“…The specific growth rate was calculated from the slope of the linear regression of log-transformed dry weight against age (Albentosa et al, 1997). The final biomass was calculated with the dry weight and the larval density was obtained at the end as described by (Cahu et al, 1998).…”

Enrichment has shown considerable influence on the population growth, reproduction and individual growth of rotifer (Brachionus plicatilis Müller, 1786) and its utility on the clownfish larvae (Amphiprion ocellaris Cuvier 1830). Using the culture medium of microalgae (Nannochloropsis salina D.J. Hibberd 1981) as the control, rotifers were enriched by dissolving in S-presso (for short term enrichment) or L-carnitine supplements. The study was conducted in three replicates for five and 10 days of batch culture. On day-4, the population density of rotifers exposed to 1, 10 and 100 mg l -1 L-carnitine was significantly increased (p<0.001) by 43, 39 and 54%, respectively, compared to the control. The population density in these three treatments also increased on day-2, day-3 and day-5 compared to the 1000 mg L -1 treatment (p<0.05) and control (p<0.05). The body length (p<0.001) and width (p<0.05) were significantly reduced in the 1000 mgL -1 treatment compared to the control. The mean values of total unsaturated fatty acids (PUFA's, HUFA's and n-3 fatty acids) and the ratio of n-3/n-6, DHA/EPA, EPA/AA were significantly higher (p<0.05) in the rotifers enriched with L-carnitine compared to S-presso and algae. Larvae fed using rotifer enriched with Lcarnitine gained the maximum growth (65.7±1 mg), followed by those enriched with S-presso (42.2±0 mg). In L-carnitine treatment, metamorphosis took only 9 days, followed by the control. In L-carnitine and S-presso units, the clownfish larvae took only three days for the first pigmentation compared to four days in N. salina (control) and 10 days with S-presso. Rotifers enriched with L-carnitine showed the highest survival rate (70 %) of the clownfish followed by the control (68%) and S-presso (52%). The results suggested that L-carnitine could be a positive factor to enhance the rotifer production and also its utilization in clownfish larval culture.

Furthermore, a number of successful trials have demonstrated the feasibility of rearing this bivalve in different European countries (Walne, 1976;Breber, 1985;Pastore et al, 1996) using different culture techniques in the sea as well as in coastal lagoons (Chessa et al, 1998(Chessa et al, , 2005Pais et al, 2006b;Serdar et al, 2007).…”

Shellfish aquaculture is a widespread activity in the Italian peninsula. However, only two bivalve species are mainly cultured along the coastline of that country: the Mediterranean mussel Mytilus galloprovincialis and the Manila clam Venerupis philippinarum (Ruditapes philippinarum). By contrast, just a few other mollusc species of commercial interest are scarcely reared at a small-scale level.After analysing the current status of Italian shellfish production, this paper reports and discusses the potential for culturing several different invertebrate species [i.e., the European flat oyster Ostrea edulis, the grooved carpet shell Venerupis decussata (Ruditapes decussatus), the razor clams Ensis minor and Solen marginatus, the cephalopod Octopus vulgaris, and the purple sea urchin Paracentrotus lividus] in this country.In addition, a detailed overview of the progress made in aquacultural techniques for these species in the Mediterranean basin is presented, highlighting the most relevant bottlenecks and the way forward to shift from the experimental to the aquaculture phase. Finally, an outlook of the main economic and environmental benefits arising from these shellfish culture practices is also given.

Pinctada maxima is a filter feeder organism obtaining food particles by filtration from water suspension. Filtration and ingestion rate of a large number of benthic filter feeders in a variety of coastal environment have been known influenced by current velocity. The purposes of this study were to examine the effects of current velocity on filtration and ingestion rate of pearl oyster P. maxima and to determine the best current velocity. Randomized Block Design was used in this experiment with four current treatments of 8, 16, 24, and 32 cm s -1 . The results of this experiment demonstrated that current velocity has a marked effect on filtration rate of P. maxima and that this species follows the general pattern of response observed for other bivalves. Different velocity affected filtration and ingestion rate in pearl oyster P. maxima. It was gradual decline in the suspension feeding with increasing velocity. Filtration rate of bivalves with siphons facing into the current, were directly inhibited by hydrodynamic effects on the functioning of the bivalves pump. At increasing current velocity, pressures applied to the inhalant and exhalant aperture facing into the flow would result in higher pressures than that of produced by the ciliary pump, resulting in reduced filtration rate. The highest filtration and ingestion rate in this experiment were obtained at velocity of 8 cm s -1 that achieved 3.409±0.485 l/h and 37.91±1.27 (x10 7 ) cells/h, respectively.
