“…The maximum age of 14 yr exceeds those values reported for Brazilian waters in the past (12 yr, MENEZES, 1985) and for Caribbean waters (7 yr, MANOOCH; DRENNON, 1987). The presence of individuals considerably older than the mean age sampled in our study suggests the fishery effort had not been capable of inducing changes in the age structure of the B. vetula population before1999.…”

“…This attribute had been reported earlier when MANOOCH; DRENNON (1987) observed spines with large cross-sectional diameter and distinct growth rings. Surprisingly, core reabsorption or lumen expansion, features frequently found in fish spines (PRINCE et al, 1986;TSERPES;TSIMENIDES, 1995;HOOLIHAN, 2006), were almost never observed, which has increased our confidence regarding the age estimation performed here.…”

“…Off the central coast of Brazil, where our samples were collected, there are annual temperature variations of about 4 o C (NIMER, 1989), which match the 4 to 5 o C suggested as necessary to induce the production of seasonal growth increments in fish hard structures (LONGHURST;PAULY, 1987). Spines of B. vetula from the Virgin Islands have been found to form one growth band per year, mostly in winter and spring (MANOOCH; DRENNON, 1987), however the authors have not inferred which factor would be the cause of the reported annual periodicity. Studies in spines of the congenerous species B. capriscus in Southeastern Brazil have revealed the formation of two growth bands per year, which would be promoted by low food availability/low temperatures in winter, and reproduction in summer (BERNARDES, 2002).…”

“…Growth and population information on B. vetula is quite scant. A few growth studies based on its structural hard parts were undertaken more than 20 years ago for the American Virgin Islands (MANOOCH; DRENNON, 1987) and for Brazilian central waters (MENEZES, 1985) and have indicated that this species presents longevity of more than 10 years.…”

“…It is a reef fish species widely distributed throughout the Atlantic Ocean, occurring on the western margin from Canada to Uruguay, and on the eastern margin from Spain to southern Angola. Queen triggerfish are mostly found over rocky surfaces below 100 m deep and in shallow waters close to sandy beaches and phanerogamae prairies (MANOOCH;DRENNON, 1987). They are known to feed on a broad range of benthic prey, particularly on gastropods, echinoderms, small fish and other invertebrates (COSTA et al, 1987), using their robust jaws and strong teeth to break the hard parts of their prey (TURINGAN; WAINWRIGHT, 2005).…”

A B S T R A C TDorsal spines (n=649) of the queen triggerfish Balistes vetula were collected between 1997 to 1999 at the central coast of Brazil and used to evaluate fish growth. The marginal increment analysis validated that 1 increment was formed annually (n=476), with minimum values observed at the summer, and coinciding with the maximum proportion of translucent growth bands. Fish's maximum fork length and age were 460 mm and 14 years respectively. The parameters of the von Bertalanffy function were: Fl∞ = 441.3 mm, K = 0.14 and T0= -1.8. Weight gain by year ranged from about 110 g yr -1 for age 5 to about 30 g yr -1 for age 14. Compared to other studies, B. vetula growth in the Central coast of Brazil was slow, which could be related to the influence of the oligotrophic water from Brazil current. Our results indicate that B. vetula's fisheries in the Central coast of Brazil until 1999 have caught mostly adult individuals over the sexual maturation lenght, 60% of them with ages from 6 to 8 yr. R E S U M OEntre 1997 e 1999 foram amostrados 649 espinhos de Balistes vetula na costa central do Brazil e foram utilizados para a avaliação de crescimento. A validação de anéis anuais de crescimento foi realizada através da analise de incrementos marginais, cujos valores mínimos foram observados durante o verão, coincidindo com a maior proporção de anéis translúcidos na borda do espinho. Portanto, forma-se um anel de crescimento a cada ano. A idade e o comprimento padrão máximos observados foram respectivamente 14 anos e 460 mm. Os parâmetros da equação de von-Bertalanffy foram: Fl∞ = 441,3 mm, K = 0,14 e T0= -1,8. O incremento anual em peso variou de 110 g yr -1 para a idade 5 a 30 g yr -1 para a idade 14. Comparados a outros estudos, nossos resultados indicam taxas de crescimento mais baixas, que podem ter sido induzidas pela influência oligotrófica da corrente do Brasil ao longo da costa central do Brasil. Nossos resultados indicam que a pesca do peroá até 1999 estava principalmente voltada a indivíduos adultos, com tamanhos acima do comprimento de primeira maturação sexual e cerca de 60% dos indivíduos capturados apresentando idades entre 6 e 8 anos.

Ciguatoxin prevalence in 4 commercial fish species along an oceanic exposure gradient in the US Virgin Islands

Ciguatera fish poisoning is a seafood-toxin illness resulting from consumption of fish contaminated with ciguatoxins. Managing ciguatera fish poisoning is complex. It is made easier, however, by local fishers from endemic areas reporting regional predictability for local fish species' ciguatera fish poisoning risk, which the present study then tested. We investigated the prevalence of ciguatoxins in 4 commonly marketed and consumed species (Balistes vetula, Haemulon plumierii, Ocyurus chrysurus, and Epinephelus guttatus) across an oceanic gradient (north, south, east, and west) from the US Virgin Islands. Fish muscle extracts were analyzed for Caribbean ciguatoxins using an in vitro mouse neuroblastoma (N2a) cytotoxicity assay and confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Fish collected from the north location had 0 fish with detectable ciguatoxins; this site also had the greatest wave energy. Caribbean ciguatoxins in fish ranged from 0.01 to 0.11, 0.004 to 0.10, and 0.005 to 0.18 ng Caribbean ciguatoxin-1 eq/g, from the west, east, and south respectively. Ciguatoxin-like activity was detectable by the N2a assay in 40, 41, 50, and 70% of H. plumierii, O. chrysurus, B. vetula, and E. guttatus, respectively. Of the fish collected, 4% had Caribbean ciguatoxin levels exceeding the US Food and Drug Administration guidance of 0.1 ng Caribbean ciguatoxin-1 eq/g fish. These findings concurred with spatial ciguatera fish poisoning prevalence information provided by local fishers in the US Virgin Islands and demonstrate how partnerships between researchers and fishers can aid the improvement of science-based ciguatera fish poisoning management.

Data‐limited approaches to managing fisheries are widespread in regions where insufficient data prevent traditional stock assessments from determining stock status with sufficient certainty to be useful for management. Where severe data limitations persist, a catch‐only approach is commonly employed, such as in the U.S. Caribbean region. This approach, however, has not received the level of scrutiny required to determine the potential long‐term risks (e.g., probability of overfishing) to fish stocks. In this study, we present a framework for comparison and implementation of data‐limited methods, including the static Status Quo approach, which uses average catch landings. Candidate species for stock evaluation were identified through a data triage and included Yellowtail Snapper Ocyurus chrysurus (Puerto Rico), Queen Triggerfish Balistes vetula (St. Thomas and St. John), and Stoplight Parrotfish Sparisoma viride (St. Croix). Feasible data‐limited methods, based on data availability and quality, included empirical indicator approaches using relative abundance (i.e., catch per unit effort) or mean length. Results from the management strategy evaluation support the use of adaptive data‐limited methods, which incorporate feedback in contrast to the static Status Quo approach. The proposed framework can help guide the development of catch advice for dynamic fisheries management in data‐limited regions.
