Critical light levels necessary to produce avoidance movements in photonegative free embryos (eleutheroembryos) of the lake and brook charr and their F1 hybrid splake, (S. namaycush X S. fontinalis) were determined and compared to previously studied movement patterns within artificial substrate systems. Light sensitivity was inversely related to depth of… CONTINUE READING
