The Haemulon plumieri is a typical reef-associated and tropical species found in warm and temperate waters of the Western Atlantic. Due to the large fishing effort directed to H. plumieri, the knowledge about its reproductive biology is essential for correct stock management and conservation. The aim of this study was to characterise reproductive biology with a focus on its seasonal variation of gonadal maturation stages, first maturation size and fecundity. Specimens were monthly collected and a total of 119 females and 136 males were analysed. The reproductive cycle of Haemulon plumieri is seasonal, with higher activity between March and May. Size at first maturity (L 50 ) was estimated at 16.86 and 18.55 cm for females and males, respectively. The total fecundity ranged between 17,816 and 120,333 mature oocytes per female and relative fecundity was 235 ± 63 oocyte.g -1 whereas batch fecundity varied between 20 and 25% from total fecundity. Since the species is widely caught, we suggest a closed season from March to May and to establish a minimum catch size of 18.5 cm for both sexes, since there is no evident sexual dimorphism.Keywords: reproduction, fecundity, reef fish. Biologia reprodutiva de Haemulon plumieri (Teleostei: Haemulidae) no Nordeste do Brasil ResumoO Haemulon plumieri é uma espécie tropical, associada aos recifes, encontrada em águas quentes e temperadas do Atlântico Oeste. Em razão do grande esforço de pesca direcionado para a captura desta espécie, o conhecimento acerca da biologia reprodutiva é essencial para um correto manejo e a sua preservação. O objetivo do presente estudo foi caracterizar a biologia reprodutiva com um foco na variação sazonal dos estágios de maturação, no tamanho de primeira maturação e na fecundidade. Espécimens foram mensalmente coletados e um total de 119 fêmeas e 136 machos foi analisado. O ciclo reprodutivo de Haemulon plumieri é sazonal, com maior atividade entre os meses de março e maio. O tamanho de primeira maturação (L 50 ) foi estimado em 16,86 cm para as fêmeas e 18,55 cm para os machos. A fecundidade total variou de 17.816 a 120.333 oócitos maturos por fêmeas e a fecundidade relativa foi 235 ± 63 oócitos.g -1 , enquanto que a fecundidade parcial variou entre 20 e 25% da fecundidade total. Uma vez que a espécie é amplamente capturada, sugere-se que seja definido um período de defeso de março a maio e que se estabeleça um tamanho mínimo de captura de 18,5 cm, para ambos os sexos, já que não há dimorfismo sexual evidente.Palavras-chave: reprodução, fecundidade, peixe recifal.

“…Males were categorized based on the macroscopic aspects of their gonads, as well as on the histological configuration of testicular lobes and spermatogenic cell lineages. It was done by following the gonadal maturation scale developed for Hamulids, according to Shinozaki-Mendes et al (2013), and adapted to three maturation stages, namely: immature (n=7), maturing (n=7), mature (n=7) -21 specimens, in total.…”

Differential gene expression pattern and plasma sex steroids during testicular development in Genyatremus luteus (Perciforme: Haemulidae) (Bloch, 1790)

The aim of the current study is to evaluate gene expression patterns of LH (lhr) and estrogen (er) receptors and plasma steroid levels during testicular development in Genyatremus luteus. Males were histologically classified as immature (n=7), maturing (n=7) and mature (n=7), based on the cellular structure of their testes. Plasma 11-KT concentration recorded peak at the final maturation stage. The highest plasma 17α-OHP concentrations were observed at the immature stage; they decreased at the maturation and mature stages. On the other hand, 17β-estradiol (E2) recorded higher concentrations at the maturation stage. Er expression has significantly increased along the maturational development of animals’ testes. The mRNA observed for the LH receptor has decreased from immature to maturing stage; it presented expression peak at the mature stage. There was high association between receptor gene expression and plasma steroid levels, mainly E2. The current study was the first to feature different reproductive maturation stages in male G. luteus specimens, based on cellular, endocrine and molecular aspects. In addition, it has shown that the gene expression profile for er and lhr receptors, as well as plasma 11-KT and E2 concentrations, are directly linked to testicular maturation, although they are not necessarily associated with the gonadosomatic index.

Highlights► Haemulidae are broadly distributed through Northeast coast of Brazil due to the complex habitat presents in this region. ► H. plumierii, H. aurolineatum and H. squamipinna were considered the most dominant species among the Family. ► The population structure, and size at first maturity were characterized for the most dominant species of Haemulidae (3 spp.) in Northeastern Brazil. ► The southern coasts of Pernambuco and Rio Grande do Norte hold high abundance, richness and concentration of juveniles. 2009). Currently, haemulids and lutjanids are commonly caught by artisanal fisheries as the target species, owing to the decrease in abundance of lobster and goatfish (LESSA et al., 2009; MARQUES & FERREIRA, 2013).Despite their ecological and economic importance, many biological aspects of this family are still unknown or knowledge is restricted in terms of spatial coverage. Available studies do not integrate information about population structure, distribution, abundance, and the habitats occupied by these species. Previous studies in Northeast Brazil have mainly investigated specific aspects of population dynamics, such as the length-weight relationship (
