Condition factor and hepatosomatic index as estimates of energy status in male three‐spined stickleback

Journal of Fish Biology, 1995
Seasonal variation in direct and indirect measures of energy status was examined using estimates of glycogen, lipid and protein levels in a single cohort of male three‐spined sticklebacks from an annual population collected each month over one complete year.

Variations in hepatosomatic index and biochemical profiles among the male morphotypes of Macrobrachium rosenbergii

Aquaculture, 1999
Abstract Hepatosomatic indices and biochemical profile of the male morphotypes of Macrobrachium rosembergii such as small males, weak orange clawed males, strong orange clawed males, pre-transforming strong orange clawed males, weak blue clawed males, strong blue clawed males of grow-outs and old blue clawed males from the Vembanad lake were ...

The Dependence of the Duration of Downstream Migration of Burbot (Lota lota) Larvae on the Hepatosomatic Index of Spawners

Russian Journal of Ecology, 2019
This study estimates the dependence of the duration of the downstream migration of burbot larvae in the Voikar River (the Lower Ob basin) on the relative condition factor of semianadromous spawners migrating upstream to the spawning tributary in autumn; the estimates are based on 20 years of observations (from 1999 to 2018). The observed (11 years) and

Short-term effects of wildfire ash exposure on behaviour and hepatosomatic condition of a potamodromous cyprinid fish, the Iberian barbel Luciobarbus bocagei (Steindachner, 1864).

Science of the Total Environment, 2019
Wildfires are a common phenomenon in Mediterranean regions that is becoming increasingly frequent and severe, causing several environmental concerns, of which ash runoff represents an important source of disturbance for aquatic organisms, in particular ...

The reproductive biology of the dab Limanda limanda (L.) in the North Sea: gonosomatic index, hepatosomatic index and condition factor

Journal of Fish Biology, 1978
Measurements have been made of the annual cyclical changes in gonosomatic index (GSI), hepatosomatic index (HSI) and condition factor (K) in male and female dab Limanda limanda (L.). There is a direct correlation between HSI and K, and an inverse correlation of these factors to GSI but with a three month lag. It was also found that the lower (‘ventral’)

Hepatosomatic index and haematological profile: A bio monitoring tools for assessing african catfish juveniles (Clarias gariepinus) exposed to dimethoate 40% EC toxicity

Tropical Freshwater Biology, 2023
Organosomatic and Haematological Indices are commonly reported in fisheries studies because they are easily determined and can be excellent predictors of adverse health in fish. The objective of the present study was to evaluate the toxicity effect of an
