Abstract/Description

Zebrafish are one of the most common models used in biological research. Successful maximization of reproduction of zebrafish in a laboratory setting is important for this reason. There is conflicting evidence among published studies, anecdotal evidence, and industry practices about what spawning conditions maximize spawning success. This study tested the main areas that affect spawning success: sex ratio, environment, age, and seasonality. To measure reproductive success, clutch probability and average clutch size was used. Clutch probability and clutch average were shown to be significantly affected by habitat substrates and season. This data supports the implementation of steps to maximize reproductive spawning success in laboratory zebrafish.
