Fish Chronic Toxicity Test

Chronic toxicity tests are designed to measure the effects of toxicants on aquatic species over most of the organism's life cycle. Among aquatic species, fish are more sensitive to poisons due to direct contact with water bodies, so the risk of poisoning is higher than other aquatic animals. To assess the potential toxicity of a test substance, chronic toxicity tests are usually performed on fish. Chronic studies assess the sublethal effects of toxicants on reproduction, growth, and behavior resulting in physiological and biochemical disruption. Effects on survival are most often assessed, but they are not always the primary objective of research. Such experiments require a controlled, reproducible environment and standardized protocols to ensure accurate results. If the chemical resulted in death, it could be considered chronic toxicity, sublethal effects, or a change in the behavior of the fish following exposure. To ensure reliable results, CD BioSciences' chronic toxicity tests protocols are standardized and follow the guidelines established by regulatory agencies.
