“…Due to the opaqueness of the juveniles’ body, specimens from sample C after anaesthetization were radiographed (Koumoundouros et al , 2000) and examined for the existence of vertebral malformations. All specimens with deformities in the cephalic region, fins or vertebral column (Koumoundouros et al , 1997, 2001, 2002, 2004; Sfakianakis et al , 2004, 2006), as well as those with damaged body parts due to sampling manipulations, were excluded from shape analysis.…”

To exam whether the temperature experienced by fishes at early developmental stages can influence their phenotype at subsequent stages, the model species used, European sea bass Dicentrarchus labrax was subjected to water temperatures of 15 or 20°C during the half-epiboly stage until the metamorphosis. Meristic and morphometric characters at three different stages, well after the end of the thermal treatments, were explored. Body shape and most of the meristic characters were significantly affected by the environmental temperature during their early life stages. Fish body shape at 15°C tended to be more slender than at 20°C. The dorsal spines and soft rays, the pectoral lepidotrichia and caudal dermatotrichia were significantly affected. Phenotypic differences due to the two thermal regimes are discussed in terms of their functional meaning during the transition from the planktonic to the littoral niche.

“…During the early developmental stages, fish are highly sensitive to environmental variables. As illustrated in previous studies, these stages are characterized by low larval survival, high incidence of skeletal deformities, nutritional disorders, extreme sensitivity to handling stress and frequent pathological outbreaks (Bermejo-Nogales et al, 2007;Koumoundouros et al, 2004).…”

“…Those stages are characterized by low larval survival, high incidence of skeletal deformities, nutritional disorders, extreme sensitivity to handling stress and frequent pathological outbreaks (Rueda and Martinez 2001;Koumoundouros et al 2004;Bermejo-Nogales et al 2007). Fish larvae shall be considered a transitional stage in which both ontogeny and growth result into substantial changes in the structure, physiology, size and body shape of the specimen (Gisbert et al 2009).…”

Digestive enzyme activities were analysed in turbot (Scophthalmus maximus) from hatching until 60 days after hatching (DAH). Trypsin sharply increased to the climax at 17 DAH and decreased until 31 DAH followed by a stable level thereafter. Amylase was determined at 4 DAH, reached the maximum value at 19 DAH and declined sharply to 39 DAH and remained at a low level thereafter, suggesting the carbohydrate component should remain at a low level in formulated diets. Pepsin was detected at 9 DAH and increased to 34 DAH and then remained at a stable level. The above results revealed pancreatic enzymes are no longer main enzymes for food digestion after the formation of functional stomach. Leucine-alanine peptidase (Leu-ala) and alkaline phosphatase (AP) and leucine aminopeptidase N (LAP) were found in newly hatched larvae. Both AP and LAP activities markedly increased to 23 DAH, decreased abruptly to 50 DAH and increased gradually to 60 DAH. Leu-ala reached the plateau from 23 to 39 DAH, followed by a decline to 46 DAH and an increase until 60 DAH. The brush border membrane (BBM)-bound enzyme activities increased from 30% at 31 DAH to 81% at 38 DAH of the total activities, indicating the maturation of intestinal tract.
