“…On the other hand, after this week the wedge sole adapts well to captivity, easily accepting the first meal offered. These characteristics make spawns possible in less than 1 year, as opposed to the situation of the common sole (Solea solea Linnaeus, 1758) (Devauchelle et al 1987). The mean size of the captured fish, 15.5 ± 0.2 cm, exceeded that of first sexual maturity in the Gulf of Cadiz, 14 cm (Vila and Jiménez 2002).…”

The wedge sole is a target species in the fisheries of the Gulf of Cadiz (Spain). Having reared them to commercial size, we have studied reproduction and breeding in captivity of the wedge sole in this work here. The breeders adapt easily to captivity, and they can spawn in less than 1 year in captivity. The relative fecundity is relatively high, 1.06-2.33 Á 10 6 eggs kg À1 per spawning season (mean 1.6 ± 0.1). Larval SGR is high, 7.2 ± 0.2% day À1 (range 5.8-9.1), similar to other cultured flatfish species. In 1 year, some individuals reach market size and can release eggs, registering SGRs of 1.39-1.66% day À1 (mean 1.56 ± 0.01). This species presents some very different characteristics with respect to other farmed flatfishes (turbot, halibut and Senegal sole, mainly), so that it is necessary to develop new techniques to optimise its cultivation. In the present work, the first results are presented on the biology of the wedge sole in captivity.

“…As marine fish culture is a relatively new endeavor , compared to land animal culture , other concerns have been considered more pressing than broodstock management. Kjorsvik et al (1990) Devauchelle et al (1987) reported on the same parameters, also over a 12 year period, on the spawning of sole in the laboratory. Berlinsky et al (1996) reported on the induced spawning of southern flounder using gonadotropin analogues.…”

“…Asia, but the importance of successful first feeding to larval survival is well documented in turbot (Anthony, 1910;Dhert et al, 1994;Jones, 1973;Jones et al, 1981;Minkoff & Broadhurst, 1994;Planas, 1994), striped mullet (Eda et al, 1990;Tamaru et al, 1994), halibut (Naas et al, 1992), sole (Devauchelle et al, 1987), spot (Govoni, 1981), winter flounder (Buckley et al, 1991), southern flounder (Daniels et al, 1996), and plaice (Shelbourne, 1964;Wyatt, 1972), among many others.…”

Investigations into the causes of early larval mortality in cultured summer flounder (Paralichthys dentatus L.)

1999

Experiments were conducted to investigate larval mortality in cultured summer flounder during the first two weeks after hatch.The importance of feeding success,parentage, addition of algae, water quality, and the microbial community to mortality during this period were investigated. Larvae were raised in 2-L bowls at initial densities of 50 and 75/L with light aeration, 12L:12D photoperiod, and regular 1-L water changes.In all experiments mortalities were recorded and removed daily. In the first two experiments daily samples of larvae were taken to assess feeding success and to relate that to survival.The second experiment investigated the effects of both feeding success and the addition of algae to larval culture bowls on larval survival. The third experiment investigated the effects of water quality and bacterial load on survival during the experimental period. The first two experiments indicated that failure to establish .feeding is probably not the cause of catastrophic mortality of the larvae, although a statistical relationship existed between feeding incidence and survival in two of six cases. High variability (34 ± 38% n=82) in survival was seen in the first two experiments (both within and between parental crosses) suggesting that catastrophic mortalities were due to rearing conditions rather than gamete quality. The addition of algae to larval cultures increased survival from 13 ± 24% (n=33) during the ii ·f i rst experiment to 46 ± 39% (n=49 ) during the second experiment. The final experiment indicated that larval mortality was not linked to the measured microbial or water quality conditions. The relationship between the percentage of floating eggs at time of fertilization and survival at 10 DAH was found to be not significant, providing further evidence that gamete quality was not as important as rearing conditions in these experiments.iii ACKNOWLEDGMENTS

“…It also may be shifted by maintaining the animal under modified photoperiods (Carrillo et al, 1989;. Moreover, it has been found that exposure of female fish to modified photoperiod affects the rate of maturation and timing of spawning (Carrillo et al, 1989;Barnabè and Paris, 1984), while little loss in egg quality in terms of survival of eggs and fry or of fecundity was observed in photoperiodically advanced broodstock (Devauchelle et al, 1987;Carrillo et al, 1995). In contrast, poorer fecundity and egg survival have been found in photoperiodically delayed fish (Zanuy et al, 1986;Devauchelle and Coves 1988;Carrillo et al, 1991).…”
