Abstract The purpose of this study was to investigate the sublethal Co toxicity on rainbow trout (Oncorhynchus mykiss). Trout were exposed to Co and selected parameters were evaluated at intervals of 1, 15 and 30 days. Fish exposed to higher levels of Co grew slower than fish exposed to lower levels of Co. Weight gain, specific growth rate (SGR) decreased linearly with the increase of cobalt in the water. The body condition factor (CF) of fish reared in water with low cobalt concentration decreased substantially but this decrease was not significant for fish exposed to higher cobalt concentration. The values of the feed conversion ratio (FCR) increased in fish exposed to higher levels of Co. Co significantly changed the activity of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) and decreased at day 30, and in both cases this decrease was more remarkable at day 15 so that the level of AST and ALT reached the control value at day 30. The alkaline phosphatase (ALP) level also showed a remarkable 15-day decline. There was a significant increase in glucose (G) concentration in both Co-exposed groups on day 15. However, serum cholesterol (Chl) was significantly reduced on day 15 and increased on day 30; there were no significant differences in both exposed Co-groups. The triglyceride (TG) level also decreased substantially. There was no regular pattern of total protein (TP) in the serum, so that no significant differences were found in the level of TP between low and high-exposed fish. In summary, this study suggests that exposure of essential trace elements such as cobalt may change growth and biochemical parameters, and that measurement of these parameters may be used in toxicological studies to determine the general health status of fish.

Abstract Cooperative-based growth model for agricultural enterprises is gradually gaining popularity in application. This study examined the effect of cooperative financial intervention on the growth of catfish aquaculture value chain in Nigeria. Primary data collected, with well-structured questionnaire from 120 participants in aquaculture value chain, were analyzed with descriptive statistical tools, cost and return function and 4-point likert-type scale. The result shows that 32.3% and 27.3% of processors and input suppliers accessed N320,000 and N270,000, respectively. Only 18.2% of producers accessed N180,000. The result indicates that there are more catfish producers than any other operators in the value chain. There is interdependence between catfish producers and input suppliers, processors and marketers in the value chain. Furthermore, catfish processors and inputs suppliers accessed more cooperative loan because their activities were capital intensive. The relatively high amount of cooperative fund accessed by these groups translated high growth rate of 55% and 53%, respectively. The major constraints to the growth of catfish value chain were inadequate credit access and high expenditure on inputs. Operators in the catfish aquaculture value chain should be encouraged to attend workshops on management techniques to improve the efficiency of their businesses.

Abstract Efficacy of ethanol and methanol extracts of medicinal herb Withania somnifera roots was evaluated in Nile tilapia Oreochromis niloticus on immunostimulation and growth. Withania roots were extracted with water, ethanol, methanol, methylene chloride, hexane, successive methanol. Phenol, flavonoid content and antiradical activity of all the extracts were measured. Ethanol extract showed the highest phenol, flavonoid content and antiradical activity followed by methanol extract. Subsequently, Nile tilapia (n = 126) were fed diets containing different concentrations (0.0, 0.3, 0.5 and 0.7 g kg−1 feed) of ethanol and methanol extracts of W. somnifera roots for 30 days (3 replicates). Fish fed plant extract fortified diets showed significantly better (P<0.05) immunological, haematological, biochemical and growth parameters compared to the fish fed control diet. Fish fed diet containing ethanol extract at the concentration of 0.7 g kg−1 feed showed the highest immunological (phagocytotic activity, respiratory burst activity, serum lysozyme, total protein, total immunoglobulin), haematological (total red blood cells, haemoglobin, hematocrit, total white blood cells, lymphocyte), biochemical (reduced glutathione, glutathione reductase activity) and growth (final weight, weight gain, daily weight gain, specific growth rate) parameters. The plant extract might act as potent free radical scavenger in fish tissues and have tissue protecting ability, thus increasing fish health.
摘要采用尼罗罗非鱼为试材，研究了中草药紫薇根乙醇和甲醇提取物对尼罗罗非鱼免疫刺激和生长的影响。用水、乙醇、甲醇、二氯甲烷、己烷、连续甲醇提取薇甘菊根。测定了所有提取物的酚、黄酮含量和抗自由基活性。乙醇提取物的酚、类黄酮含量和抗自由基活性最高，其次是甲醇提取物。随后，尼罗罗非鱼（n=126）被喂食含有不同浓度（0.0、0.3、0.5和0.7 g kg−1饲料）的桑蚕根乙醇和甲醇提取物的日粮30天（3次重复）。与鱼类喂养的对照日粮相比，鱼类喂养的植物提取物强化日粮显示出显著更好的免疫学、血液学、生化和生长参数（P<0.05）。含有浓度为0.7 g kg−1的乙醇提取物的鱼饲料显示出最高的免疫学（吞噬活性、呼吸爆发活性、血清溶菌酶、总蛋白、总免疫球蛋白）、血液学（总红细胞、血红蛋白、红细胞比容、总白细胞、淋巴细胞），生化（还原型谷胱甘肽、谷胱甘肽还原酶活性）和生长（最终体重、体重增加、日体重增加、比生长率）参数。植物提取物可能在鱼类组织中起到强大的自由基清除剂作用，并具有组织保护能力，从而提高鱼类健康。

