  Three days (8 hours every day) – Hatchery

- Practice on artificial breeding of 2 catfish species:

1- Redtail catfish (Hemibagrus wyckioides): selection of breeders, hormone injection, spawning, fertilization, incubation, hatching

2- Catfish (Hemibagrus nemurus): selection of breeders, hormone injection, spawning, fertilization, incubation, hatching   

Final report including business plan: each trainee is required to prepare a report on what they practise at the hatchery – The length of the report may vary according ly but should not be over 10 pages.

Presentation of results by the group of trainees (Seminar Room)
