“…All fish used in the study were marked with passive integrated transponder (PIT) tags (Trovan Ltd., UK), which were read using a tag reader Power Tracker V (Avid, UK). Two similar GnRHa spawning induction experiments (experiments 1 and 2) were made in consecutive years (2009 and 2010) during the natural spawning period of the meagre (Duncan et al, 2012(Duncan et al, , 2013Mylonas et al, 2013a,b). In both experiments broodstock were held in natural environmental conditions in tanks that were supplied with a flow through (400% daily water exchange) of full strength sea water (35 ppt).…”

“…The meagre (Argyrosomus regius) is a species that has been identified for the diversification of Mediterranean aquaculture (EATIP Vision, 2012), due to its rapid growth rate and good flesh quality (Monfort, 2010;Duncan et al, 2013). Unfortunately, in common with many other fish species meagre exhibit reproductive dysfunctions when held in captivity (Duncan et al, 2012;Mylonas et al, 2013a,b).…”

“…The meagre Argyrosomus regius (Sciaenidae) is a species with great potential for the diversification of aquaculture production in the Mediterranean region (Duncan et al, 2013;Monfort, 2010). Its aquaculture production has increased rapidly in the last decade, though reproduction in captivity still remains a problem (Duncan et al, 2013).…”

“…Its aquaculture production has increased rapidly in the last decade, though reproduction in captivity still remains a problem (Duncan et al, 2013). With few exceptions, females do not mature in captivity (Duncan et al, 2013;Gil et al, 2013;Mylonas et al, 2013b), and exogenous hormones need to be used to induce ovulation and spawning (Duncan et al, 2012).…”

Recently, meagre growth has been widely studied in different culture systems (Pastor et al 2002, El-Shebly et al 2007, Chatzifotis et al 2010, Vargas-Chacoff et al 2014) and with different diet compositions (Piccolo et al 2008, Estévez et al 2011, Chatzifotis et al 2012, Velazco-Vargas et al 2014 due to the increasing interest in meagre for diversification of aquaculture.…”

Abstract:The resilience of released hatchery-reared specimens increases with age and size, but production costs are also greater for these individuals. Therefore, for a given budget, the consequences of increasing age and size impose a trade-off between producing a large number of vulnerable (small) fish or a small number of resilient (large) fish. Once the optimal size for releasing fish has been defined, the choice of rearing protocol will determine the number and quality of the fish that can be released. In this study, different rearing protocols were compared using meagre juveniles (Argyrosomus regius), which are presently the target of a restocking programme conducted in the Balearic Islands (western Mediterranean). Seven different diets were compared during the grow-out phase to identify the diets that produced good-quality juveniles of a given size at the lowest cost. Most of the diets produced juveniles of suitable biological quality in terms of growth, fish condition (relationships between length and total weight, liver weight and mesenteric fat weight) and tissue biochemical composition. A semi-moist diet (Diet G) provided the best growth rate, closely followed by commercial meagre pellets (Diet A). In contrast, the cost of growing fish with Diet A was lower for any possible size at release. This study demonstrates the need to consider both growth rate and production cost to select the rearing protocol that maximizes the number of juveniles that can be produced for a given budget and desired release size. These considerations will ultimately increase the chance of success of restocking programmes.Keywords: Argyrosomus regius; restocking programme; production cost; fish quality; diet.La dieta usada en la cría puede determinar el éxito en la repoblación de peces: el caso de juveniles de corvina Argyrosomus regius criados en cautividad Resumen: La resiliencia de los ejemplares criados en cautividad y liberados se incrementa con la edad y el tamaño, pero los costes de producción también aumentan. Por lo tanto, para un presupuesto dado, estas consecuencias del incremento de la edad y el tamaño imponen un compromiso entre la producción de un gran número de peces vulnerables (pequeños) o un pequeño número de peces resistentes (grandes y de más edad). Una vez que el tamaño óptimo para la liberación de peces se ha definido, la elección del protocolo de cría determinará el número y la calidad de los peces que se pueden liberar con un presupuesto dado. En este estudio, se comparó la aplicación de diferentes protocolos de cría a juveniles de corvina (Argyrosomus regius), que es la especie objetivo de un programa de repoblación llevado a cabo en las Islas Baleares (Mediterráneo occidental). Se compararon siete dietas diferentes durante la fase de engorde para identificar cuáles de ellas podrían producir juveniles de buena calidad, de un tamaño dado y al menor coste. La mayoría de las dietas produjeron juveniles de calidad biológica adecuada en términos de crecimiento, condición del pez (estimada a partir de la rela...
