“…Our results differed from those obtained when rearing larger pikeperch (>100 g) in which larger feed pellet sizes increased final body weight variation coefficients (Zakêoe et al 2013, Mattila andKoskela 2017). The body weight variation coefficient in this study (17.3-32.0%) was lower than those noted in other studies on pikeperch with similar initial body weights (Wang et al 2009), but they were similar to results reported in other studies (Koz³owski et al 2010(Koz³owski et al , 2014.…”

“…The values of SGR obtained in experiment I were similar to those published by Molnár et al (2004) for juvenile pikeperch with an initial body weight of 0.91 g at 23.0°C. The SGR values in experiment II (3.06-3.70 % d -1 ) were higher than those reported by Koz³owski et al (2010) for fish with a BW i of 4.4 g (SGR 2.62-2.70 % d -1 at 20.0°C) and Wang et al (2009) for pikeperch with a BW i of 6.4 g (SGR 1.2-2.0 % d -1 at 20-28°C), while they were similar to those noted by Koz³owski et al (2014) for pikeperch with a BW i of 6.1 g at 24.4°C ). In experiment III, SGR values ranged from 2.54 to 2.81 % d -1 and were twice as high as those reported by Schulz et al (2005) for pikeperch with a BW i of 15.2 g at 22.6°C ).…”

“…Water flow was 9 l min -1 in experiment I and 12 l min -1 in experiments II and III. The daily feed ration was determined according to previous studies (Koz³owski et al 2010(Koz³owski et al , 2014 at 4% of fish biomass per day for experiment I, 3% for experiment II, and 2% for experiment III. The fish were fed Aller Performa Ex (Aller Aqua, Denmark) commercial sinking feeds (Table 2).…”

Three 28-day experiments were performed to assess the impact of two sinking feed pellet sizes (0.5–1.0 and 0.9–1.6 mm for experiment I, 0.9–1.6 and 1.3–2.0 mm for experiment II, and 1.3–2.0 and 1.6–2.4 mm for experiment III) and two tank water levels (0.50 and 0.65 m) on the growth performance of juvenile pikeperch of different mean initial body weights in experiment I, II, III respectively (1.1 ± 0.1 g, 5.1 ± 0.2 g, 16.6 ± 0.5 g) at different ages (67, 102, and 137 days post hatch). Two-factor analysis of variance showed that the growth of pikeperch was positively correlated with feed pellet size in experiment I, both feed pellet size and water level in experiment II, and water level in experiment III. The feed pellet sizes of 0.9–1.6 and 1.3–2.0 mm at body weights of 1.1 g and 5.1 g, respectively, are recommended to promote more efficient pikeperch growth rates. In the case of pikeperch with a body weight of 16.6 g, the feed pellet size was less important than the tank water level.

“…In a wide range of teleost species, including flatfishes, light intensity has been seen to influence juvenile growth in association with several other physiological parameters, such as feed intake, survival rate, immune response or dietary nutrient composition, according to species preferences (Kozłowski et al, 2010;Wang et al, 2013;Tian et al, 2015;Bögner et al, 2018). In all cases, better growth was observed at lower light intensities, sometimes associated with differences in stress markers.…”

Optimizing rearing and welfare in Senegalese sole (Solea senegalesensis) broodstock: Effect of ambient light intensity and handling time on stress response

Broodstock rearing conditions and handling procedures should be optimized in aquaculture species in order to benefit fish welfare and guarantee optimal conditions for spawning. In teleosts, basal cortisol levels display daily rhythms, oscillating along the 24 h of the day. In this sense, handling fish at different moments of the day may lead to different stress responses. The present study aimed at investigating the optimal rearing conditions for Senegalese sole broodstock, considering ambient light intensity and handling time. The optimal light intensity (50, 100 or 200 lx) was investigated by measuring fish cortisol levels and monitoring locomotor activity rhythms under each intensity tested. Results showed a significant increase in cortisol levels of fish exposed to 200 lx, when compared to values obtained under 100 lx, accompanied by changes in locomotor activity rhythms in both tanks under study. These results suggested that 200 lx may be too high as light intensity for this species, whereas 100 lx seems to be more adequate. Also, daily rhythms of stress response were investigated in breeders from different origins (Wild and first generation, G1). Basal cortisol levels and cortisol stress response after an acute stressor (air exposure) were monitored at two distinct moments of the day (Mid-Light and Mid-Dark). Basal levels were higher during the day in the wild group, while G1 fish seemed to have lost the daily fluctuations in basal cortisol plasma levels, as well as their daily rhythms of locomotor activity. Both groups showed lower stress responses during night-time, an indication that this is an adequate period of the day to handle this species. Senegalese sole breeders born in captivity presented more pronounced stress responses when compared to wild fish, reflecting their different life history in terms of stress challenges.

“…Polish researchers (Kozłowski et al, 2010) conducted two experiments on growing Sander lucioperca in recirculating aquaculture systems under different light conditions. In group 1, the juveniles had an initial mass of 6.1 g, and in the group 2, it was 42.2 g. It turned out that in both cases, the fish grew better in lower light 45.1 and 1.2 lx, respectively.…”

Effect of illumination on fish and amphibian: development, growth, physiological and biochemical processes

Being one of the main environmental factors, the light factor influences many aspects of animal life. Photoperiod, light intensity (illumination) and wavelength are the primary periodic factors. There is a review that discusses the role of illumination on various life processes of aquatic anamnia vertebrates (fish and amphibians). The effect of light on the development, growth, respiration, consumption and efficiency of food conversion, hormone release, reproduction and behaviour of fish and amphibians has been studied. Illumination influences differently a significant number of physiological and biochemical processes and reactions of anamnia vertebrates at various development stages. The obtained results show that the nature of exposure to light is species-specific and corresponds to the ecological niche of species. Illumination influences both positively and negatively the development, growth and other physiological processes of fish and amphibians. Illumination plays a special role during the first feeding of fish in the environment and aquaculture. There are positive and negative behavioural responses of fish to light. However, it is not always possible to distinguish fish species with only a negative or only a positive reaction to light. The quality of the reaction can be influenced by the stage of development of eggs or larvae, age characteristics, feeding status, season, time, the physiological state of fish, morbidity, etc. A promising area of research is the study of the influence of light on the hormonal status of the body and reproduction of fish. Also, the light pollution and its influence on the physiology of anamnia vertebrates are important.
