“…Until now, a numerous of egg characteristics have been used for evaluation of egg quality. These characteristics are: morphological state of eggs (Bromage, 1995), estimation of the percentage of overripe eggs (Barnes et al, 2000), determination of the relative weight increase during 30 min of hardening after fertilization (Lahnsteiner & Patzner, 2002) and measurement of biochemical parameters of ovarian fluid and eggs (Lahnsteiner et al, 1999;Lahnsteiner, 2000). All mentioned procedures are time and cost consuming and require additional skilled laborand and equipment.…”

To identify a simple tool for quick evaluation of quality of endangered Caspian brown trout, Salmo trutta caspius eggs, the changes of pH (both in ovarian fluid and fertilization water), turbidity (both in ovarian fluid and fertilization water), fertilization and eyeing rates were investigated in ovarian fluid samples containing perfect eggs as well as different concentrations of broken eggs. The pH of ovarian fluid and water as well as fertilization and eyeing rates decreased significantly (P<0.05) with increasing of broken eggs in ovarian fluid. In contrast, the turbidity of ovarian fluid and water as well as mortality rate of eggs increased significantly (P<0.05) with increasing of broken eggs in ovarian fluid. Also, significant correlations (P<0.01) were found between measured parameters as follow: pH of ovarian fluid vs. pH of water and fertilization and eyeing rates; turbidity of ovarian fluid vs. turbidity of water; turbidity of ovarian fluid and water vs. fertilization and eyeing rates. Our results conclude that pH and turbidity of ovarian fluid and water effectively influence on efficiency of artificial propagation. Therefore, these could be used as two simple tools for quick evaluation of quality of Caspian brown trout eggs during artificial reproduction in the hatchery.

“…Because of the high prevalence of overripe and nonviable spawns in Lake Oahe Salmon [38], it is possible that thiamine was degraded due to cell death and not because of the action of thiaminase. Twelve of the spawns in the current study had no survival to the eyed-egg stage of development, and were likely nonviable prior to spawning.…”

We assessed the turbidity measurements of ovarian fluid and ovarian fluid mixed with lake water, distilled water, and well water for their potential to predict egg survival of landlocked fall Chinook Salmon Oncorhynchus tshawytscha from Lake Oahe, South Dakota. Turbidity of the ovarian fluid alone ranged from 23.1 to 101.7 NTU, and mean turbidity increased with the addition of any of the water sources. Egg survival to the eyed stage ranged from 0% to 61%, and was not significantly correlated with ovarian fluid turbidity or the turbidities of any of the ovarian fluid and water combinations.
