“…comm.). Exposing crustacean larvae to salinity stress is a common method to quantify competency and is based on the premise that an adverse environmental condition will elicit a response based on the animal's physiological and nutritional status (Tackaert et al 1989;Villalón 1991;Clifford 1992;Fegan 1992;Bray & Lawrence 1992;Samocha et al 1998), potentially indicating their ability to mobilise nutrients under duress (Racotta et al 2003). Therefore, salinity stress tests are effective in predicting larval competence, especially inJ.…”

A study was conducted to examine the effects of physical disturbance on Jasus edwardsii spiny lobster broodstock during ovarian recrudescence through to larval hatch. Undisturbed broodstock were held in relative isolation and subjected to minimal human disturbance, which contrasted with weekly air exposure and handling of the disturbed animals. Broodstock behavioural response, phyllosoma number, competency, and survival in culture were examined. A higher proportion of broodstock from the undisturbed treatment were active during daylight hours compared with those in the disturbed treatment. All ovigerous females in the undisturbed group produced phyllosoma larvae compared with 72.7% of animals in the disturbed treatment. Individual undisturbed females produced greater numbers of phyllosoma larvae, which in turn performed better in larval competency tests, were larger at hatch, and survived better in culture than those from disturbed females. This study demonstrated that physical disturbance altered reproductive performance and larval competency of J. edwardsii. Protocols are suggested to minimise disturbance associated with handling in crustacean broodstock.

“…If the nutritional requirements of the broodstock are met, the larvae of P. pelagicus will have high survival rate. Some of the components in broodstock diet like fatty acids (FA) can influence the fecundity, larval quality and hatching ability of several fishes and crustaceans (Racotta et al, 2003;Azra and Ikhwanuddin, 2016).…”

“…This is a big amount and must have significant ecological footprint that makes it an unsustainable practice. While many factors including broodstock condition, genetic composition and endocrinological stimulation determine the egg quality [3], broodstock nutrition is a critical factor in sexual maturation, fertility and production of high quality larvae.…”

Importance of shrimp as a high quality seafood is growing worldwide. Quantities from capture fisheries are unable to meet the human requirement. Aquaculture seeks to bridge the gap between the supply and demand but the aquaculture production is constrained by inadequate availability of high quality seed for farming. While the number of hatcheries producing seed has grown, the problem of egg quality still remains a challenge. The most important factor is broodstock nutrition. Several feeds are availability but failure of gonad maturation and fertility are quite common. This study was carried out to determine the effects of an unconventional diet in the form of sea urchin roe and a commercial feed. The two dietary treatments produced significant (P<0.005) difference in the gonad development. The gonado-somatic index (%) of the test specimens offered sea urchin roe was 10.3±0.5 while it was 7.0±1.0 in the shrimp stock provided the commercial feed. These differences are discussed in this paper.
