(a) Broodstock management, controlled breeding and seed production:

Asian seabass - Lates calcarifer 
  • Technology for captive land based broodstock of Asian seabass (150 nos.) of F1 and F2 generations has been standardized and maintained in the broodstock holding facilities.
  • Technology package for natural and hormone induced captive maturation and breeding were developed
  • Year round breeding (outside the natural spawning season) with environmental manipulation has been achieved.
  • Effective fertilization (up to 90%) and hatching up to 95% have been achieved.
  • Seed production technology was transferred through trainings and demonstrations to State department officials, entrepreneurs and hatchery operators.
  • CIBA hatchery produced hatchlings were supplied to commercial hatcheries like M/s. Periyar Integrated Fish Farm, Chennai, and using the technology of CIBA, the hatchery operator achieved survival rate of 58% for 30 days rearing.
  • Knowledge of captive maturation and controlled breeding of Asian seabass was imparted to entrepreneurs and academicians through Winter School of 21 days duration.
  • Larval rearing protocols of Asian seabass standardized and survival rate up to 50% for 30 days rearing was achieved.
  • Technology for year round maintenance and intensive culture of essential live feeds like rotifer and algae developed.
  • Seeds supplied to farmers, entrepreneurs, state departments and universities for the development of Asian seabass aquaculture

Grey mullet Mugil cephalus 

  • Protocols for land based captive broodstock management of Mugil cephalus standardized
  • About 130 nos. of broodstock in the size range of 0.75 – 1.5 kg were maintained in the holding facilities
  • Successful maturation of captive male broodstock was achieved through hormonal intervention.
  • The hormonal dose for controlled breeding through was standardized.
  • One successful spawning of grey mullet took place and larvae were reared to juveniles.

Broodstock development of other brackishwater fishes 

  • Broodstock of milk fish Chanos chanos has been developed from 2004 and 4+ years old stock are maintained (32 nos.) in the holding facilities. For the first time in India, male maturation of milk fish with oozing milt was observed in the captive broodstock.
  • Captive stock of ornamental fishes Scatophagus argus and moon fish, Monodactylus argentius were maintained in the broodstock holding facilities for controlled breeding trials.
  • Andaman Tilapia Oreochromis urolepis brought from Andaman islands has been developed as broodstock
  • NAIP Project for breeding and seed production of Cobia Rachycentron canadum has been taken up with CIBA as a consortium partner, and broodstock is being developed.

Ornamental fish

(b) Nursery rearing and culture

  • Nursery rearing of seabass fry of 1.0 cm stocked in varying densities of 200 to 2000 no./m3 and fed with formulated diet registered  survival rate of 43 to 78% in nursery tanks, 81-90% in hapas and 23-74% in hatchery tanks.
  • Grow-out culture of seabass was undertaken in Tamil Nadu, Andhra Pradesh and West Bengal under varying densities and encouraging results were noticed.
  • Pond culture of seabass as polyculture with carps was successfully demonstrated to a farmer in Ganapavaram, Bhimavaranm, Andhra Pradesh with seabass production of 3.12 t/ha and 1.43 t of carp.
  • Demonstration of seabass culture has been taken up in the East Kolkata wetland ecosystem with initial stocking density of 36000/ha. The stock is maintained for growth studies under nursery rearing system and will be stocked in other ponds for grow out culture under extensive farming system.
  • To demonstrate the techno economic viability of Asian seabass farming in pond culture ecosystem NFDB funded Demonstration Project has been taken up in Andhra Pradesh, Tamil Nadu and Maharashtra.
  • A comparative evaluation of tilapia from Andaman Oreochromis urolepis and that from the mainland Oreochromis mossambicus showed that the performance of O. urolepis was superior in seawater condition.
  • Culture of pearlspot Etroplus suratensis and milk fish C. chanos have been taken up at KRC ponds and in farmer’s pond. Cage culture of peralspot is in progress at Nagayalanka in Andhra Pradesh.
