“…Gamete stages were classified by using the characteristics described by Lavenda (1949), Nakamura et al (1998), and Benton and Berlinsky (2006). Gonadal photomicrographs of both male, female, and transitioning Black Sea Bass have been published (Howell et al 2003;Benton and Berlinsky 2006;Colburn et al 2009). Fish with any proportion of both testicular and ovarian tissue in the gonad were classified as transitional.…”

Influence of Size, Age, and Spawning Season on Sex Change in Black Sea Bass

A tagging study was conducted off the New Jersey coast to study sex change in Black Sea Bass Centropristis striata as a function of size, age, and spawning season. Throughout 2011–2013, 3,670 fish were measured and 1,498 were tagged from research, charter, and commercial fishing vessels. Of the tagged fish, 437 were recaptured. Size at 50% probability of sex change was 355 mm TL; the proportion of female fish in sexual transition increased with body size from 0.5% at 175–225 mm to 15.7% at 375–425 mm and increased with age from 0.6% at 3 years old to 18.2% at 6 years old. Relatively few females (8 of 107) changed sex during the spawning season, but a larger proportion (8 of 22 females) transitioned between spawning seasons. The proportion of females with transitional gonads was lowest at the start of the spawning season in June (0.2%), slowly increased over the summer, and sharply peaked just after the spawning season in October (9.5%). In addition, a high proportion of young mature fish were male (40% at age 2), which may indicate the presence of primary males. This is the first tagging study to estimate sex change as a function of size, age, and season in a protogynous hermaphroditic fish species. Use of tagging avoids potential problems that are associated with inferring sex change rates from sex ratios based on catch data.

“…These fish are in high demand but only seasonally available, which has contributed to broad research toward aquaculture development (Berlinsky et al, 2000;Atwood et al, 2003;Watanabe et al, 2003;Berlinsky et al, 2004;King et al, 2005;Alam et al, 2008b). Black sea bass change sex between 2-5 years of age, though this process is often accelerated in culture, and juveniles can undergo precocious sex change (Shepherd and Idoine 1993;Howell et al, 2003;Colburn et al, 2009). While social cues are known to influence sex ratios, black sea bass social dynamics are poorly understood and sex change progression is not associated with predictable coloration changes (Benton and Berlinsky, 2006;Provost et al, 2017).…”

Many teleost fishes exhibit sequential hermaphroditism, where male or female gonads develop first and later undergo sex change. Model sex change species are characterized by social hierarchies and coloration changes, which enable experimental manipulations to better understand these processes. However, other species such as the protogynous black sea bass (Centropristis striata) do not exhibit these characteristics and instead receive research attention due to their importance in fisheries or aquaculture. Black sea bass social structure is unknown, which makes sex change sampling difficult, and few molecular resources are available. The purpose of the present study was to induce sex change using exemestane, an aromatase inhibitor, and assess gonadal gene expression using sex markers (amh, zpc2) and genes involved in steroidogenesis (cyp19a1a, cyp11b), estrogen signaling (esr1, esr2b), and apoptosis or atresia (aen, casp9, fabp11, parg, pdcd4, rif1). Overall, dietary exemestane treatment was effective, and most exposed females *

“…The human aromatase gene is a single gene for which tissue-specific expression is controlled by alternate promoter splicing (Meinhardt and Mullis, 2002). Interestingly, teleost fish express two subtypes of aromatases cDNA, a predominantly ovarian form (cyp19a1a) and a predominantly brain form (cyp19a1b) (Piferrer et al, 1994;Simpson et al, 2002;Colbum, Walker & Berlinsky 2009). The cDNA encoding P450arom has been isolated from a number of vertebrates, including human (Corbin, Graham-Lorence, McPhaul, Mason, Mendelson & Simpson 1988;Harada 1988) and birds (McPhaul, Noble, Simpson, Mendelson & Wilson 1988).…”

Cytochrome P450 aromatase (P450arom) is an enzyme responsible for the conversion of androgen into oestrogen. To study the role of ovarian aromatase (Cyp19a1a) in sex differentiation, the novel cDNA clone encoding ovarian aromatase (Cyp19a1a) was identified from the ovary of the black rockfish (Sebastes schlegeli). The cloned cDNA is 1868 bp in length with 79 bp 5′U TR, 209 bp 3′UTR [excluding poly (A)] and contains 1550 bp ORF, encoding a protein of 516 amino acids. Alignment and phylogenetic analysis showed that the black rockfish ovarian aromatase (Cyp19a1a) shared 61–89% sequence identity with those of other seven fish species. The cyp19a1a transcript was found more highly abundant in ovary, but not detected in the testis, brain, liver, spleen, kidney, muscle, skin, heart, head kidney, gill, intestine and eyes by semi‐quantitative reverse transcription (RT)‐PCR. The cyp19a1a gene is not equivalent in tissue‐specific expression in the female and male, showed the possibility of distinct promoters and regulatory mechanisms. The expression level of cyp19a1a in ovary declined with the ovary development, but was higher than that in testis in all phases. These results indicated that cyp19a1a might be involved in gonadal development in S. schlegeli.
