“…However, up to 27% of larval mortality was observed in the first weeks after hatching. This high larval mortality may be due to the stress and injury caused during larval transfer from the spawning tank to the larval rearing tank, and high mortality at this period was generally inevitable (Madhu, Madhu, & Retheesh, ). The findings of the present study supported this assertion.…”

In the present study, we report the first successful instance of controlled reproduction in Scatophagus argus, which has recently emerged as a new aquaculture resource. The controlled reproduction process for S. argus was optimized with regard to salinity acclimation. Gonadal maturation was affected by salinity in both sexes. Levels of plasma 17β‐estradiol (E2) and 11‐ketotestosterone (11‐kT) were salinity dependent and increased significantly with the duration of acclimation. Plasma levels of gonadal steroids were higher in fish held at 25‰ salinity. The highest gonadosomatic indices (GSI), 15.1 ± 1.6 in the female and 6.4 ± 1.2 in the male, were also observed at 25‰ salinity. Nevertheless, the optimal salinity for S. argus embryonic development and larval culture was 15‰. Thus, the salinity requirement for gonadal maturation and early development are quite different. The use of advanced reproductive technologies combining salinity acclimation and stimulation of luteinizing hormone‐releasing hormone analog (LHRH‐A2) resulted in a fertilization rate of 83.2%–91.3% and embryonic survival rates of over 90%. Embryos of S. argus at the 2‐cell, blastula, gastrula and pharyngula stages were observed. Most embryos hatched after 21.0 hr of incubation at 28.0 ± 1.0°C. The development of larvae into juveniles was completed at 40–45 days posthatch (dph). In this study, we provide information about the controlled reproduction of S. argus and identify the optimal environmental parameters for S. argus embryonic and larval culture, with the aim of developing reliable reproductive techniques for its mass production.

“… 11 , 14 , 32 , 36 These well‐defined stages provide a framework for testing hypotheses of homologies within the various processes that occur during the embryonic development of teleost fishes. We observed interesting morphological differences between the embryos of false clownfish and other teleost species, whether they are aquaculture species (the sea bass Dicentrarchus labrax , 34 the turbot Scophtalmus maximus , 37 the batfish Platax teira 38 ), other coral reef fish (the damselfish Neopomacentrus cyanomus , 19 the dottybacks Pseudochromis dilecticus , 17 the mandarinfish Synchiropus splendidus , 39 the goby Elacatinus puncticulatus , 40 several angelfishes of the genus Centropyge 18 , 41 ) or other fish models (the stickleback G aculeatus , the salmonid Coregonus clupeaformis , 12 the gadid Trisopterus luscus , 42 the wrasse Labrus bergylta 43 ). These include the shape of the yolk/chorion, different early chromatophore patterns, and variation in developmental timing.…”

Background: Amphiprion ocellaris is one of the rare reef fish species that can be reared in aquaria. It is increasingly used as a model species for Eco-Evo-Devo. Therefore, it is important to have an embryonic development table based on high quality images that will allow for standardized sampling by the scientific community. Results: Here we provide high-resolution time-lapse videos to accompany a detailed description of embryonic development in A ocellaris. We describe a series of developmental stages and we define six broad periods of embryogenesis: zygote, cleavage, blastula, gastrula, segmentation, and organogenesis that we further subdivide into 32 stages. These periods highlight the changing spectrum of major developmental processes that occur during embryonic development.Conclusions: We provide an easy system for the determination of embryonic stages, enabling the development of A ocellaris as a coral reef fish model species. This work will facilitate evolutionary development studies, in particular studies of the relationship between climate change and developmental trajectories in the context of coral reefs. Thanks to its lifestyle, complex behavior, and ecology, A ocellaris will undoubtedly become a very attractive model in a wide range of biological fields.

“…cyanide fishing) in tropical developing countries are particularly controversial, as such practice threatens non-target organisms including corals (Barber and Pratt, 1998;Olivotto et al, 2003). Aquaculture of marine ornamental fish is therefore perceived as a sustainable alternative to reduce the fishing pressure on the wild stocks and help protect fragile coral reefs ecosystem (Madhu et al, 2016;Palmtag, 2017). Unfortunately, to date, there are only less than 30 species of marine ornamental fish that can be produced in commercial scale due to a major bottleneck: larviculture (Holt, 2003;Callan et al, 2018).…”

SummaryMarine angelfish (family: Pomacanthidae) are among the most sought-after fish species in the saltwater aquarium trade. However, there is a lack of information in the literature on their early ontogeny. The objective of this study was to describe the embryonic and early larval development of two dwarf angelfish, the bicolour angelfish, Centropyge bicolor and the coral beauty angelfish, Centropyge bispinosa. The eggs of these two species were obtained from spontaneous spawning of the broodstock fish in captivity and incubated at 26.0 ± 0.2°C throughout the study. Fertilized eggs (n = 15) of both species are transparent, pelagic and spherical; the mean diameters of the eggs were measured at 703.6 ± 7.8 μm for C. bicolor and 627.6 ± 7.8 μm for C. bispinosa. The eggs of both species possessed a narrow perivitelline space, smooth and thin chorion, a homogenous and non-segmented yolk as well as a single oil globule. Overall, the observed embryonic development pattern of C. bicolor and C. bispinosa was very similar, and the main difference was the embryonic pigmentation pattern, which only became evident close to hatching. Larvae of both species started hatching at 13 h 30 min after fertilization, and the larval characteristics of both species also showed high levels of similarities. However, the mouth opening time for C. bicolor was 72 h after hatching (AH) and 96 AH for C. bispinosa. In general, the observed early ontogeny of C. bicolor and C. bispinosa also resembled that of other Centropyge species documented in the literature.