Abstract The objectives of the present study were to determine the size distribution, growth pattern, feeding habit and stomach fullness index of bullet tuna Auxis rochei in the Makassar Strait, West Sulawesi. The research was conducted for six months between March and August 2017. Sampling collection was carried out using the handline technique. A total of 2160 fish were caught. Their total length ranged from 15.8 to 28.5 cm and weight ranged from 52.3 to 366.5 g. The total length of male fish ranged from 18.5 to 28.5 cm and weight ranged from 77.5 to 366.5 g. The total length of female fish ranged from 15.8 to 27.5 cm and weight ranged from 52.3 to 328.8 g. The growth pattern of bullet tuna for both male and female fish was classified into a positive allometry (b>3); the type of food found in the fish gut consisted of crustacean (12.50% to 25.64%), chepalopods (7.32 to 34.80%) and unidentified (47.69 to 64.51%), respectively. Nonetheless, the predominant food condition was not identified and in the gut there was generally no food present. The stomach fullness index ranged from 1.13% to 7.18%, ¾ (12.11 to 15.74%), ½ (12.27 to 23.14%) and empty (59.26 to 65.74%). The length size distribution of male bullet tuna was larger than the female with a positive allometric growth pattern. However, the growth pattern of male and female bullet tuna statistically showed no difference.

Abstract The aim of this research was to define the participation rates of freshwater anglers in Croatia, their changes over the years and their differences across the counties of Croatia. In spite of a continuous population decline ever since Croatia joined the EU, the number of anglers has slightly increased to around 1%. The counties can be divided into three groups – counties on the Adriatic coast where marine fisheries are dominant, a very urbanized City of Zagreb and the remaining inland counties. In freshwater recreational fisheries in Croatia, the tradition and availability of fishing grounds dominate the participation rate of anglers. However, there are indications of the influence of GDP values so the counties with GDP over 6,500 euros per capita expressed positive relationship to the percentage of anglers (p<0.05). On the other hand, densely populated county of the City of Zagreb confirms that urbanization and much higher GDP result in a much lower percentage of recreational fishermen.

Abstract Wastewaters from a treatment plant discharging into a canal harboring fish may present sources of microbiological hazard for wild fish. Such fish, inhabiting microbiologically polluted bodies of water, can be contaminated by human pathogens and, if used for human consumption, may pose a risk to public health. Hence, in this work the aim was to identify tested strains from tissues of wild fish living in the receiving water bodies, captured from locations up to 12 km from the point of discharge of treated water of town Virovitica in order to assess the bacterial threat of the WWTP on fish and potentially on public health. A rather rich diversity of bacterial genera was isolated from gill tissues and internal organs. The most frequent isolate was Aeromonas hydrophila which has gained public health recognition as an opportunistic pathogen. Vibrio cholerae, an indicator bacterium for aquatic contamination, was retrieved from all investigated tissues. Opportunistic human pathogens as well as some zoonotic agents were also retrieved from fish tissues (Enterobacter amnigenus, Acinetobacter spp., Ochrobactrum anthropi, Pseudomonas aeruginosa, Flavimonas (Pseudomonas) oryzihabitans, Shewanella putrefaciens and others). Public health hazard is particularly pronounced regarding local recreational fishermen who fish out, handle and consume fish from respective waters.
