Giant Tiger Prawn
The Panaceas Monodon Fabric us commonly known as the giant tiger prawn,leader prawn, panda prawn and blue tiger prawn live in estuarine waters, in sea grass beds and mangrove areas. From these nursery areas, the juvenile prawns migrate to deeper coastal waters inhabiting mud, silt and sand substrates. They usually live in less than 30m of water, but have been caught in waters as deep as 110m. Life HistoryMost of the information on life history is based on research into commercial farming of the species. However, it is known that in the wild, spawning is initiated by rising water temperatures. In warmer tropical waters there is an extended spawning period, due to spawning occurring mainly in deeper coastal waters.
During hatchery conditions, females spawn at night, under optimum water temperatures, which range between 28 and 30 degrees Centigrade. The eggs hatch after 10 to 14 hours. The larvae grow through several development stages in the next 10 days. The eggs larval and post larval prawns are plank tonic for the first 2 weeks of life. In the wild, the larvae move on coastal currents to nursery areas in shallow embayment and mangrove fringed estuaries where they settle onto the substrate. They remain in this habitat until about 80mm long.
Giant tiger prawns have also been recorded up to 150g in weight, but in farming operations they are generally harvested at between 100mm and 130mm total in length, weighing between 20g and 30g. In commercial fishery, giant tiger prawns are combined with other tiger prawns in catches, so there are no separate catch figures recorded for them. 90% of wild caught spawning females are sold to hatcheries as brood stock.
Spawning- The best monetary return is for females in spawning condition. These egg bearing females are placed in spawning tanks on arrival, while the blank females and males are kept in maturation tanks at the hatchery until required. In farming operations, ponds are prepared to ensure phytoplankton blooms prior to and during stocking by feeding prawns with commercial food pellets during the pond grow out stage.
