“…The incubation of sichel eggs took place in water of the optimal temperature (19.0 ± 0.1°C) (Kujawa, Furgała‐Selezniow, Mamcarz, Lach & Kucharczyk ), in five separate, close recirculation systems (Kujawa, Mamcarz, Kucharczyk & Skrzypczak ), containing water of the following salinity: 3, 6, 9, 12 and 15 ppt. Pro‐Reef marine salt by Tropic Martin was used to achieve the required salinity of water.…”

The purpose of this study was to analyse the influence of water salinity on the incubation of eggs and growth of the larvae of sichel Pelecus cultratus (L.) under controlled conditions. The following water salinity was considered: 3, 6, 9, 12, 15 and 0 ppt for the control. The eggs incubation time depended on the water salinity, lasting from 56.3°D [9 ppt] to 107.7°D [0 ppt]. The higher water salinity, shorter the incubation time. The highest survivability of larvae was obtained in water of the salinity equal 3 ppt and in freshwater, where respectively 87% and 84% of the larvae survived. No hatched larvae were obtained in water of the salinity of 12 and 15 ppt, as all embryos died during the experiment. Larvae were reared up for 21 days. The final body weight, depending on the water salinity, reached from 43.5 mg [9 ppt] to 74.6 mg [3 ppt], at the respective body lengths of 19.3 mm and 23.2 mm. The highest body gains and lengths of larvae were observed in water of the salinity of 3 ppt. The lowest survivability of sichel larvae occurred in water of the salinity 9 ppt, where it was only 53.2%. The survivability of larvae in freshwater and water of the salinity of 3 ppt was quite similar: 96.2% and 95.6% respectively. Water salinity degree of 12 and 15 ppt appeared to be lethal for both embryos and larvae of the sichel.

“…Throughout the whole rearing period, the daily light and darkness cycle was fixed, with 12 hours of day and 12 hours of night. The water temperature was 25.0±0.5ºC (± standard deviation) (Kujawa et al 2015), which was found as one from the thermal optimum range for sichel embryonic development. The concentration of water dissolved oxygen ranged from 7.1 to 7.7 mg O 2 dm -3 , while the value of pH was from 7.2 to 7.4.…”

“…The flow of water in a jar was regulated so that it mixed gently the whole contents of the jar. The spawn was incubated for 5 days in water of the temperature 18.5°C (Kujawa et al, 2015), which was found as an optimal temperature was sichel embryonic development. Larvae were allowed to hatch for one day since the first hatched individuals were spotted.…”

“…Such methods have been designed for rheophilic cyprinid fish , including asp , barbel (Wolnicki, Górny, 1995b;Kujawa et al, 1998b), common nase , ide (Wolnicki, Górny, 1995a;Jamróz et al, 2008;Kucharczyk et al, 2008), dace and chub (Żarski et al, 2008). Larvae of cyprinid fish are extremely responsive to a number of factors which influence their physiological and health condition (Peňáz et al, 1989;Korwin-Kossakowski, 1992;Nowosad et al, 2013). They are particularly sensitive to any shortage of food during the transient stage between endogenous nutrition (nutrients stored in the yolk) to exogenous foraging (zooplankton).…”

Larvae of sichel Pelecus cultratus (L.) were reared up on natural food (Artemia sp. nauplii), after a certain time replaced by dry feed (Perla -Skretting). The rearing was conducted in aquaria of the capacity of 50 dm 3 each working in a closed, water recirculation system. The sichel larvae were reared up for 21 days in five nutrition groups: P21 -dry feed only, A4P17 -4 days of Artemia larvae followed by 17 days of dry feed; A8P13 -8 days of Artemia nauplii followed by 13 days of dry feed; A12P9 -12 days of Artemia larvae followed by 9 days of dry feed, and A21-Artemia nauplii throughout the whole experiment. The assessment of the effect of substituting natural food with feed was based on the size reached by larvae, survivability, relative growth rate of individual fish larvae and body condition. The larvae fed on the dry feed and the ones which first received Artemia nauplii for the first 4 to 8 days presented the smallest gain, which suggests that natural food should be given to sichel larvae for at least the first 12 days of rearing

“…However, increasing attention is now being paid to conservation of biological diversity through rebuilding populations of endangered species and their populations. These activities require effective protocols for artificial spawning and initial rearing of stocking material concerning different aspects of these biotechnological procedures (Kowalski et al, 2003;Augustyn, 2004;Kucharczyk et al, 2008;Targońska and Kucharczyk, 2011;Targońska et al, 2011a, Demény et al, 2012Żarski, 2012;Nowosad et al, 2014;Kujawa et al, 2015).…”

This study presents the results of inducing spermiation and ovulation of dace (Leuciscus leuciscus L.) spawners collected from different parts in of Poland. Artificial reproduction was performed using carp pituitary homogenate (CPH), human chorionic gonadotropin (hCG), agents containing a GnRHa with a dopamine inhibitor supplement (Ovopel and Ovaprim, GnRHa combined with metoclopramide) and GnRHa alone conducted during the spawning season. Males from the control group produced similar volumes of semen and sperm motility as fish after hormonal preparation application. Stimulation of ovulation by manipulation of environmental factors as well as by GnRHa alone did not trigger ovulation within 70 hrs following administration of a resolving injection, but did cause GV migration. Applying GnRHa with the dopamine inhibitors or CPH produced 80-100 % ovulation in females. The differences in reproduction between fish populations were reflected in ovulation synchronization, which was highly variable among populations or embryo survival. The fish stimulated with CPH ovulated several hours earlier than those injected with GnRHa combined with a dopamine inhibitor. The data obtained in the present paper could be applied to the production of the rheophilic cyprinid stocking process and, consequently, could form an important tool in the conservation of endangered or over-exploited finfish populations.
