This paper is part of a series studies aimed at understanding the potential exploitation biomass polychaete worm Sabella spallanzanii (Gmelin, 1791), which obtained as by-product an innovative Integrated Multi-Trophic Aquaculture (IMTA) system. IMTA systems are designed according to ecosystem approach with aim reduce marine monoculture impact while further increasing production via valuable by-...

Clownfishes (or anemonefishes) form an iconic group of coral reef fishes, particularly known for their mutualistic interaction with sea anemones. They are characterized by particular life history traits, such as a complex social structure and mating system involving sequential hermaphroditism, coupled with an exceptionally long lifespan. Additionally, clownfishes are considered to be one of the...

This study was designed to evaluate the effects of astaxanthin in broodfish diets on reproductive performance, egg quality and larvae parameters clownfish (Amphirion ocellaris). Five treatments were tested with 5 levels (Carophyll Pink 10% CWS) 0, 50, 100, 150 200 mg/kg added feed. Each treatment repeated triplicate supplemental feeding trials arranged for 13 months. The results showed that the...

Amphiprion clarkii and A. nigripes were found in coral reefs of three different atolls in the Maldives. A. clarkii was associated with five species of host anemones, but A. nigripes was only found in Heteractis magnifica. In few cases, both anemonefishes have utilized the same individual of H. magnifica. There was no significant correlation between the size of the anemones and the number of the...

The reproduction of two species of Cichla (Cichla cf. ocellaris and C. monoculus, commonly known in Brazil as tucunaré) introduced in the Volta Grande Reservoir, southeastern Brazil, was analyzed. The period for spawning began at the end of the dry season (September) and extended until the end of the rainy season (January). The length of the first gonad maturation (L50) and the length at which ...

We set out to determine whether probiotic addition would improve larval development in the false percula clownfish Amphiprion ocellaris and to determine what molecular responses could be observed in the larvae following probiotic exposure. We supplied the probiotic bacterial strain Lactobacillus rhamnosus IMC 501 to clownfish larvae from the first day posthatch simultaneously by live prey and w...

Development of broodstock, spawning, and early rearing the hybrid clownfish, Amphiprion ephippium (♂) × melanopus (♀), was studied under captive conditions. The fishes were successfully paired after being together for over a year. Spawning occurred between 0700 to 1000 hours every 3 weeks. More than 200 eggs spawned each time, with an egg size 1.5 ± 0.5mm. Fertilized turned from bright orange b...
