The anguillid eel is a catadromous eel capable of inhabiting freshwater growth habitat and seawater spawning habitat throughout their life cycle. At the juvenile to mature stage, they inhabit freshwater then migrate to marine water to spawn. Changes in salinity, which is one of the stressful environmental factors for the eel, affect their physiological condition by increasing the leukocytes number. This increase is an adaptation method to improve their immune system as a response to salinity change. This study intended to evaluate the leukocyte differential of anguillid eel (Anguilla bicolor McClelland) exposed to various salinities. This research applied a Completely Randomized Design. The treatment was three levels of saline media including 4 ppt, 15 ppt, and 30 ppt with five replicates. The independent variable was the different salinity, and the dependent variable was the leukocyte differential. The parameters measured consisted of the different percentage of neutrophils, lymphocytes, monocytes, and eosinophils in which the measurements administered after two months of the eel exposure. We analyzed the data with ANOVA at the confidence level of 95%. The results showed that exposure of salinity significantly affected the percentage of leukocyte differential (P < 0.05). The increase in salinity decreased the neutrophils and monocytes, but increased the lymphocytes, and showed no effect on eosinophils.

Superoxide Dismutase (SOD) is an antioxidant enzyme which reduce anion superoxide radicals as well as known caused of diabetes. There are many natural additive was believed having capacity to repaired an antioxidant celluler status. Cardamom’s stem were reported containing flavonoid and vitamin C which have been proven as in vitro antioxidant. There was no data showing its in vivo potency. This study aims to knoe the SOD activity of diabetes rats which were given cardamom stem extract (CSE) and glibenclamide. The research carried out with the use of experimentally Randomized Design Complete (RAL) by administering treatment on diabetes rat without CSE and glibenclamide as a control, consist of 100 mg/kg bodymass CSE and 2 mg/kg bodymass glibenclamide. The experiment consists of 3 treatments with 7 repetitions, blood sampling carried out experiments as much as 3 times with intervals of 7 days once. The data was analyzed using a variety of analysis (ANOVA). The result showed that the SOD activity increased from 4261 Unit/mg protein to 6604,668 Unit/mg protein (P<0.01) in diabetes rats treatment by CSE for 14 days.

Probiotics MEP+ can increase fowl weight and weft efficiency, therefore it is important to know probiotics MEP+ effect at different dosage toward reproduction aspect. This research aimed to examine duck reproduction organ size suplemented with probiotics MEP+ with different dosage within 30 days. This research used Completely Randomized Design (CRD) with 4 treatments with different dosages within 30 days which was without probiotic’s application or control (K), 0,75 ml/kg wefts (P1) dose, 1,5 ml/kg wefts (P2) dose, a n d 3 ml/kg wefts (P3) dose. Each treatment repeated 8 times. Total 40 ducks raised in floor dry cage system. At 31st day of treatment duck reproduction system organ was measured. Whole results show increase average data (±SD) for weight of both right and left testis, and liver weight with highly probiotics dosage it, however the analysis result statistic not significant (P>0,05) except weight of right left testis with duck weight or gonadosomatic indeks (GSI) were very significant (P<0,01) among all treatment at different dosages was compared control. The results is confirmed that probiotic's MEP+ treatment with different dosages within 30 days gave no effect towards duck reproduction system organ size except to gonadosomatic indeks (GSI) male duck.

Eel (Anguilla bicolor) is a catradomous fish, in the growth phase of life in freshwater and upon reaching adult will migrate to ocean waters to reproduce. Eel during the migration will use energy from body reserves to osmoregulation. Increased salinity will affect the osmotic pressure of the body of the fish so that the fish do active transport which requires energy. Energy that used for osmoregulation approximately 20–50% of the total energy from carbohydrates, fats and proteins. Carbohydrates are the first source of energy that is used and then will be replaced by fat and protein as energy after carbohydrate depleted. Thus the energy utilization during osmoregulation will affect the changes in the composition of protein and fat content of the body. Fat content will affect the value of lipostatic fish is one of the growth parameters. The purpose of this study was to evaluate changes in the levels of protein and lipostatic eel (Anguilla bicolor) is maintained in a range of salinity. This research method is experimental research design with CRD, treatment in the form of maintenance medium salinity; 4 ppt (control), 15 ppt, and 30 ppt. Each treatment was repeated 5 times. Test fish used were obtained from the Village Pesanggrahan Cilacap with range size between an average weight of 395–920 g and an average length of 59–81 cm. The variables measured were the levels of protein and lipostatic eel. Protein content measurement was conducted using kjeldahl and the fat content by soxhlet. Research results showed that the eels were exposed to salinity 4 ppt, 15 ppt and 30 ppt no effect on protein content and body lipostatic eel. It can be concluded that the eel is able to adapt well in the range between 4 ppt salinity to 30 ppt.
