“…The ovotestis structure of S. atricauda follows the type of organization that is typical of Serranidae family and which is also found in other species of Serranus inhabiting the Eastern Atlantic and Mediterranean: S. cabrilla (García-Díaz et al 1997); S. scriba (Tuset et al 2005;Alonso-Fernández et al 2011) and S. hepatus (Bruslé 1983). The similarities found in these four species were highlighted by Erisman and Hastings (2011) where these species form a group within the Serranus clade in the phylogenetic hypothesis tree obtained in their reproductive evolution study.…”

“…This was probably due to the fact that the target species in the Portuguese fishery is not the blacktail comber, but the Atlantic wreckfish (Polyprion americanus) and large hooks are used in the longline fishery. Therefore, small individuals which live in shallower waters (Tuset et al 2004) and feed mainly on benthic species (Morato et al 2000) are not caught. The absence of these small individuals made it impossible to estimate other reproductive parameters like the maturity ogive and length at 50 % maturity.…”

Reproductive patterns of blacktail comber (Serranus atricauda, Serranidae) from south-west Portugal seamounts

The knowledge of the reproductive strategy is essential for the comprehensive understanding of the population dynamics of any fish species. This study intends to define the spawning season, verify the type of fecundity regulation and estimate relative annual fecundity for Serranus atricauda inhabiting the south-west of Portugal seamounts (Gorringe, Ampère and Lion). Monthly samples, between September 2010 and December 2011, were obtained from commercial vessels. This species is synchronously hermaphroditic, and mature individuals were found all year round, with gonadosomatic index peak from February to September. No clear relation between hepatosomatic index and Fulton's condition factor and gonadal development was found, and therefore, it is probable that reproductive success depends more on environmental conditions and food availability during the spawning season than on body energy reserves. No gap exists between pre-vitellogenic and vitellogenic oocytes and the oocyte size-frequency distribution during the main spawning season show no dominant cohort progressing through time. The number of standing stock of advanced vitellogenic oocytes showed an increase trend along the spawning season decreasing only at its end and the relative intensity of a-atresia was always low throughout this period with an increase towards the end. All these criteria corroborate the indeterminate fecundity type assigned to S. atricauda in previous studies. Mean relative annual fecundity estimated was 5,655 ± 4,321 oocytes per gram of gutted weight.

“…It is considered a by-catch or low-value species by the commercial fishery, but it is highly targeted and appreciated by the recreational fishery (Morales-Nin et al 2005. S. scriba is a simultaneous hermaphrodite, with asynchronous oocyte development and a batch spawning pattern (Tuset et al 2005, Zorica et al 2005, AlonsoFernández et al 2011. Sexual maturity is achieved during the first or second year (Alos et al 2010), and the spawning season extends from May to August, with a peak of spawning activity between May and June in the western Mediterranean (Alonso-Fernández et al 2011).…”

SUMMARY:We studied multiple individual parameters that affect the reproductive output in the painted comber Serranus scriba, a simultaneous hermaphroditic fish that is widely exploited by recreational fishing in temperate marine coastal regions. Batch fecundity was significantly affected by maternal size, but was not related to maternal age or condition. However, egg quality as estimated by egg dry weight was significantly influenced by the interaction effect of maternal size and age. An empirical assessment demonstrated the existence of a diel spawning pattern based on a daily release of a partial fraction of eggs related to sunset time. Buoyancy varied during the incubation period, but it consistently resulted in positive buoyancy that situated the eggs near the top of the water column. This study represents the first estimation of reproductive output of the simultaneous hermaphrodites S. scriba and also provides a comprehensive study about the potential maternal factors that affect egg production. These results are a crucial step towards ongoing efforts to improve the stock assessment of this species.Keywords: batch fecundity, egg buoyancy, egg quality, maternal effects, Mediterranean, Serranus scriba. RESUMEN: CaraCterístiCas del rendimiento reproduCtivo del hermafrodita simultáneo SerranuS Scriba en el mediterráneo oCCidental (islas Baleares). -Se estudiaron varios parámetros individuales que afectan el éxito reproductivo de la especie Serranus scriba, un pez hermafrodita simultáneo que es intensamente explotado por la pesca recreativa en regiones costeras de aguas templadas. La fecundidad parcial está significativamente relacionada con el tamaño de los individuos; pero no se encontró relación con la edad o condición. Sin embargo, la calidad de los huevos (estimada a partir del peso seco) resultó significativamente influenciada por la interacción del tamaño y edad de los individuos. Se demostró empíricamente la existencia de un patrón de desove diario, basado en la puesta diaria de una fracción de los huevos del total con anterioridad a la puesta del sol. La flotabilidad de los huevos varió durante el período de incubación; pero presentando de forma consistente una flotabilidad positiva que sitúa a los huevos liberados cerca de la parte más superficial de la columna de agua. Este estudio representa la primera estimación de los parámetros reproductivos relacionados con la producción de huevos en el hermafrodita simultáneo Serranus scriba. Proporciona además un detallado estudio sobre los posibles factores parentales que afectan a la producción de huevos en esta especie. Estos resultados son un paso fundamental para los esfuerzos en curso para mejorar la evaluación y gestión de las poblaciones de Serranus scriba.Palabras clave: fecundidad parcial, flotabilidad de los huevos, calidad del huevo, efectos parentales, Mediterráneo, Serranus scriba.

“…In many cases, this is a response to different growth rates, where the larger otoliths (morphotype I) grow faster than smaller ones (morphotype II). Furthermore, one can deduce that slow-growing individuals have larger and heavier otoliths than fast-growing ones of the same length (Secor & Dean, 1989;Reznick et al, 1989;Worthington et al, 1995;Tuset et al, 2004), since faster growth produced long thin crystals compared with shorter more compacted ones in slower-growing fish (Gauldie & Nelson, 1990). The differentiation of two otolith morphs between wildfarmed and wild fish in salema is clear evidence of the intake of aquafeeds.…”

Phenotypic plasticity in wild marine fishes associated with fish-cage aquaculture

Two opportunistic fish species associated with fish farms, bogue (Boops boops) and salema (Sarpa salpa), were studied to infer whether changes in their feeding habits may cause a phenotypic response in body and otolith shape. Specimens were collected close to aquaculture cage sites, called 'wildfarmed fish', and from control sites far away from these areas, called 'wild fish'. The fish body shapes were examined with geometric morphometric analysis using 21 landmarks. The otolith contours were analysed using wavelet function, whereas otolith weights were used as indicators of fish growth rates. Statistically significant differences were observed in body shape between wild-farmed fish and wild fish of both species. The wild-farmed fish had a smaller head and eye, and in bogue also a slighter snout curvature and head depth. Otolith shape and weight did not differ between groups in bogue. By contrast, there were significant differences in otolith shape and weight between groups in salema. A complementary study in salema indicated that the wild-farmed fishes grew more in weight and accumulated higher concentrations of 'terrestrial fatty acids' (linoleic and alphalinolenic acids), which are used in fish feeds. Our findings clearly demonstrated an influence of coastal sea cages on metabolism of some wild fishes.
