Abstract The aim of the study was to determine the impact the commercial supplement S.presso (INVE Aquaculture, Belgium), a source of polyunsaturated fatty acids to enrich the proximate composition of brine shrimp (Artemia sp.), had on their growth and mortality. Four different enrichment protocols were investigated: the supplement was given in one or two doses at various time intervals. The results indicate that while S.presso increased nauplius mortality slightly, administering the appropriate dose reduced losses to a very low level (from 12.5% with a single dose to 8.6% with the recommended dose divided into to equal parts). Additionally, it was confirmed that the supplement S.presso increased brine shrimp growth slightly in comparison to that of the control group, but the differences were statistically insignificant. The results permit concluding that S.presso is suitable for use as a source of polyunsaturated fatty acids for brine shrimp enrichment with the intent of using them as fish food.

Abstract A survey on the occurrence and epidemiology of the encysted progenetic metacercariae of Euclinostomum heterostomum infection in Channa punctata in the Aligarh region of North India revealed a mean prevalence, intensity, and abundance of 18.61, 1.52, and 0.38%, respectively, during the period from April 2011 to March 2012. Liver, kidney, peritoneum, muscle, and ovary were found to be infected with this parasite, and the later three are reported for the first time in this fish species. The histopathology of the infected tissues indicated the following at the host-parasite interface: tissue damage, infiltration of immune cells into the cyst wall, chronic inflammatory responses, and granulomatous lesions. The infected liver showed degeneration of hepatocytes, cytoplasmic vacuolation, nuclear alterations, mallory body formation, fibrosis, and necrosis. The pathology of the infected kidney included distortion and dilation of renal tubules, vacuolar degeneration, hypertrophy and hyperplasia of tubular epithelial cells, occlusion of tubules, fibrosis, hemorrhage, and congestion of glomeruli. The infected muscle demonstrated comparatively fewer pathological changes confined only to the circumference of the cyst wall. The ovary displayed the least changes. The conclusions drawn from the study are that the large metacercarial cysts formed by E. heterostomum in the vital organs of the economically important fish C. punctata could result in the impairment of fish physiology and health, thereby affecting their productivity and quality for human consumption.

Abstract The reproduction biology of Caspian vimba, Vimba vimba (L.), was investigated on the southwestern coast of the Caspian Sea using 712 fish specimens collected at three fisheries catch stations located in Talesh, Anzali, and Kiashahr over a two-year period from April 2012 through June 2013. Seasonal changes in the gonadosomatic index, gonad histological status, size frequency distribution of oocytes, and the fecundity of the species were studied. The peaks of the gonadosomatic index (GSI) were observed both in females and males in June 2012 and May 2013 indicating the variable peak spawning time of this species. Histological examinations and oocyte frequency distribution patterns showed synchronous oocyte development in the Caspian vimba. Absolute fecundity ranged from 5873 to 35421 eggs. The size at first maturity for females was 120 mm FL. We concluded that the Caspian vimba is a total spawner with variable spawning dependent on environmental factors.
2012年4月至2013年6月，在里海西南海岸的Talesh、Anzali和Kiashahr三个渔场采集了712种鱼类标本，对里海vimba (L.)的繁殖生物学进行了研究。研究了该物种的性腺指数、性腺组织学状态、卵母细胞大小频率分布和繁殖力的季节变化。2012年6月和2013年5月雌、雄鱼的性腺指数(gonadosomatic index, GSI)均出现峰值，表明该物种的产卵高峰时间不稳定。组织学检查和卵母细胞频率分布模式显示里海琴的卵母细胞发育同步。绝对繁殖力在5873 ~ 35421个卵之间。雌梭鲈初成熟时的大小为120 mm FL。我们认为，海梭鲈是一种完全产卵者，其产卵量受环境因素的影响是可变的。

