“…This information is very important for fish producers to illustrate the optimum period of the reproductive season. There are a few studies showing the effect of the season on the reproductive performance of females in different fish species such as perch Perca fluviatilis (Kestemont et al, 1999;Migaud et al, 2001Migaud et al, , 2004, common carp Cyprinus carpio (Kucharczyk et al, 2008) and walleye Stizostedion vitreum (Malison et al, 1998). The present results showed that the highest reproductive performance of females was in the middle of the reproductive season and the lowest at the beginning and end of the season.…”

Growth and survival rates (specific growth rate -SGR; survival rate -S) of Barbus barbus L. were recorded in captivity during three years from the larval period (final body weight -W = 0.2 ± 0.03 g; SGR = 13.6 ± 1.1%/day and cumulative survival -S = 76.0 ± 2.5%) to the first reproductive season (W = 62.55 ± 13.5 g; SGR = 0.89 ± 0.05%/day; S = 59.3 ± 1.5%). Final body size and SGR were compared between both sexes. Females reached the significantly higher growth rate (SGR = 0.84 ± 0.01%/day) compared to males (SGR = 0.77 ± 0.01%/day). Early puberty was observed in 17 and 32 months old males and females, respectively. Multi-stripping activity was found out in both sexes during the first reproductive season. In total, 20%, 25.8%, 30.3%, 14.6% and 9% of females were stripped once, twice and three, four and five times, respectively. But all males produced sperm during the entire reproductive season. The highest and the lowest egg production was recorded in the middle (April) and at the beginning (March) of the reproductive season (2155 ± 925 vs. 1279 ± 298 eggs per stripping). The highest and the lowest sperm production was observed at the beginning (March) and at the end (May) of the reproductive season (7.9 ± 0.08 × 10 9 vs. 1.9 ± 0.06 × 10 9 per stripping).

“…More recently, we have shown that environmental manipulations and hormone injections can be successfully used to greatly advance spawning in walleye (Malison et al 1994b; also see Table 1). To accomplish this, wild adult walleye were captured in the autumn and held in outdoor ponds.…”

The walleye (Stizostedion viweum) is a North American mesothermal freshwater teleost that spawns once each year in early spring. Walleye spawn randomly over suitable substrates and d o not provide any parental protection for eggs or juveniles. The majority of gonadal recrudescence in adult male walleye occurs in the autumn, and walleye testes contain large numbers of viable spermatozoa from late autumn through the spawning season. Adult female walleye exhibit group synchronous ovarian developmcnt, and similar to males, the majority of gonadal development occurs in the autumn. Evidence suggests that 17a,20P-dihydroxyprogesterone is the maturational steroid in this species. Simple environmental manipulations coupled with injections of human chorionic gonadotropin can be used to advance spawning in walleye by up to 12 weeks. To spawn and propagate walleye, hatcheries in North America use a wide range of methods that have been developed to meet the needs and conditions present at specific facilities. IntroductionFor many years, walleye (Stizostedion uitreum) have been propagated extensively to support and augment both recreational and commercial fisheries in North America (Conover 1986). More recently, this species has been evaluated for its potential for commercial food fish aquaculture in this region. This paper will review the reproductive biology of walleye, methods to induce and control spawning, and procedures commonly used to fertilize and incubate eggs.

The aim of this study was to determine the effectiveness of out‐of‐season spawning of cultivated pikeperch (fish that were reared from the larval stage in re‐circulating systems and fed commercial feed exclusively) stimulated hormonally with human chorionic gonadotropin (hCG). The impact of fish age (2+ and 3+) and hormone dosage [200 or 400 IU hCG kg−1 body weight (BW)] on spawning was analysed and expressed as the share of stripped females, commercial fecundity (% BW) and survival of embryos until the eyed‐egg stage (EES index). The possibility of utilizing changes in female pikeperch body weight (CBW index) that are observed following hormone injections as an additional indicator for determining maturity was also investigated. The age and hormone dosage were not noted to have a significant impact on the number of stripped females (≥80% on all groups), the latency period (90–100 h), commercial fecundity (11.3–13.3% BW) or the values of the EES index (61–73%; P>0.05). The mean value of EES from the 3+ age group females was higher than that in the 2+ females, and the interaction between the tested factors (fish age and hormone dosage) wasstatistically significant (P<0.05). In the fish from the control group (injected with a 0.9% NaCl solution), no progress was noted in the maturation of oocytes and no eggs were obtained from any female. It was noted that these females lost BW over the course of the subsequent 24 h of the measurements (P<0.05). In the groups of females that were stimulated hormonally, the opposite phenomenon was observed; in these groups, the CBW index increased significantly between 48 and 96 h following hormone injection. The value of the CBW index was not noted to have been statistically significantly determined by either hormone dose or fish age (P>0.05). The regression equations that described the dependence between CBW and the oocyte maturity stage were highly significant statistically, and the determination coefficient R2 assumed a value of 0.76. The most significant increase in BW was related to the oocytes achieving maturity stage III. The BW of pikeperch females with oocytes in this stage was 103% higher than the initial BW. This might be a valuable and useful tool for determining maturity in females of this fish species.
