“…The absolute fecundity (from 164.6 to 208.3 9 10 3 eggs) of pikeperch recorded in this study is similar to the results reported by Demska- Zakes and Zakes (2002) and Lappalainen et al (2003). Also, size of eggs showed no difference with the previous studies (Horvath et al 1984;Schlumbenger and Proteau 1996;Lappalainen et al 2003).…”

“…The relative fecundity (from 88.0 to 144.6 9 10 3 eggs kg -1 ) of pikeperch obtained in this study is lower compared with Lappalainen et al (2003) (250 9 10 3 eggs kg -1 ) and to Schlumbenger and Proteau (1996) (200 9 10 3 eggs kg -1 ). The absolute fecundity (from 164.6 to 208.3 9 10 3 eggs) of pikeperch recorded in this study is similar to the results reported by Demska- Zakes and Zakes (2002) and Lappalainen et al (2003).…”

The aim of the present study was to study spawning stimulation in artificial reproduction of females pikeperch (Sander lucioperca L.) using ''Chorulon'' containing the human chorionic gonadotropin (hCG) and compare with ''Supergestran'' containing a mammalian GnRH ([D-Ala 6 ]GnRHProNhet) analogue. The females were divided into eleven experimental groups and injected with hCG at 250, 500, 750, and 1 000 IU kg -1 body weight (BW) and mGnRHa at 1, 2.5, 5, 10, 25, and 50 lg kg -1 BW. In all treatments, a single intramuscular injection of hormone was performed. Control group was injected with 0.9 % NaCl, 0.9 cm 3 kg -1 BW. The average percentages of ovulating females were 88.5 ± 12.3 and 80.8 ± 10.9 % in hCG-and mGnRHa-treated groups, respectively. The average diameter of eggs was 0.95 ± 0.06 and 0.98 ± 0.06 mm in hCG-and mGnRHatreated groups, respectively. Neither ovulation rate nor diameter of egg was statistically differed among hormonally treated groups. Statistical difference was observed only in hatching rate, where the average were 73.6 ± 14.4 and 50.6 ± 17.7 % in hCG and mGnRHa-treated groups, respectively. Among hormonally treated groups, the best results were observed in groups treated with hCG at 500 and 750 IU kg -1 and in groups treated with mGnRHa at 25 lg kg -1 . No ovulation was observed in the control group. This study indicated successful ovulation in pikeperch using a single intramuscular injection of hCG or mGnRHa analogue.

“…Before the spawning season of zander under natural conditions, when the size of ripe oocytes is the largest in the gonads, the value of GSI can reach 14-19% (Lappalainen et al, 2002). The relative fecundity which is defined as the number of eggs per 1g of female varies between 150 and 400 eggs on average (Lappalainen et al, 2002).…”

“…The relative fecundity which is defined as the number of eggs per 1g of female varies between 150 and 400 eggs on average (Lappalainen et al, 2002). However, there is no data about the GSI of zander females cultured in farm conditions.…”

In this study data on successful propagation of zander (Sander lucioperca L.) from several spawning seasons are evaluated. Propagation was based on stripping of spawners after hormonal induction and rearing of fry in artificial ponds. Fish were injected with acetone-dried carp pituitary extract at a dose of 4.0 mg/kg homogenized in a fish physiological saline. When ovulation was detected, the eggs were stripped and weighed. Eggs were collected from each ovulated female and fertilized with milt from the male. Stickiness of zander eggs was removed before transferring them into Zuger jars. Data collected from four consecutive spawning seasons were analyzed statistically calculating individual and group-based pseudogonadosomatic index (PGSI) values. Reproduction capacity assays were grouped on the basis of three aspects: (1) examination of differences between years, (2) within a reproductive season, and (3) examination of the effects of females' size. During the four-year trial period eggs were gained from 121 hormonally treated females, 64.7% of the total 187. Based on the data of the investigated period the mean PGSI was 10.7%. At 95% significance level PGSI data of different years were considered to be similar. There were no significant differences between PGSI data collected from different periods of the reproductive season. Previous findings on the positive correlation between the amount of stripped eggs and body weight of females were confirmed (r 2 =0.103). Correlation was not justified between PGSI and body weight (r 2 =0.002). Advanced rearing of zander fry in a 2.0 hectare pond was carried out in six consecutive years. Before stocking the nutrient level of the pond was increased by organic manuring and the Copepods were eliminated by insecticides. To prevent cannibalism, four weeks after stocking the advanced fry of zander were harvested. On the basis of the results from six consecutive years, after rearing of advanced fry in a shallow, 2.0 hectare rearing pond for four weeks, the mean survival rate was 13.4±4.37% (mean±SD). By considering our results, breeders can calculate their hatchery's and pond's production in advance. These results will also be helpful in calculating the total weight of broodstock which must be held in order to produce a specific number of advanced fry.

“…Higher temperatures can be expected to increase the growth rates of many fish species in the Baltic (MacKenzie et al 2007 and reference therein), implying a change in weight at age. Faster growth in turn causes earlier maturity in pikeperch populations adapted to warmer conditions (Lappalainen et al 2003). Therefore the Pärnu Bay pikeperch stock might be less sensitive to the catch of small fish in a future warmer climate.…”
