In this respect, fish are reliant on passive immunostimulation from maternal antibodies, and this mechanism has been shown in tilapias (Mor et al, 1990; Sin et al 1994). In any given species, size rather than age seems to be the most critical determinant of the development of immunity. For example, in salmonids, memory-dependent immunity has been achieved for sizes > 0.26g (8 weeks of age), whe...

At present, the production of merobenthic octopuses with a post-eclosion planktonic phase is a great challenge for global aquaculture. So far, juveniles from only four species have been reported to have been obtained under controlled rearing conditions: Octopus vulgaris, Octopus joubini, Enteroctopus dofleini and Robsonella fontaniana, the only Chilean species. Robsonella fontaniana (Orbigny, 1...

The ballan wrasse, Labrus bergylta, Ascanius 1767, is a promising species for use as a cleaning fish for salmon farms in the northern hemisphere, due to their cleaning behaviour and their ability to remain active at low temperatures [1]. It is commonly agreed that a potential increase in the demand for ballan wrasse from the industry must be met by future aquaculture production of this species....

In aquaculture, more than in other animal productions, prevention is a key issue in health management. The risk of diseases increases with the intensification of the production and can be controlled mainly through the implementation of sanitary or medical prophylactic programs. Sanitary prophylaxis relates to hygienic rules, cleaning and disinfection procedures, water treatment, but also good f...

Shrimp grow-out and hatchery systems are being affected by bacterial disease particularly Vibrios. The use of chemotherapeutic agents in aquaculture practices has to lead the development resistance among aquatic bacteria. Thus, health management becomes major importance aquaculture. Under this situation, progressing bio-inhibitors from marine resources most appropriate be considered against pat...

Clownfish is one of the most demanding-marine ornamental fish. Due to increased demand clownfish, wild clownfish catch has also been increasing, until reaching overexploitation condition. One way preserve existence this fish species and sustainably fulfil market by conducting a culture technique with advanced application using recirculating-aquaculture system, specifically larviculture. Thereby...
