A question about that - did anyone ever try this, in the exact periods of the year that they normally spawn in the wild ?
Seasonal breeding species have a adapted/evolved an annual cycle, in which the gonadosomatic index and hormone levels are exactly adapted to these natural seasons...
For example, an attempt in the period august to januar, will probably fail because in the wild, this is the "post spawning" period in which the gonadosomatic index as well as the hormone levels, are just too low for a succesfull spawning.
Taking into account both seasonal simulation ánd these reproduction biological factors, best chances for a succesfull spawning would be to start the simulation in April / May, and try a spawning in June / July.
Has anyone ever tried this, and care to share their experiences on it ?
