Large-Scale Hatchery Technology
MAC is carrying out R&D in these areas to develop large-scale hatchery technology:
Culture systems and operations for large-scale commercial production of fry at all the hatchery stages:
- egg collection and hatching
- live larval feed production
- Seawater re-use technology
- Developing optimal hatchery conditions and good hatchery practices
- Live fish transportation methods
- Hatchery fish health, feed and nutritional requirements
- New or novel species - to study the potential of high-value fish species for hatchery technology development
MAC also carries out research and development for these other hatchery-related technologies:
|Type Of Technology
|Fish reproduction technology
||To close the reproductive cycles of key marine food fish species
|Live fish larval food production
||To improve the nutritional quality of live larval food, develop and improve culture technique for common live food micro-organisms such as algae and rotifers, and to identify other alternative live food
|Inert larval feed supplements
||To develop formulated larval feeds that can supplement or replace expensive live larval food
||To improve brooder fish quality
|Fish biotechnology and other upstream molecular applications
||Genetic selection to facilitate fish breeding, development of fish vaccines and diagnostic kits.
Large-Scale Deep Netcage Farming Technology
MAC also promotes large-scale deep netcage fish farming of tropical food fish species:
- asian seabass (Lates calcarifer)
- trevallys (Caranx spp)
- cobia or black kingfish (Rachycentron canadum)
- snappers (Lutjanus spp)
- pompano (Trachinotus blochii)
MAC aims to maximise production rates, develop feeding strategies and optimise feed utilization for effective production of these tropical marine food fish.
Complex Mooring System in Deep Netcage Fish Farm
A deep netcage fish farm has a complex mooring system that is anchored to the sea bed. This mooring system can withstand the swift currents found in open waters.
Heavy duty high density polyethylene (HDPE) floating collars of 12.5 metres or more in diameter, and smaller squares are fitted into the grids of the mooring system. Cage nets with a depth of 6 to more than 8 metres are secured to these frames. The deep cages allow stocking of more fish per square metre compared to the more traditional shallow coastal cages.
Skilled workers operate the deep netcage fish farm. These farms also have automatic fish feeding and counting, and mechanized harvesting.
