Effects of forebrain ablation on growth in teleost fishes.
The effect of forebrain extirpation on food uptake and growth was studied in different teleost species. In the case of wild species such as Carassius gibelio and Macropodus opercularis concolor, a prolonged enhancement of food uptake and body growth was found following forebrain ablation. In the case of domesticated species such as the common goldfish (Carassius auratus) and Macropodus opercularis, there was no effect of forebrain extirpation on either food uptake or growth.
