FEEDING FREQUENCY IN PACAMÃ LARVICULTURE

Scophthalmus maximus L. larviculture

The aerobic bacterial flora in the gut of turbot larvae and their influence on larval survival was examined. Two turbot experiments were run with six replicates each time. Large variation, from 0% up to 44%, was observed in the survival percentage of turbot larvae. There was no correlation between the number of bacteria present in the gut of turbot larvae and the larval survival rate. During bo...

Observations on feeding and biochemical characteristics to improve larviculture of Robsonella fontaniana (Cephalopoda: Octopodidae)

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...

Application of immunostimulants in larviculture: Feasibility and challenges

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...

Micro worm, culture method and its application in ornamental larviculture

In the culture of freshwater and saltwater aquatic species, feeding is one of the most challenging stages. During this period of life, larvae are very sensitive and many of them need special food to meet their needs, if the food does not meet the needs of larvae in terms of nutrient composition and physical characteristics such as size and shape, the survival and growth of the larvae will be se...
