Fish Juvenile Growth Study

Fish Juvenile Growth Study

Exponentially growing larvae are weighed and placed in test chambers, usually exposed to five sublethal concentrations of the test substance dissolved in water, preferably with flow-through or, if not possible, at an appropriate semi-lethal concentration. static state. The test duration is 28 days. Daily food rations are based on the fish's initial weight and can be recalculated after 14 days. The testing services provided by CD BioSciences include the concentration measurement of the test substance, the observation of external anomalies and abnormal behavior, and the weighing of the fish at the end of the experiment. Our scientists analyzed the effect on the growth rate using a regression model to estimate the concentration that would cause an x % change in the growth rate. Alternatively, the data can be compared to control values to determine the lowest observed effect concentration (LOEC) and no observed effect concentration (NOEC). We offer this test to assess the effects of long-term exposure to chemicals on the growth of juvenile fish.

Our Services

Our scientists have amassed a vast understanding of fish biology and their experimental manipulations. We combine this expertise with the use of automated equipment and data analytics solutions powered by AI. Our services are listed as follows, but are not limited to:

  • Rainbow trout juvenile growth study
  • Zebrafish trout juvenile growth study
  • Oryzias latipes trout juvenile growth study
  • Gasterosteus aculeatus juvenile growth study

Endpoints of Fish Juvenile Growth Study

During the test period, the fish will be observed daily for survival, abnormal appearance, and behavior. In addition, at the end of the test, the weight of all surviving fish will be determined. The specific growth rate will be calculated and analyzed for the concentration that would result in a change in the x% growth rate. Estimate the lowest observed effect concentration and the non-observed effect concentration.

Key Features of Our Services

  • Typically, 5 concentrations in one geometric row and one control are tested.
  • We present the results of acute toxicity tests performed on the species selected for this test.
  • Fish will be fed daily and food rations will be based on initial fish weight. At the end of the test, the fish were weighed again.
