| Movement activity and localization of food were studied dynamically with the objective of establishing the capacities of behavioral adaptation of the young Dicentrarchus labrax faced with a novel situation. The role played by previous rearing conditions was demonstrated, the level of stimulation being a sensitive intervening factor (currents associated with the food). The data show the favourable effects of such treatment, and are in agreement with work carried out on higher vertebrates, which have brought to light the importance of early stimulation in behavioral ontogeny which respect to emotionality as well as capacities of adaptation in subjects reaching adulthood. |

| A characteristic feature of flatfishes (order Heterosomata) is the absence of pigmentation on their blind side. Asymmetric colouration is related to body asymmetry and with the bottom-dwelling habit of these fish. Pelagic larvae are symmetrical and usually possess chromatophores on both sides of the body. When one of the eyes migrates to one side or the otherto the left or to the right and the larva settles on the bottom, the chromatophores on the blind side disappear. In certain fishes, such as Reinhardtius, Glyptocephalus, Taeniopsetta, etc., the blind side is usually brownish grey since that is where the melanophores develop. In turbots (Scophthalmus maximus), the blind side is often yellowish brown and in this case, fishermen call them "double... |
