Abstract:The present study was conducted to investigate effects of stocking density on growth performances of gold fish (Carassius auratus) in hapas. Experiment was conducted for a month with three treatments where three stocking densities were T 1 (10 fry/hapa), T 2 (15 fry/hapa) andT 3 (20 fry/hapa) each having three replications which were selected randomly. In the present experiment hapa (3ft × 2ft × 2ft) with 1 mm mesh net was used. Gold fish fry having a mean body weight of 0.007 g were used in all treatments. Fishes were fed at the rate of 10% of their body weight containing 34.11% protein. Water quality parameters were monitored at 10 days interval and the ranges were -temperature 24.75 to 27.75 o C, dissolved oxygen 3.68 to 4.09 mg/L, p H 7.3 to 8.16, ammonia 0.3 to 1 mg/L, nitrite 0.01 to 0.03 mg/L, phosphate 0.6 to 1 mg/L and alkalinity 119 to 187 mg/L. At the growth performances were evaluated by comparing mean final body weight, specific growth rate and food conversion ratio. The present study showed that the gold fish fry in T 1 resulted the best mean final weight gain (1.188 g) followed by T 2 (0.834 g) and T 3 (0.686 g). The SGR ranged between 6.64 and 7.43% per day and FCR ranged between 3.56 and 4.12 with T 1 showing the lowest FCR. The survival rate (%) ranged between 76.67% to 85.67%. From the present experiment it was found that individual fish growth rate was decreased with the increase of stocking density.

“…In case of cyprinids larvae, too short periods of feeding with natural food lead to essential decrease in survival as well as growth rates (Wolnicki, 2005). In the majority of cases, 10 days is enough to prevent the negative effect of compound food offering (Wolnicki, 2005;Wolnicki et al, 2009). In the present study this period influenced positively the survival rate but it turned out not enough to prevent the slowest growth and deformities rate.…”

“…However, the growth rate of larvae of this species is very slow as compared to other cyprinids (i.e. Wolnicki, 2005;Wolnicki et al, 2009), which were able to reach c.a. 25 mm TL during 21 (Wolnicki and Myszkowski, 1999).…”

“…For that purpose, most commonly used techniques are: specially prepared and naturally fertilized ponds (Milstein et al, 2006;Śliwiński, 2009), net cages or recirculating aquaculture systems (i.e. Wolnicki et al, 2003;Wolnicki et al, 2006;Wolnicki et al, 2009). Fast developing cultures in closed systems are becoming increasingly widely used due to the possibility of full control of environmental and sanitary conditions (Blancheton, 2000) and economic effectiveness of production (Turkowski et al 2008).…”

In the current paper we present a method of rearing tench (Tinca tinca L.) larvae under controlled conditions, fed on dry food (Gemma and Perla) and Artemia nauplii or decapsulated cysts of Artemia. Tench larvae were obtained after artificial spawning by aid of Ovopel stimulation. Two experiments were conducted during which fish were divided into 4 groups (in duplicate) and placed in 30 dm 3 glass fish tanks set up in a recirculating system. The fish were fed ad libitum and reared for 25 days. Larvae were fed exclusively (experiment 1) or after 10 days (experiment 2) of receiving Artemia nauplii with two types of compound feeds and decapsulated cysts of Artemia. The best growth rate was observed in the control group fed on Artemia nauplii and in the group offered decapsulated cysts in both experiments. The highest survival rate, over 96%, occurred in the control group. A twofold worse survival rate was obtained in the group fed exclusively on dry food. Applied transition schedule had significant effect on survival rate among treatments, however it did not influence the percentage of body deformations occurring in groups receiving compound feed only. The results obtained indicate the necessity of applying gradual transition from live food to compound feed and the improvement of feeding schedules in common tench culture.

“…Production of stocking material based on reproduction, incubation and rearing under controlled conditions together with improvement of environmental conditions gives a possibility of protection of endangered fish species from river ecosystems Shiri Harzevili et al, 2003Krejszeff et al, 2008Krejszeff et al, , 2009Kucharczyk et al, 2008a,b;Targońska et al, 2008a,b;Żarski et al, 2008a,b;Wolnicki et al, 2009). The rearing of young fish under controlled conditions is the more effective, the more precisely the influence of environmental conditions on the body -relatively sensitive at that time -is determined (Wolnicki, 2005).…”

In recent years, despite a certain deceleration of the process, evident decrease or even extinction of many local populations of the majority of rheophilic fish species including dace Leuciscus leuciscus (L.), ide L. idus (L.), and chub L. cephalus (L.) -the only representatives of the genus Leuciscus in Polish ichthyofauna -has still been observed. Invariably, the major reasons for that situation are ) and chub L. cephalus (L.) were obtained from rivers belonging to the Pasleka River basin (northeastern Poland) and next transported to a hatchery for the purpose of conducting artificial reproduction. The obtained eggs were fertilized and next incubated under a variety of thermal protocols: slow gradual heating of water (M1), rapid increase in temperature at the end of incubation (M2), fluctuating temperature (M3) and two constant temperatures (optimum and sublethal). Variable thermal changes of water were also continued after hatching, up to the yolk sac resorption by larvae. During the study it was shown that relative to incubation at optimal temperatures (12.3°C for dace, 15.7°C for ide and 19.0°C for chub), thermal modifications had no clear influence on a decrease in survival rates (differences among regimes did not exceed 5%) and increase in developmental deformations (differences below 1.0%) observed among the hatched embryos. The duration of egg incubation and developmental rate increased with increasing temperature. In the systems with modified temperature the embryonic development of dace (from fertilisation to commencement of exogenous food intake) took from 9.5 to 22.5 days, for ide from 6.1 to 12 days and for chub from 5.0 to 10.5 days. The yolk sac resorption stage in the particular species occurred from 11.7 to 23 days for dace, 7.5 to 13.2 days for ide and 5.5 to 12.8 days for chub. Different time of hatching was also reflected in the level of ontogeny of hatched embryos. Among the fish hatched at modified temperatures the largest sizes, similar to those characteristic of fish incubated at optimum temperatures, were observed in individuals originating from variants where the temperature fluctuated. The developmental disproportions among the embryos of studied species originating from different thermal regimes observed at the time of leaving the egg shells were definitely larger than during the following development stages. This study also confirmed that the embryos of studied species can adapt to increasing water temperature due to global warming up to 19.0 (dace), 23.0°C (ide) and 27.5°C (chub). The obtained results are very important not only for practical purposes but also from physiological and ecological aspects.
