Effect of hydrogen sulphide on liver somatic index and Fulton's condition factor in Mystus nemurus

This study aimed to provide information about the population structure and somatic index of Hypostomus cf. ancistroides collected from the Bonito river, located in the Ivaí river basin. The length-weight relationship was isometric for both the sexes. The length structure analysis showed that the larger individuals (from 18.1cm to 27.0cm in length) predominated, and the lowest abundances occurred at the size extremes (9.1-12cm and 27.1-30.0cm). The reproduction period occured between October and January for the females and between November and January for the males. The liver somatic index cannot be used as an indicator of the reproduction period in either of the sexes, due to no correlation between the liver somatic index and the gonad somatic index. The gonad weight exerted no influence on the monthly mean condition factor and the correlation between the condition factor and gonad somatic index was high. The condition factor could be an indicator of the reproduction period of this species.

The reproductive biology of Heterotis niloticus has been studied from monthly samples taken from artisanal fishing on the Agneby river during the period june 2013 to May 2015. The whole sample consisted of 498 specimens of which 269 females and 229 males were examined. Sex-ratio observed was in favour of females (1: 1.17; X2 = 3.21; p > 0.05). The monthly evolution of the gonado-somatic index (GSI), the liver-somatic index (LSI), the condition factor (K) and maturation stages suggests that this fish has two periods of reproduction. The two periods were respectively from june to august and from november to december. The standard length at first sexual maturity was 490.6 mm for females and 436.3 mm for males. The absolute fecundity was ranged from 5424 to 25591 oocytes in females of 595 mm to 780 mm standard length. The relative fecundity was 3752± 1491 oocytes/kg of female.

Abstract Objectives Ethanol consumption is associated with a spectrum of diseases in the liver ranging from steatosis, alcoholic hepatitis to cirrhosis and hepatocellular carcinoma. We established an alcoholic liver disease model in mice to investigate the protective effects of the phytoextract blend (PB) including schisandra, grape seed and tart cherry. Methods A total of 100 mice were randomly divided into 5 groups. The groups were: a) control group, b) ethanol group and c) three experimental groups. Animals in the control and ethanol groups were orally gavaged with distilled water, while the other groups were given varying concentrations of PB for 30 days. The ethanol group and the treatment groups were then given ethanol for 15 days. The liver/somatic index, levels of ALT, AST, TBIL and TG in serum, and the expression of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were measured. The liver tissues were stained with hematoxylineosin (H&E) for evaluation of histopathological changes. Results The liver/somatic index was increased in the ethanol group while it was decreased nearly to the normal value in treated groups. ALT increased significantly in ethanol group. PB reduced serum ALT concentrations in a dose-dependent manner. Ethanol elevated AST in the ethanol group. Although PB low dose group showed increased AST levels, AST was decreased by medium and high doses of PB compared with the ethanol group. Ethanol slightly though not significantly downregulated TBIL level in the ethanol group, while low and medium doses of PB increased TBIL. Ethanol-induced TG upregulation was completely reversed by PB treatment. The expression of hepatic IL-6 and TNF-α mRNA were elevated after ethanol consumption, whereas these inflammatory cytokines were reduced after treatment. Ethanol induced necrosis and substantial small fat droplets in the liver section. However, livers of mice in all treated groups showed noticeable recovery with fewer small fat droplets and hepatocyte necrosis. Conclusions This study showed the PB containing schisandra, grape seed and tart cherry could protect liver by reducing hepatic steatosis and hepatocyte necrosis and alleviating inflammation. The PB used in this study may provide insights into the prevention and treatment of ethanol-induced liver injury. Funding Sources Nu Skin Research Funding. Supporting Tables, Images and/or Graphs

Somatic Index

To provide an integrated perspective on mineral particle effects in salmonids, juvenile rainbow trout (Oncorhynchus mykiss) were exposed to daily mica particle pulses for 8 and 24 days. On day 8, increased immature erythrocyte proportions indicated a previous stress response. This response was absent on day 24, on which condition factor as well as plasma protein and aspartate aminotransferase activity decreased. The latter two related negatively to the hepato-somatic index, suggesting metabolic adaptations. The hepato-somatic index increased on days 8 and 24, while spleen-somatic index increased on day 24. No histopathological damage occurred in gills, liver, spleen, or kidney. However, splenic melano-macrophages increased on both days, and hyaline degenerations of kidney tubular cells were apparent on day 24. Overall, particle pulses affected rainbow trout more via turbidity rather than by physical damage. We conclude that (i) rainbow trout may adapt to sediment pulses as early as 8 days of exposure and (ii) particle pulses over 24 days can cause structural and metabolic changes in rainbow trout, even when gill damage is absent and apical effects on condition are moderate.

A study was conducted to determine the prevalence and effects of two species of blood-feeding copepods on their definitive fish hosts, viz. Haemobaphes cyclopterina parasitizing Arctic cod (Boreogadus saida) and H. intermedius infecting tidepool sculpins (Oligocottus maculosus). Infected and uninfected Arctic cod and tidepool sculpins were captured by SCUBA and dip net in the northwest Atlantic and northeast Pacific, respectively. Biological variables such as condition factor, hepatic somatic index, gonadal somatic index, and haematocrit were compared between the two groups of Arctic cod of both sexes, whereas only condition factor was compared in the two groups of sculpins of both sexes. Prevalence of H. cyclopterina (8%) was considerably lower than that of H. intermedius (46%). This difference is probably associated with the hosts' behaviour, as the Arctic cod is pelagic whereas the tidepool sculpin is restricted to the littoral zone, where infections are probably acquired. Infected Arctic cod of both sexes had significantly lower condition factor, hepatic and gonadal somatic indices, and haematocrit than non-parasitized fish. Only females harboured large numbers of the parasite and showed even more dramatic changes than the corresponding groups. The growth period of H. cyclopterina on Arctic cod from the time of infection to the fully developed egg sac stage is probably about 6 months. In tidepool sculpins, condition factor was significantly lower in infected than in uninfected fish. These results, especially for the Arctic cod, parallel those reported for gadoid fish following infection with haematophagous species of Lernaeocera that impair growth and reproduction.

Worm meal obtained from worms (Eisenia fetida) raised on waste materials was evaluated for Rainbow trout as a replacement for fish meal at dietary concentrations of 250, 500 and 1 000 g replaced per kg. During the study period none of the diets was detrimental to fish health. The dietary concentrations of 250 and 500 g/kg replacement gave higher growth rates than that of the control group (0 g/kg replacement), the former having consumed less food. The biological parameters of food conversion efficiency and protein efficiency ratio, for these replacement levels, also showed values better than the control diet. Liver somatic index and the chemical composition of fish fillets showed no significant differences between diets, except for a significant decrease in lipid content with increasing worm meal inclusion.
