“…Abnormal eggs are capable of producing viable larvae in yellowtail flounder Limanda ferruginea (Avery and Brown, 2005). In contrast with our results, numerous studies used asymmetry as an important indicator of poor egg quality (McEvoy, 1984;Devauchelle et al, 1988, Kjørsvik et al, 2003. In cold shock groups, there was significant negative correlation between asymmetric cell percentage and embryo viability.…”

“…There is much supporting evidence, for example, that abnormalities increase the susceptibility of eggs to bacterial contamination (Hansen and Olafsen, 1989;Pavlov and Moksness, 1993) or pollution (Longwell et al, 1992). A positive correlation was detected between normal blastomeres morphology and hatching success (McEvoy, 1984;Devauchelle et al, 1988;Kjørsvik et al, 1990Kjørsvik et al, , 2003Pickova et al, 1997). There are few studies about cleavage patterns, which exhibit details of blastomere morphology (Shields et al, 1997;Rideout et al, 2004;Avery and Brown, 2005).…”

Fertilization and embryonic survival rates and cleavage pattern were examined to test the effects of triploid induction in the Black Sea turbot (Psetta maxima). Fertilization rates were similar between cold shock and control groups, but the incidence of 4 different blastomere malformations were higher in cold shock group than that of control group. A positive linear correlation was detected in between normal blastomere morphology and embryo viability in all treatment groups. Except blastomere asymmetry, no other morphological abnormalities found correlated with embryo survival. Blastomere asymmetry showed negative linear correlation with embryo survival only in cold shock group. The results of the study demonstrated that blastomere morphology could be used in assessing egg quality and the negative effects of triploid induction in the Black Sea turbot.

“…Additional consideration must be made of handling stress and the effects of stripping frequency on milt quantity and quality (Suquet et al, 1992b). Ability to coordinate time of stripping with ovulation in flatfish is important so that eggs do not become over-ripened or released freely in the holding tank (Devauchelle et al, 1988). Use of GnRHa implants lowered sperm density in Atlantic halibut (Tvedt et al, 2001), whereas hormonal treatments used to induce ovulation in female summer and southern flounder were ineffective in inducing spermiation (Watanabe and Carroll, 2001).…”

The subject of reproductive potential of fish populations is dominated by studies on the female gender. Studies on male reproduction are relatively few, but have increased in number during the previous decade. The objectives of this contribution were to describe and quantify the reproductive traits that make up the viable sperm production of a population. Some of these reproductive traits were easily measured from wild fish (e.g., mature testes weight), and others were more easily measured on captive fish (e.g., fertilization potential and sperm motility). Results of laboratory and field studies were then integrated to generate estimates of viable sperm production of a fish stock. A number of experimental protocols have been employed over the years to assess male fertility. The strengths and weaknesses of the different experimental approaches were reviewed and appropriate recommendations given towards establishing standardized protocols. Although the review is broad in nature, and includes references to a number of marine fishes, it concentrated on exploited species that occur in the North Atlantic and Baltic Sea within the taxonomic groups gadoidae, pleuronectoidae and clupeidae (Clupeiformes). In addition, published data on male reproductive traits of species in these taxa were tabulated and summarized. The terms of interest included sex ratio, maturity state, testes weight, sperm fertilization potential (artificial fertilization and paired mating), sperm density, sperm motility and paternal effects on early life history traits.An equation for determinate spawners was described that quantifies a population's viable sperm production using data on adult body characteristics and associated quantity and quality of sperm. The equation was used to establish time series of viable sperm production for Atlantic cod (Gadus morhua) of Newfoundland and Labrador. Results indicated on average 1 600 billion viable sperm were released to produce one recruit at age 3 years but with substantial variation among years in relation to changes in stock composition and growth as well as stock size. Distinct peaks in the number of viable sperm in 1981 and 1986 corresponded to distinct peaks in the number of age 3 recruits in those same years.

“…Significant declines were observed for hatching rates according to increasing or decreasing of 14°C incubation water temperature. Since high temperature accelerates embryonic development (Jones, 1972;Kuhlmann & Quantz, 1980;Devauchelle et al, 1988) there were some problems about fulfilling the embryonic development, in addition to this some larvae died particularly during gastrula phase. So, the lowest hatching rate was recorded at 18°C.…”

In this research, the effects of different temperatures (8, 10, 12, 14, 16 and 18°C) and salinities (5, 10, 15, 18, 20, 25, 30, 35 and ‰40) on the development of turbot (Psetta maxima) eggs were investigated in triplicates. Broodstock produced in CFRI were used in this research. Fertilization, hatching, anomaly rate and larvae length were measured. Time dependent embryonic development were observed.Embryonic development was completed in each temperatures. It is observed that water temperature has significant effects on fertilization, hatching, anomaly and larvae length (P<0.05). Regression analysis showed that there was a negative correlation between the embryonic development and the water temperature of incubation. Time for hatching at 8 and 18°Cwere 2552 hour/degree and 1350 hour/degree, respectively. Better fertilization rate were obtained in salinities of ‰18, ‰20 and ‰25, respectively. Fertilization was not succeeded in the salinity values of 5‰ and ‰10. The anomaly rate in the salinity values of 15‰ and 40‰ was higher then in accordance with other salinity values.According to result of this study, to get high fertilization and haching rate and low abnormality for Black Sea Turbot, water temperature and water salinity were found as 14°C and ‰18, respectively.