Abstract Edwardsiella tarda is one of the serious fish pathogens infecting both cultured and wild fish species. This study aimed to assess the phenotypic characterization and pathogenicity of E. tarda isolated from Clarias gariepinus (Burchell) with dropsy and histopathological alterations. The causative agent was identified with Vitek 2, and its pathogenicity was determined by intramuscular injection. The challenged catfish exhibited vertical hanging, frothing, excess mucus production, listing, swollen abdomen, anorexia, fin and tail rot, and reddish operculum. The LD50 of E. tarda PBB and PBP strains was found to be 8.52 × 106 and 1.68 × 107 cells fish-1, respectively. Histopathological observations on catfish infected naturally revealed lymphocyte infiltration in muscle and focal necrosis, hyperplasia, edema, and swelling of the gill lamellar epithelium. The kidney of diseased fish exhibited ischemic type tubulopathy, necrosis of nephritic tubules, hyperplastic hematopoietic tissue, rupture of the tubular basement membrane, hydropic dystrophy of nephritic cells, neutrophil infiltration, fibrinoid necrosis of nephretic tubules, hemosiderin deposition, and edema. The liver sections revealed lymphocyte infiltration, dilation of hepatic sinusoids, expansion of space between hepatic sinusoids, and focal necrosis. The inflammatory responses observed in kidney and liver in the present study were presumably suppuration and were attributed to the potential virulence factors of E. tarda.

Abstract This paper discusses the problem of the occurrence of non-native fish species in a strongly transformed aquatic ecosystem. The changes in this ecosystem are caused by warm water discharges from two electric power plants. Twelve non-native fish species are confirmed to occur in the system of five heated lakes located in central Poland. In total, 30% of the total number of non-native species confirmed in Polish inland waters were noted. Aquaculture and fisheries are the primary sources of non-native species in these lakes. Among the species identified, most reached the lakes or canals by escaping from farming facilities or through commercial stocking. Four species have established stable populations. Pseudorasbora parva (Temminck & Schlegel), Carassius gibelio (Bloch), and Carassius auratus (L.) are invasive species that occur abundantly in all the lakes, while Cyprinus carpio L. reproduces irregularly and only in the most heated lakes. The remaining species do not reproduce in the heated lakes system, or anywhere else in Poland; still, the threat these species pose must not be underestimated.

Abstract In the present study, the effects of vitamins E, B2 and combinations of them on hematological parameters of common carp, Cyprinus carpio L., were investigated during a 56-day experiment. The various dietary levels of vitamins E, B2 and their combination were used as experimental treatments, as follows: T1: vitamin E (80 mg), T2: vitamin E (160 mg kg diet-1), T3: vitamin E (240 mg kg diet-1), T4: vitamin B2 (7 mg kg diet-1), T5: vitamin B2 (15 mg kg diet-1), T6: vitamin B2 (20 mg kg diet-1), T7: vitamin E (80 mg kg diet-1) + vitamin B2 (7 mg kg diet-1), T8: vitamin E (160 mg kg diet-1) + vitamin B2 (15 mg kg diet-1), T9: vitamin E (240 mg kg diet-1) + vitamin B2 (20 mg kg diet-1). One group not given vitamin supplements was the control. The values of red blood cells (RBC), hemoglobin (Hb), and hematocrit (Hct) were higher in T7 than in the other experimental treatments. The values of white blood cells (WBC) were higher in T2 than in the other treatments. The concentration of immunoglobulin (IgM) was also lower in T10 than in the other experimental treatments. The highest values of mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) were observed in T2. No significant differences were noted among experimental groups in the values of mean corpuscular hemoglobin concentration (MCHC). This study showed that vitamin E and B2 supplements alter the hematological parameters of common carp.

Abstract After meat and dairy products, fish meat is one of the greatest sources of animal protein, but it is also probably the most susceptible to oxidation. The study material consisted of carp, Cyprinus carpio L., meat. The left and right sides of the fillet were divided into three parts, the head, abdomen, and tail. On the first day of the study, the anisidine value ranged from 0.21-1.70, and did not differ significantly among the body parts. Peroxide values fluctuated frequently during the study. Lipid oxidation depended on the part of the fish the meat came from and the structure of the meat, either fillets or ground meat.

