Reproduction in the Tropical Rock Lobster Panulirus ornatus in Captivity

摘要: The Australian spiny lobster fishery is Australia's most economically valuable fishery, presently worth around $450 million per annum (Anon., 2008a). However, while many are currently well managed, fisheries at their maximum sustainable capacity whilst demand for continues to increase (Jones, 2009a). Globally, catch rates have stabilised or even declined since 2002 (FAO, 2007; 2009). Furthermore, due anthropogenic perturbations, wild production may actually drop significantly as highlighted by recent projections western rock and marked decreases in unit effort (CPUE) species 2008b; FAO, only real potential significant growth appears be through aquaculture. Internationally, aquaculture date has consisted of capturing juvenile seed stock on-growing market size 2009b). the long-term viability sustainability depends on closing life cycle developing an viable method raising lobsters from eggs (Grove-Jones et al., 2002). The ornate (Panulirus ornatus) been identified having clear commercial potential, largely its abbreviated history compared other 2002; George, 2005). More specifically, relatively short larval phase (4 months) fast rate make it a suitable candidate if techniques technologies, consistently produce large numbers juveniles eggs, developed. A Fisheries Research Development Corporation (FRDC) commissioned review 2002) stated that development puerulus technology would 5+ year prospect, which should addressed three discrete phases effectively achieve commercialisation Australia (see Chapter II). The experiments carried out part this study address I specified Grove-Jones al. (2002). This work fills important knowledge gaps previously unknown species, brief, major findings include: 1. control breeding, gonad development, moulting egg extrusion though photoperiodic water temperature manipulation. In particular, lengthening photoperiod cue breeding species. 2. optimal incubation defined model predict hatch timing developmental period embryos when incubated range temperatures. 3. Techniques quantitatively assess phyllosoma quality hatch, including ten minute salinity stress test. 4. Larval husbandry high survival stage V. These towards hatchery P. ornatus. Ultimately, these fundamental successful culture. Results studies made contribution culture ornatus within Australia. they formed foundation continuing area rearing resulted completion Panulirus captive culture.
