Tissue Hypertrophy: A Quantitative Adaptational Strategy During Cold Acclimation in Channel Catfish and Green Sunfish (Immunoelectrophoresis, Heart, Liver, Protein Synthesis, Degradation)
… 25 C acclimated catfish as shown by doubling of hepatosomatic index (HSI) and total liver protein. No change occurs in protein concentration or total liver DNA. The same pattern was observed for heart although the absolute magnitude of hypertrophy was no more than 20-30%.

Temperature acclimation in the channel catfish, Ictalurus punctatus: Seasonal variation and cellular mechanisms
… acclimation for total liver protein and DNA, hepatosomatic index, and activity of pentose phosphate shunt enzymes, while spring and summer fish showed little or inverse compensation. LDH showed little compensation or seasonal variation in either liver or muscle. Cytox showed seasonal variation …

Assessment of Largemouth Bass (Micropterus Salmoides) Condition Using Liver Histopathology, Health Parameters and Water Quality Of The Central Chattahoochee River Watershed
… histopathology and the degree of tissue change index (DTC), hepatosomatic indices (HSI), relative weight, condition factors, and intersex. These health parameters as well as water chemistry data were compared across four bodies of water, three within the Chattahoochee watershed, and one …

The anti-estrogenic and liver metabolic effects of DHAA in rainbow trout (oncorhynchus mykiss)
… exposure to 5 ppm of E2 significantly increased hepatosomatic index (HSI), vitellogenin (VTG) and plasma sorbitol dehydrogenase (SDH). This effect was reduced by mixing E2 with DHAA, indicating that DHAA does not cause its anti-estrogenic effects indirectly due to liver damage. Exposure to 5 ppm …

The effects of Hydroxypropyl-β-Cyclodextrin on the American Flagfish (Jordanella floridae) over one complete life-cycle
… observed in growth, condition factor (K) and hepatosomatic index (HSI) when chronically exposed to HPβCD (P ≤ 0.05). A significant increase in female gonadosomatic index (GSI) occurred in those exposed to HPβCD (P ≤ 0.05). A reduction in the time to reach steady-state spawning occurred at 1600 …

The effects of an unidentified pathogen, ‘Frill on Gill’, on body condition of Cape hake Merluccius capensis, on the south coast of South Africa
… body condition measures, condition factor and hepatosomatic index (HSI). A total of 24275 M. capensis were sampled, of which 825 (3.4%) were infected with the FOG pathogen. The smallest M. capensis infected with FOG was 10 cm, and the largest was 84 cm. The smallest uninfected M. …

Bioenergetic and ecological consequences of diet variability in Atlantic croaker Micropogonias undulatus
… (K), relative weight (Wr), energy density, hepatosomatic index (HSI), and gonadosomatic index (GSI). Of these condition measures, several morphometric measures were significantly positively correlated with each other and with the percentage (by weight) of anchovy in croaker diets, suggesting …

Breeding Design for Atlantic Cod (Gadus morhua L.)
… yields such at fillet yields (h2 = 0.04) and the hepatosomatic index (h2 = 0.061) is less promising for obtaining genetic improvement. The strong phenotypic and genetic correlation (rG = 0.9) in body weight and maturation suggests that an increased growth rate will consequently lead to a higher …

Sexual maturation in sea- and freshwater phases of Pacific salmonids and investigations of reproductive hormone involvement in osmoregulatory adaptation
… and at the post-spawning stage. Gonadosomatic index (GSI), hepatosomatic index (HSI), and oocyte germinal vesicle stage and hydration level were measured in sacrificed chinook and steelhead. Stamp River steelhead were serially sampled for blood during the month preceding and the month following …

Influence of Diet and Environmental Variation on Physiological Responses of Juvenile Pallid Sturgeon (Scaphirhynchus albus)
… (86%) of chironomid prey. In contrast, the hepatosomatic index (HSI) was significantly higher (44%) in fish fed formulated feed, indicative of a high lipid diet. Natural feeds resulted in superior growth and condition than formulated diets. Use of a natural diet prior to stocking may …

Assessing Brook Stickleback (Culaea inconstans) as a bioindicator for endocrine disrupting compounds in aquatic environments
… Exposure to EE2 also significantly increased the hepatosomatic index in females after 7 days and in both sexes after 21 days whereas the gonadosomatic index was reduced in females after 21 days. An increase in kidney epithelium cell height was also observed in MT-exposed females and males after 7 …

Applying edge-core theory of intraspecific life-history variation to the control of invasive silver carp (hypophthalmichthys molitrix)
… reproduction, growth, and health. Gonadosomatic index, reproductive hormones, and gametogenesis were analyzed in male and female silver carp collected from the La Grange and Starved Rock reaches between April-October 2018, and gametogenesis was analyzed in silver carp from the La Grange and …
