“…Vågsholm and Djupvik (1999) found that body deformities developed in Atlantic salmon (Salmo salar L.) more often in fast-growing fish than in slower-growing fish. A similar phenomenon was observed in juvenile tench (Rennert et al 2003, Kamler et al 2006). High growth rates require a disproportionate investment in P-rich biosynthetic cellular structures (Woods et al 2003).…”

“…Recently, the tendency of intensive aquaculture to produce fish of low biological quality, including those with body deformities, has become a problem of major importance (Witten et al 2009, Boglione et al 2013a, 2013b. In tench, an increasingly important aquaculture species, this problem is very common (Rennert et al 2003, Kamler et al 2006, Celada et al 2009, García et al 2010, González-Rodríguez et al 2014.…”

Kamiński R., Sikorska J., Polak-Juszczak L., Wolnicki J. 2017. Effects of temperature on body chemical composition and incidence of deformities in juvenile tench, Tinca tinca (Actinopterygii: Cypriniformes: Cyprinidae), fed a commercial dry diet and/or natural food. Acta Ichthyol. Piscat. 47 (1): 63-71.Background. Water temperature is a major factor regulating fish metabolism. It can influence body chemical composition and the incidence of body deformities. The latter often develop in farmed fish and this issue is currently emerging as a serious problem for aquaculture. Determining the effects of water temperature on body chemical composition and fish body deformities is an important subject for research in fish biology and nutrition, and aquaculture. The presently reported study was conducted using juvenile tench, Tinca tinca (Linnaeus, 1758), an important aquaculture species in Europe. Two hypotheses were tested: 1) temperature can significantly influence body chemical composition and the incidence of body deformities in fish; 2) the effects of temperature on fish depend on their diet. Material and methods. Fish, with an initial total length of 28.4 ± 2.7 mm and body weight of 0.24 ± 0.07 g, were reared at 20, 23, and 26°C and fed dry feed Aller Futura (Aller Aqua, Denmark) only, or a combination of this feed and natural food (frozen larvae of Chironomidae) in a 3 ÷ 2 ratio of dry matter, or the natural food alone. The duration of the experiment and the daily food rations were adjusted to the experimental temperatures based on a correction factor, q, of 1.000, 0.779, or 0.609, respectively. The experiment duration was 92, 72, or 56 days for the respective temperatures.Results. Body deformities occurred in all groups of fish fed solely or partially with the dry diet (21.5%-89.5%). The incidence of deformities was directly proportional to the temperature and the content of dry feed in the diet reaching the maximum in fish fed exclusively the dry diet at 26°C. Water temperature and fish diet influenced body chemical parameters (moisture, protein, lipid, ash, Ca, P, Mg, Ca ÷ P, Mg ÷ P), but water temperature did not have a significant effect on whole-body P content. Conclusions. Water temperature proved to significantly influence fish chemical body composition and the incidence of body deformities in fish fed dry diet. The major factor that caused fish P deficiency, and resulted in low body ash content and body deformities, was insufficient bioavailability of P in the dry diet. Water temperature appeared to only modify P deficiency symptoms in fish. Keywords: fish, food utilization, growth, nutrition, phosphorus INTRODUCTIONWater temperature is a major factor regulating fish metabolic rates, energy expenditure, food intake, and nutritional efficiency. Metabolic rate increases exponentially with temperature, and, at any given temperature, the difference between the energy gained by fish via food intake and the energy consumption by metabolism determines the resources available for growth (Brett and Groves 1979).

“…Tench (Tinca tinca (L.)), is one such species, and although it has been cultured in polyculture with carp (Cyprinus carpio L.) for decades (e.g., Steffens 1995), interest in its culture in recirculating aquaculture systems (RAS) has been on the rise in recent years (Quirós et al 2003, Kamler et al 2006, Wang et al 2006, Zakêoe et al 2006). This species does not assimilate formulated feed very effectively, which can even result in significant losses during culture in RAS (Quirós et al 2003, Rennert et al 2003.…”

Abstract. The aim of the study was to identify the impact of feeding juvenile tench commercial feed supplemented with fish oil, linseed oil, arachide oil, and rapeseed oil on the hematology, cytology, and histology indexes of the liver. The fish were reared in a recirculating system and fed feed containing 470 g protein kg -1 feed and 120 g fat kg -1 feed (1000 g of base feed containing 70 g fat kg -1 feed was supplemented with 50 g of additional fat, i.e., fish oil (FO) or vegetable oilslinseed oil (LO), arachide oil (AO), or rapeseed oil (RO)). Statistically significant inter-group differences were noted for hematocrit (Ht), hemoglobin (Hb), red blood cell (RBC) counts, and other red blood cell indexes, including mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) (P < 0.05). The lowest Ht and Hb values were noted in fish fed feed supplemented with fish oil (group FO), while the highest was noted in the tench from group AO. These differences were mainly caused by the occurrence of smaller erythrocytes in the peripheral blood of the fish from the FO group. No pathological changes were observed in the blood cells, which was in contrast to the parenchymal cells of the liver. Congestion, lipid vacuolization in hepatocytes, regressive changes in cytoplasm density, nuclear chromatin, and nucleus disintegration were observed in all fish. These changes were more pronounced in groups LO and AO. The fish from these groups were characterized by smaller hepatocytes and significantly higher nucleocytoplasmic ratios (P < 0.05).

“…The tench, Tinca tinca (Linnaeus, 1758), a freshwater fish belonging to the family Cyprinidae, has a great potential for aquaculture (Steffens 1995;Kamler et al 2006;Wang et al 2006;Wolnicki et al 2006). Originally occurring in the waters of Europe and Siberia, today tench occurs in the inland waters of all the continents (Skrzypczak and Mamcarz 2006).…”

“…However, feeding tench on commercial dry diets as the only food has been shown to reduce their growth exceptionally (Quirós and Alvariño 1998;Wolnicki and Myszkowski 1998;Quirós et al 2003) and increase the incidence of external body deformities (Rennert et al 2003;Wolnicki et al 2006;Kamler et al 2006), probably a response to unsuitable food. According to Quirós and Alvariño (1998) and Quirós et al (2003), survival and growth of tench can be improved by adding a supplement of live feed (Daphnia sp.…”

A 120-day experiment was performed with 4-month-old juvenile tench [initial mean weight: 0.31 g; total length (TL): 32 mm] to evaluate live Artemia nauplii as supplement to a dry diet for salmonids. All groups received the dry diet. Five treatments, differing in the amount of supplemented Artemia, were tested: without supplement, 450, 900, and 1,800 nauplii g -1 initial fish biomass, and nauplii in excess. Groups that received Artemia supplement had significantly higher survival (between 89.4 and 98.7%) compared to those that received dry diet alone (49.2%), while among them there was no significant difference. Juvenile tench fed the dry diet supplemented with Artemia in excess had a specific growth rate (1.98), weight (3.40 g), and TL (63.90 mm) significantly higher than those in the rest of the treatments. The latter three features were not significantly different under limited co-feeding (450, 900, and 1,800 nauplii g -1 biomass) averaging 1.26 specific growth rate, 1.40 g weight, and 48.50 mm TL. Tench fed the dry diet alone grew significantly less than the rest. Thus, the drawbacks of feeding juvenile tench with dry foods originally formulated for other fish species can be overcome by providing a supplement of Artemia nauplii.
