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.

Present work was done from Indus River, Sukkur, Sindh, Pakistan to evaluate the present stock of Cirrhinus reba Suhni (Reba carp) for first time. Since the assessment of stocks deliver the important knowledge of stocks of commercially important fish species to the fisheries managers to make better strategic plans for sustainable exploitation. Data based on length-frequency was obtained from October 2015 to March 2016, a total of 463 pairs of length-weight were measured. Minimum length was measured to 13cm, maximum length was 29cm and the average length of 17cm was measured with minimum weight of 15g, maximum weight of224g and67g was the average weight. Obtained results of length-weight relationship were R2 = 0.817, a = 0.037 and b = 2.557. Growth parameters were computed as L∞= 29.40 cm and= 0.240 year-1using ELEFAN method in FISAT computer package. Growth performance index (∅′) was calculated as ∅′ = 2.317 year-1 Total mortality Z, natural mortality M and fishing mortality F was estimated as= 0.630 year-1, M= 0.617 year-1 and F=0.012 year-1 respectively. Using (E = F/Z) the exploitation ratio was obtained as E=0.019 year-1 Current fishing mortality rate of 0.012 was smaller than the target biological reference points (Fopt) of M (0.617). While MSY was recorded as; 8.144 tonsyear-1 which showed the higher results than 0.031 tons year-1ofcurrent catch. This study concluded that the C. reba confronting poor health though the stocks found not to be overexploited in the region. Bangladesh J. Zool. 48(1): 81-91, 2020

Different body fat reserves in male and female yellow perch (Perca flavescens) may determine a marked differential mortality during the winter. This was revealed by a study in two Laurentian lakes of the Province of Quebec harboring stunted yellow perch with a marked predominance of males. The proportion of females in each year-class is markedly smaller, thus suggesting a higher mortality among immature and mature females than among males.In an attempt to explain the differential mortality, the seasonal variation of body fat content in males and females was measured; also the fat level at time of death caused by starvation under laboratory conditions was determined. The results showed that in the females the body fat content falls to a critical level of about 2% at least 4 mo before spawning, whereas the males maintain a fat level of almost 5% throughout winter.

LANGUAGE NOTE | Document text in English; abstract also in Chinese.The purpose of the study was to determine the maximal oxygen consumption (V02 max) and the body fat content in Malaysian national junior netball players and the impact of an eight-week aerobic and strength-training programme on these two variables. A total of 21 netball players (mean age of 16.12±1.55 years old) from Bukit Jalil Sports School were the subjects used. The 12-minute Run was used to determine the V02 max while the body composition was calculated using the skinfold method. Pre-test and post-test results showed significant improvement in the V02 max and body fat content among the netball players. The Z value for the V02 max test was -3.25 (p

LANGUAGE NOTE | Document text in English; abstract also in Chinese. This study sought to document the physical characteristics of top Malaysian netball players by their playing skill. The variables measured were age, height, body mass, body fat and somototype. Thirty-two national players (mean age 18.19 ± 3.86 years) were assessed, divided into three groups by their playing skill (senior/elite, junior and reserve). The body fat content was determined by the skinfold method and their somatotype using the Heath Carter Somatotyping method. There were no significant differences in the physical characteristics between the players by playing skill. The players were predominantly ecto-endomorphic with a mean somatotype of 6.12±1.42 - 2.38±1.05 - 2.71±1.38. Their height and body mass were 170.80±4.61 cm and 64.44±7.46 kg, respectively. Female national Australian and English netball players had a body fat of 28.90±3.50% (Wither & Roberts, 1981) and 24.50±3.90% (Bale & Hunt, 1986) respectively, while the Malaysian players in this study 24.50 ± 5.13%. 本文旨在探討馬來西亞女子投球選手的身體特徵與技術，並與同類研究進行比較及分析。

Patients with inflammatory bowel disease (IBD) suffer from body weight loss, malnutrition, and several other metabolic alterations affecting their quality of life. The aim of this study was to investigate the metabolic changes that may occur during acute and chronic colonic inflammation induced by dextran sulfate sodium (DSS) in mice. Clinical symptoms and inflammatory markers revealed the presence of an ongoing inflammatory response in the DSS-treated mice. Mice with acute inflammation had decreased body weight, respiratory exchange ratios (RER), food intake, and body fat content. Mice with chronic inflammation had decreased nutrient uptake, body fat content, locomotor activity, metabolic rates, and bone mineral density. Despite this, the body weight, food and water intake, lean mass, and RER of these mice returned to values similar to those in healthy controls. Thus, murine experimental colitis is associated with significant metabolic alterations similar to IBD patients. Our data show that the metabolic responses during acute and chronic inflammation are different, although the metabolic rate is reduced in both phases. These observations suggest compensatory metabolic alterations in chronic colitis resulting in a healthy appearance despite gross colon pathology.

1. The principal change in the composition of adult fowls during fattening is an increase in the fat content of the body, the protein increase being subordinate in amount.2. Within the limits studied, the efficiency of conversion of food energy to carcase energy is not affected by variation in the protein content of the ration.3. A food mixture consisting of 5% dried skim milk of 95% Sussex ground oats proved as efficient for fattening fowls as a food mixture consisting of 20% dried skim milk, and 80% Sussex ground oats.4. The food mixtures used gave satisfactory results in fattening when used in pellet form in a dry state.

1. Height, weight, skinfold thicknesses and mid-arm circumference were measured in 540 males and 117 females aged 20-24 years who took part in the 1st African University Games, held at the University of Ghana, Legon. Body fat content, Quetelet's index (weight ÷ height × 100; Khosla & Lowe (1967)) and mid-arm muscle circumference were derived from the measurements taken.2. The physique or body-build of the subjects as assessed by Quetelet's index showed that both male and female subjects from the various countries were of medium body-build. The body fat content for males was between 10 and 12% with the exception of the Egyptians (12.8%) while that of females was between 23-24%.3. Body measurements of the subjects compared favourably with that of international standards (WHO, 1966) with the exception of the triceps skinfold thickness which was only approximately 60% of the standard value.4. The low values for triceps skinfold thickness are probably due to differences in the distribution of subcutaneous fat at different sites in the body as found between caucasian and non-caucasian population groups. The results are discussed in relation to the findings of other workers on ethnic differences in skinfold thickness.
