“…This mortality is possibly associated with morphological and physiological limitations of the angelfishes larvae, such as reduced body and mouth size, and specific nutritional requirements (Baensch, 2017), making the first exogenous feeding difficult. Furthermore, abiotic factors, such as temperature (Mendonça, Ikebata, et al, 2019; Mendonça, Mattos, et al, 2019), photoperiod (Holt & Riley, 2001) and salinity (Olivotto et al, 2017), influence the development of the dwarf angelfishes embryo and yolk sac larvae.…”

The dwarf angelfish Centropyge aurantonotus, commonly known as the flameback angelfish, Pomacanthidae family, is the only species of the genus that occurs in Brazil (Lindner, 2014). Dwarf angelfishes are attractive to the aquarium market due to their beautiful colours and small body size (Baensch, 2017). C. aurantonotus is among the most commercialized angelfish species in Brazil (Ibama, 2008), and its exports exceeded 20,000 specimens from 2006 to 2015 (Gurjão & Lotufo, 2018).In the IUCN Red List of Threatened Species (Pyle et al., 2010), the flameback angelfish is listed as 'Least Concern'. However, this fish has

“…However, there is limited information on the basic reproductive biology of the majority of commercially relevant ornamental fish species (Moorhead & Zeng, ; Shei, Mies, & Olivotto, ; Wittenrich, ). Marine teleosts, especially those associated with coral reefs, display the greatest diversity of reproductive strategies and sexual patterns (Godwin, ; Olivotto et al, ; Sadovy de Mitcheson & Liu, ). Gonochorism, defined as the expression of a single reproductive function during an individual life cycle (see Sadovy de Mitcheson & Liu, ), is common among marine teleosts (Shapiro, ).…”

“…Marine ornamental fish aquaculture (MOFA) is a growing activity that both preserves coral reef resources and supplies the hobby demand (Olivotto et al, 2011;Pomeroy, Parks, & Balboa, 2006;Tlusty, 2002). MOFA is still in an early stage of development, and baseline research efforts are ongoing mainly within the topics of reproductive performance, broodstock nutrition, and optimization of larval rearing protocols (Craig, Gardner, & Carnevali, 2017;Moorhead & Zeng, 2010;Olivotto, Leu, & Blázquez, 2017;Wittenrich, 2007). However, there is limited information on the basic reproductive biology of the majority of commercially relevant ornamental fish species (Moorhead & Zeng, 2010;Shei, Mies, & Olivotto, 2017;Wittenrich, 2007).…”

The marine aquarium industry has grown significantly and so has marine ornamental fish aquaculture. The main species targeted by commercial aquaculture are clownfish, dottybacks, gobies, and blennies. However, the limited knowledge available for the reproductive biology of several fish species hinders production, especially for blennies. Therefore, this study investigated whether two massproduced blenniids, Meiacanthus nigrolineatus and Meiacanthus smithi, are gonochorists and display caudal fin sexual dimorphism. For this purpose, gonadal samples and morphometric data were collected from specimens of both species kept in captivity for 6 months. Histological preparations of the whole individuals or their gonads were performed and analyzed. Results show that sex ratio does not differ from 1:1 and that gonadal development was similar to other blenniids. No evidence of sexual reversion or simultaneous hermaphroditism was found in the first 8 months of development, suggesting that both species are gonochoric. Differences in the length of upper and lower rays in the caudal fin were not detected for M. smithi, but M. nigrolineatus male individuals displayed significantly longer upper and lower rays, confirming it as a dimorphic trait for this species. The identification of the sexual pattern and sexually dimorphic traits may aid in broodstock pairing for M. nigrolineatus blennies, improving its aquaculture

“…Knowledge of the life history of marine ornamental fishes is crucial to the success of their captive propagation (Holt, ; Leu, Sun, & Meng, ; Olivotto, Leu, & Blázquez, ). Fishes of the family Gobiidae have great potential for the aquarium trade because of their diverse colours, peaceful behaviours and ease of domestication and adaptation to commercial feed and home aquaria (Darcy, ; Olivotto et al, ; Shei, Mies, & Olivotto, ).…”

Natural spawning, early development and larviculture of the ornate goby Istigobius ornatus in captivity were studied for the first time. I. ornatus spawned 46 times from 31 October 2013 to 31 October 2014. Fecundity ranged from 246 to 10,214 eggs per clutch, with an average hatching rate of 77.8% ± 9.9% (M ± SEM). Fertilized eggs (1.31-1.54 × 0.46-0.50 mm in diameter) were adhesive demersal and oval-shaped.Embryonic development lasted 84 hr at 27.5 ± 0.5°C. Newly hatched larvae [2.12 ± 0.04 mm in total length (TL)] transformed to the juvenile stage completely when TL was 7.79 mm. Effects of different water temperatures (24, 28 and 32°C) and salinities (10, 15, 20, 25, 30, 35 and 40 g/L) on per cent survivals (%) and survival activity indices (SAIs) were tested. Survival was not significantly different under different temperatures; SAIs was significantly higher at 28°C. Larvae showed the significantly higher survival and SAIs at salinities 10-30 g/L than at 35 and 40 g/L.Effect of different prey densities on survival was significantly higher in 7 days post hatch larvae fed 20 and 30 rotifers/ml. These findings could guide future programs in captive breeding technology development and commercial production of other marine ornamental gobies.