Abstract Factor and multiple regression analysis were used to extract the morphometric variables that contributed to feeding success in three small freshwater fishes. Of the first two factors, factor 1, showed high loading of gut weight (GW), length of the upper (UJ), and lower jaws (LJ) in mola, Amblypharyngodon mola (Hamilton), and GW and vertical mouth opening (VMO) in punti, Puntius ticto (Hamilton). In darikana, Esomus danricus (Hamilton), GW, horizontal mouth opening (HMO), and VMO were highly loaded on factor 2. Gut length (GL) was closely associated withGWof all three species. Subsequently, variables with high loading on factors 1 or 2 were subjected to multiple regression analysis to observe their effect on feeding success, consideringGWas the dependent variable and the extracted variables as the independent variable. In A. mola, HMO and GL influenced GW, whereas in P. ticto, only GL determined GW in the fish. In E. danricus, GL, VMO, and HMO exerted a low effect on GW. Exceptionally, the present study suggested that feeding success in small fishes is largely determined by UJ, LJ, and GL or mouth openings.

Abstract Alternative proteins from vegetal sources are being studied, because of the high costs and limited resources of fish meal. The aim of this study was to determine the possibility of including cold-pressed rape cake (CPRC) as a partial protein substitute in diets for common carp, Cyprinus carpio L. Common carp fry were stocked into experimental ponds at a density of 30 fish per pond. The effects on growth, feeding efficiency, and fish body composition were studied for four amounts of CPRC (0, 70, 130, 200 g × kg-1). Statistically significant higher final weights (528-530 g) were obtained with fish fed diets with 130 and 200 g × kg-1 CPRC. The fish growth rate was nearly identical in all variants (SGR of 3.3-3.4 % d-1). Similar results were presented in FCR at 1.3, and in PER at 2.2. Our results suggest that it is possible to include up to 200 g × kg-1 of CPRC in diets for two-year old common carp without significant effects on growth, nutritive efficiency, or the proximate composition of the fish.

Abstract The occurrence of Rutilus virgo (Heckel) has been confirmed in the Transcarpathian region of Ukraine, where it was caught in the lower stretches of the Latorica and Borzhava rivers. The comparison of selected morphometric features of R. rutilus and R. virgo showed that 26 of 40 of them were significantly different and the largest differences were observed for features such as head length, maximum body depth, pectoral fin length, pectoral fin thickness, pelvic fin length, head depth at eye level, maximum head depth, and preorbital length. The comparison of R. virgo of two size groups showed a number of changes in fish body proportions during fish growth, where 29 of 38 features were different. Length-weight relationship for mixed sexes was a = 0.0157, b = 3.088. The fecundity of R. virgo depended on age and varied from 6775 eggs (age 4+) to 51535 eggs (age 8+). R. virgo inhabiting the rivers of the Transcarpathian region is characterized by relatively rapid growth rate, and the results are within growth rate limits reported in the literature.
在乌克兰的外喀尔巴阡地区，在拉托里察河和博尔扎瓦河的下游被捕获，已证实发生了Rutilus室女(Heckel)。在选取的40个形态特征中，有26个差异显著，其中头长、最大体深、胸鳍长、胸鳍厚度、腹鳍长、眼平头深、最大头深、眶前长度等特征差异最大。两个尺寸组的比较表明，鱼体比例在鱼的生长过程中发生了一些变化，38个特征中有29个特征不同。混合性别的长权关系为a = 0.0157, b = 3.088。雌瓢虫的产卵量与年龄有关，从6775个(4岁以上)到51535个(8岁以上)不等。栖息在喀尔巴阡山脉外河流的室性赤霉生长速度较快，其结果在文献报道的生长速度限制范围内。
