It is in Tahiti. For two or three years on the same beach, I have been watching Lou, an unrepentant fishing dog: every day, from morning to dusk, Lou stalks his prey, sometimes with a certain frenzy stimulated by the episodic presence of a few competitors.
Most of the time, he just sits on his little coral potato a few metres from the shore. Thus immersed up to his chest, solitary and immobile on his promontory, he watches for the fish that will come to him. Except that I have never seen him catch anything. Nor have I ever seen him dip his nose in the water! I wondered if he wasn't actually paid by the research lab of Moorea (the CRIOBE) to count the fishes !

In fact, during my recent little aquatic walks, I noticed precisely that there were less and less of these marvellous colourful, coral-grazing fishes there, yet abounding in my memory of these now familiar bottoms.
