Reef fishes of the families Pomacanthidae (angelfish) and Chaetodontidae (butterflyfish) are popular ornamental species, intensively harvested for the aquarium trade. The impacts of such activity on intra-specific diversity and reef ecosystems are still poorly understood in the south Atlantic. In the present work, a fine-scale genetic analysis using RAPD markers was performed in distinct samples of the queen angelfish (Holacanthus ciliaris), French angelfish (Pomacanthus paru), and banded butterflyfish (Chaetodon striatus) along the Brazilian coast. Most of the genetic variation in the three species was related to intra-population diversity. However, AMOVA results demonstrated that H. ciliaris presents a subtle population structure (φ st = 0.132, P = 0.003), while P. paru and C. striatus present low genetic differentiation, especially remarkable in the latter (φ st = 0.090, P = 0.001 and φ st = 0.041, P = 0.028, respectively). Gene flow (Nm) was also higher in C. striatus than in the angelfish species. The reported patterns of genetic differentiation contrast with the similar pelagic stage of the selected species, suggesting that larval dispersal per se is a poor predictor of population structure in these reef fishes. Ecological features coupled with biogeographic history and distinct local selective pressures might play a major role on the genetic composition of each species. Although preliminary, the present results provide a baseline for monitoring the genetic variability in these reef species. These differences in the genetic structure among co-occurring species should be taken into consideration for the conservation of eventual evolutionary units along the Brazilian Province.Keywords: angelfish, butterflyfish, dispersal, RAPD, reef fish. Diversidade genética em três espécies de peixes ornamentais de recifes (famílias Pomacanthidae e Chaetodontidae) da costa brasileira ResumoOs peixes recifais das famílias Pomacanthidae (peixes-anjo) e Chaetodontidae (peixes-borboleta) são espécies ornamentais populares, intensivamente coletadas para o comércio aquariófilo. Os impactos dessa atividade na diversidade intra-específica e no ecossistema recifal ainda são pouco conhecidos no Atlântico Sul. No presente trabalho, uma análise genética em fina escala usando marcadores RAPD foi realizada em diferentes amostras de Holacanthus ciliaris (anjo ciliaris), Pomacanthus paru (peixe frade) e Chaetodon striatus (borboleta striatus) ao longo da costa brasileira. A maior parte da variação genética nas três espécies relacionou-se à diversidade intrapopulacional. Contudo, resultados da AMOVA demonstraram que H. ciliaris apresenta uma estruturação populacional sutil (φ st = 0,132, P = 0,003), enquanto P. paru e C. striatus apresentam uma baixa diferenciação genética, particularmente reduzida na última (φ st = 0,090, P = 0,001 e φ st = 0,041, P = 0,028, respectivamente). O fluxo gênico (Nm) também foi mais alto em C. striatus do que nas espécies de Pomacanthidae. Os padrões de diferenciação genética registrados contrastam com...

“…Overfishing has caused a decline in king angelfish populations (Sánchez-Alcántara et al, 2006), thus, in the Gulf of California, the species was included in the list of protected species by the Mexican norm NOM-059- SEMARNAT-2001(Mexico, 2002 as the first conservation effort of the government. Additionally, it is well known that the reproduction of marine finfish under controlled conditions also reduces the impact of heavy fishing pressure on wild populations (Mehdi and Ehsan, 2011;Arantes et al, 2012), but successful reproduction in captivity requires the knowledge of several aspects of the adult life stage of an organism (Izquierdo et al, 2001;Olivotto et al, 2011).…”

Fatty acid and proximate composition of wild male and female king angelfish (Holacanthus passer) gonads during the ripe and spent developmental stages

et al. 2016

Overfishing of king angelfish Holacanthus passer reduced populations in the Gulf of California. This study aimed to determine the fatty acid and proximate composition of male and female gonads, and the E2 concentration in plasma of wild organisms with different stages of gonadal development captured during early and mid-summer at El Datil, near Kino Bay, Sonora, Mexico, to help establish basic reproductive aspects and possibly to help develop the aquaculture of this ornamental species. Out of the 45 adult specimens analyzed, 66.7% were females and 33.3% were males; 16.7% of the females had ripe gonads while 83.3% had spent gonads, and 20% of males had ripe gonads while 80% had spent gonads, indicating they were reproducing earlier, likely in the spring. Females had smaller size but numerically greater gonadosomatic index (GSI) and condition factor (K) than males. Ripe and spent females showed no statistical differences in weight, length or K; however, ripe females showed significantly higher GSI (P = 0.0005) than spent females, 3.43 vs. 0.87%. Lipid content was higher in ripe gonads, with higher content of fatty acids. In both sexes, DHA was quantitatively the major fatty acid, (10.83-16.28 mg of DHA g -1 of gonad wet weight). The n-3/n-6 ratios varied from 1.99 to 3.54, lower for ripe organisms due to a higher content of ARA and n-6 derivatives. Gonad DHA content changed in relation to its developmental stage and it might serve as an additional maturation index. Information on the chemical composition and fatty acid profile of the gonads can be used as indicators of dietary lipid and essential fatty acid requirements of broodfish, which may contribute to the formulation of a balanced diet for the culture of this ornamental species.

“…The King angelfish, Holacanthus passer, is one of the most iconic fish species of the Tropical Eastern Pacific (TEP) (Figure 1). Its distribution ranges from the Northern Gulf of California (Sea of Cortez) to Peru, including the Revillagigedos, Cocos, Malpelo, and the Galápagos Islands [1,2] (Figure 1C). Due to their conspicuous coloration, the King angelfish have become a target for the aquarium trade [2], with individuals costing between $150 and $900 (at the time of publication), while individuals of the sister species, H. clarionensis, endemic to the Revillagigedos, have sold for up to $15,000.…”

Holacanthusangelfishes are some of the most iconic marine fishes of the Tropical Eastern Pacific (TEP). However, very limited genomic resources currently exist for the genus. In this study we: i) assembled and annotated the nuclear genome of the King Angelfish (Holacanthus passer),and ii) examined the demographic history ofH. passerin the TEP. We generated 43.8 Gb of ONT and 97.3 Gb Illumina reads representing 75X and 167X coverage, respectively. The final genome assembly size was 583 Mb with a contig N50 of 5.7 Mb, which captured 97.5% complete Actinoterygii Benchmarking Universal Single-Copy Orthologs (BUSCOs). Repetitive elements account for 5.09% of the genome, and 33,889 protein-coding genes were predicted, of which 22,984 have been functionally annotated. Our demographic model suggests that population expansions ofH. passeroccurred prior to the last glacial maximum (LGM) and were more likely shaped by events associated with the closure of the Isthmus of Panama. This result is surprising, given that most rapid population expansions in both freshwater and marine organisms have been reported to occur globally after the LGM. Overall, this annotated genome assembly will serve as a resource to improve our understanding of the evolution ofHolacanthusangelfishes while facilitating novel research into local adaptation, speciation, and introgression in marine fishes.
