“…Some evidence suggests that general activity or vertical migratory activity declines in starved larvae of several species (Laurence 1972, Blaxter & Ehrlich 1974. Moreover, starvation leads to decreased growth rates (Ehrlich et al 1976, Yin & Blaxter 1986, slower development (Kamler et al 1990), and changes in behaviour for energy-saving purposes (Munk 1995, Ross et al 1996, Chick & Van den Avyle 2000, Skajaa et al 2004). Thus it is expected that larvae with low nutritional condition will be smaller and less developed in sensory and locomotory capacities than well-fed larvae.…”

Body condition in larval fishes is an important determinant of survival in the natural environment. However, few studies correlate body condition with behavioural traits critical for survival, such as swimming performance. In the present study, we compared normally fed larvae of gilthead seabream Sparus aurata Linnaeus, 1758, at various intervals post-hatch with larvae which were starved for 1 to 3 d (for U crit ) or 2 d (for swimming endurance). Feeding treatment (fed and or unfed) had no effect on the relationship between U crit and larval size. However, in the endurance experiment, fed individuals swam twice as far as unfed larvae (19.7 km for fed larvae and 9.5 km for unfed larvae). The RNA/DNA ratio was higher in fed larvae in the U crit experiment, but significant effects were only detectable after a 3 d period of starvation. Fulton's condition factor was significantly higher in fed larvae in the endurance trial, which suggests that growth (in weight) of starved larvae was affected by long-term swimming. Taken together, these results suggest that for aging and orientation behaviours (activities in which critical speeds might be involved) are not affected by reduced feeding over a few days, but that sub-lethal effects of starvation may affect dispersal potential (for which endurance swimming is critical) and therefore compromise subsequent recruitment to the adult population.KEY WORDS: Gilthead seabream · Swimming performance · Nutritional condition · Sub-lethal effects · RNA/DNA ratio · Fulton's condition factor Resale or republication not permitted without written consent of the publisher

“…The two main mortality agents acting upon marine fish larvae are predation and starvation (Bailey and Houde, 1989). These factors are not independent, as starvation leads to a decreased growth rate (Yin and Blaxter, 1986), slower development (Kamler et al, 1990) and changes in behaviour (Sogard and Olla, 1996;Chick and Van den Avyle, 2000). Larvae with a low nutritional status will consequently be smaller, weaker and less developed with regard to sensory and locomotory capacities than well-fed larvae of the same age, thus being more susceptible to predation (but see Billerbeck et al, 2001).…”

SUMMARY: Food availability can affect larval survival directly through starvation and indirectly through the effects on larval growth rate, swimming performance and vulnerability to predators. In the present study we evaluate the effects of starvation on growth, nutritional condition and swimming behaviour of the Senegalese sole (Solea senegalensis) throughout ontogeny (8 to 14 days after hatching). Biochemical analysis (RNA/DNA ratios) and behavioural experiments (critical swimming speed, U crit ) were conducted on larvae reared under 3 feeding treatments: fed ad libitum, deprived of food for 48 hours and deprived of food for 96 hours. Growth was significantly affected by feeding treatment, while only slight decreases in RNA/ DNA ratio and swimming performance were registered. Late stage larvae of the three feeding treatments had slower critical speeds than the pre-flexion and flexion stages, which is probably related to the benthic lifestyle acquired by the species at the end of the larval period. These physiological and behavioural changes are in accordance with previous results, which show that flatfish larvae are more resistant to starvation than pelagic species and that they become less active later in development.Keywords: Senegalese sole, Solea senegalensis, feeding treatment, starvation, RNA/DNA ratio, critical swimming speed, U crit , ontogeny. RESUMEN: Influencia del ayuno sobre el comportamiento natatorio crítico del lenguado senegalés Solea SenegalenSiS y su relación con el cociente RNA/DNA durante la ontogenia. -La disponibilidad de comida puede afectar la supervivencia larvaria directamente a través del ayuno e indirectamente a través de los efectos sobre la tasa de crecimiento larvario, actividad natatoria y vulnerabilidad a los predadores. En el presente estudio evaluamos los efectos del ayuno sobre el crecimiento, condición nutricional y comportamiento natatorio del lenguado senegalés, Solea senegalensis, durante la ontogenia (8 a 14 días post-eclosión). Se llevaron a cabo análisis bioquímicos (RNA/DNA) y experimentos de comportamiento (velocidad crítica de natación, U crit ) sobre larvas mantenidas bajo 3 condiciones de alimentación: alimentadas (tratamiento ad libitum), ayuno a corto plazo (hasta 48 h sin alimentación) y ayuno a largo plazo (hasta 96 h sin alimentación). El crecimiento varió significativamente según el tratamiento alimentario, mientras que el cociente RNA/DNA y la capacidad natatoria mostraron únicamente una ligera disminución. En los tres tratamientos alimentarios los estadios larvarios más avanzados mostraron velocidades críticas más bajas cuando se compararon con las de los estados de preflexión y flexión, lo que está probablemente relacionado con el estilo de vida bentónica adquirido por la especie al final del periodo larvario. Estos cambios fisiológicos y de comportamiento concuerdan con resultados previos que muestran que las larvas de peces planos son más resistentes al ayuno que las de especies pelágicas y se vuelven menos activas con el desarrollo.Palabras clave: le...

The osteological development of the vertebral column and fins in shi drum Umbrina cirrosa was studied in order to improve knowledge for its introduction in Mediterranean aquaculture. The osteological development was studied in 171 individuals, of total length (L ) from 2·7 to 30·2 mm that were reared under the mesocosm technique. Vertebral ontogeny starts at 3·4 and 4·0 mm L , with the formation of the first cartilaginous neural and haemal arches, and spines, respectively, and is completed with the full attainment of epicentrals (12·5 mm L ). The formation of vertebral centra occurs between 4·1 and 7·4 mm L . Pectoral supports are the first fin elements to develop (3·0 mm L ), followed by those of the caudal fin (3·8 mm L ), pelvic fin (3·9 mm L ) and finally by those of the dorsal and anal fins (4·5 mm L ). The caudal fin is the first to develop fin rays and attain the full count of principal fin rays (4·5-6·8 mm L ), but the last to be fully completed with the formation of procurrent fin rays (6·9-17·5 mm L ). The next fins starting to present rays are the dorsal (5·3 mm L ) and the pectoral fins (5·6 mm L ), while the anal and pelvic fins are the last (5·7 mm L ). Following the caudal principal fin rays (6·8 mm L ), the dorsal, anal (6·9 mm L ), pelvic (7·4 mm L ) and pectoral fins (9·8 mm L ) are the next with fully completed ray counts. Aggregation of qualitative changes, such as the appearance of cartilages, the beginning and the complement of the ossification process and the full complement of elements in U. cirrosa were measured as cumulative frequency counts. These measurements reveal three ontogenetic intervals: one very developmentally active period during early life stages (from 3 to 5·9 mm L ), a second slower developmental period (from 6·0 to 8·9 mm L ) and finally a period of ontogeny more focused on structure refinement up to metamorphosis and settlement (>9·0 mm L ).
