Dear fellows

I had publised at J. Fish Biology a mathematical model describing growth with seasonally varying temperatures (J. Fish Biol. 48:569-584, 1996). Now I am working improving that model to fit seazonal growth associated with river water level transbording to wet plains. The data I need are monthly length measurements of an age-group of fish and the mean water level at each month. The data could be published or not. If original, a conjunt publication could be done.

Thanks,
