“…The portion of cannibals in a population can reach 33% (Klein Breteler 1989) or even 41% (Molná r et al 2004) in the case of pikeperch. Somewhat lower values have been reported for walleye (4-25%) by Chesire and Steele (1972), Nagel (1976) and Kuipers and Summerfelt (1994). In our experiment, the incidence of cannibals was relatively low, and it was not the main reason of mortality.…”

The efficiencies of four feeding methods were compared in the transition period from live food to dry feed in pikeperch (Sander lucioperca). Pond-nursed fry were trained to artificial feed without a transition (Group P) and with a transition, using a combination of dry feed and different kinds of live food-Chironomus larvae (Group C), Tubifex (Group T) and Daphnia (Group D)-during a 12-day-long trial. The ratio of dry feed for the transition groups was increased from 0 to 100% in 3-day intervals. The highest specific growth rates and condition factors were detected for Group C (4.2%, 1.46 ± 0.5) and Group T (4.2%, 1.48 ± 0.6), respectively. The survivalpercentages of the groups were as follows: 86.7 ± 9% (Group C), 78 ± 4% (Group T), 52 ± 1.4% (Group D) and 41 ± 9% (Group P). The rate of cannibalism ranged between 6.3 and 13.7% during the transition period. Larger-sized fish seemed to learn more rapidly to accept dry feed than their smaller counterparts.

“…In an experiment carried out on walleye, Kuipers and Summerfelt (1994) achieved a 68-85% survival in a 29-day long weaning period, while earlier authors reported 40-80% losses (Chesire and Steele 1972;Nagel 1976).…”

“…Sanderson (1974) suggested that minimum size of S. vitreum fry fed artificial feed should be around 35 mm, and according to Nickum (1978) it should range from 35 to 75 mm. It is often stated that the best results of rearing are obtained when initial fish body size exceeds 50 mm (Cheshire, Steele 1972, Nagel 1985, Nickum 1978, Kuipers, Summerfelt 1994). On the other hand, too long pond rearing causes increased fish mortality due to cannibalism and starvation.…”

Abstract. Studies were carried out on the effect of initial size summer pikperch fry, Stizostedion lucioperca, (two size groups), water temperature (22 and 24°C), and food type (zooplankton or artificial feeds) upon the results of rearing in controlled conditions. Weight and total length of the fish at the beginning of the experiment amounted respectively to 0.25 ± 0.06 g and 32.9 ± 2.7 mm (group S), 0.53 ± 0.06 g 39.4 ± 1.6 mm (group L). No significant effect of the initial fish size and water temperature on fish survival and losses due to cannibalism was bserved in fish which fed on zooplankton (p > 0.05). Statistical analysis revealed significant effect of initial fish size (p = 0.0011) as well as water temperature (p = 0.0001) on the survival in the groups of fish reared on artificial food. These fish attained bigger size (body weight and length) than fish in the control group (feeding on live zooplankton) (p < 0.05). Temperature had no effect on growth rate of the fish, those reared on artificial as well as natural food.

“…Selon Cheshire et Steele (1972), le doré connaît deux périodes de pointe de cannibalisme, la première survenant dans la semaine suivant réclosion et la seconde au milieu de l'été, alors qu'ils transitent d'une alimentation à base de zooplancton vers une alimentation â base de poissons.…”
