1. FISH SEED CERTIFICATION AND QUARANTINE PROCEDURES

2. Freshwater aquaculture contribution to the total aquaculture more than 50 percent production.
Source of seeds -wild resources, hatcheries , import from other countries.
Induced breeding-main method of seed production.
Wild collected seeds are mainly used for maintaining the quality of broodstocks.

3. HATCHERY MANAGEMENT Hatchery management: 1) Single species or
2) Multi-species.
Broodstocks are kept separately by species
or together as mixed species.
Broodstock results in better breeding responses and increased fecundity, fertilization, hatching and larval survival rates and more viable fish seed.

4. The broodstock management process can be divided into
(a) Pre-spawning process .
(b) Post-spawning process.
Pre-spawning process
-includes procedures for broodstock selection and procurement, maintenance, maturation, acclimatization, spawning and hatching.

5. Post-spawning process
-facility maintenance,
-water quality management,
-broodstock handling;
-washing,
-selection,
-holding and transfer/transport of spawn,
-rearing of spawn,
-maintenance,
-health management,
-assessment of condition,
-selection and risk assessment for stocking,
-documentation and record keeping.

6. QUARANTINE
Quarantine -a closed holding area where brood fish are kept in individual tanks until the results of screening for known diseases or disorders are known.
Kept some distance from the hatchery.
Improvement of domesticated broodstock -genetic improvement programme (GIFT)

7. GIFT results in selection for desirable traits, Stocks with better traits (colour, growth) or are free from, or suspected to be resistant or tolerant to, specific conditions or pathogens.

8. FISH SEED QUALITY ASSURANCE
Poor quality seed-major constraint.
As per “Aquatic Seed Management” definition of the Ministry of Agriculture, fish breeders should obtain the broodstock from one of the centres established under the National Aquatic Bred and Wild Seed System (NABWSS), which includes genetic breeding center (GBC), wild variety collection center (WVCC), wild/bred variety amplifier (WBVA), exotic species centers (ESC) and seed quality inspection centers (SQIC).

9. Quality criteria includes -age and uniformity of size in terms of weight and length (Indonesia, Thailand), -growth performance, survival and percentage of deformities (Vietnam) -body shape and behaviour (Sri Lanka.)

10. -causative agents for severe mortalities
Ichthyopthirius sp. (ich disease),
Trichodina spp.,
Ichthyobodo spp.,
Lernaea spp.,
Myxobolus spp.,Dactylogyrus spp.-affect the gills and cause heavy mortalities in Catla catla.

11. Using the same brooders more than once in a breeding season causes deterioration of larval quality, mortality and larval deformity.
Preserving the genetic quality of broodstock assures high quality seed.
