CALIFORNIA FISH AND GAME 231 METHODS OF FISHING. Time. It is the fixed opinion of some that day fishing yields more mixed or small sizes of fish than night fishing; others notice no difference. Large and small fish are caught both day and night, but it may easily be true that differences in the schooling of the fish make the larger fish more accessible at night and so increase the average size of the fish in the total catch. At any rate, the demands of the canneries for large fish—pound oval size—combined with the greater accessibility is respon- sible for the greater part of the sardine catch being taken at night. The fish are most easily located on the darkest nights, hence, the two- week period during the dark phases of the moon is most successful. Day fishing is only resorted to when less than two or three hours of darkness is left between nightfall and moon-rise or moon-set and dawn. When fishing in the day time, the hours of early morning are the most favorable as the schools of fish can be most easily located when the water is Fig. 7i. Searching for schools of fish. The crew on the bow and the man on the pilot house anxiously scan the sea for birds, darkened areas of water, or ripples on the surface which indicate the presence of fish. A typical Japanese boat. Locating the school of fish. The schools are located at night by the phosphorescent light produced by the movement of the fish in swimming. This explains the depend- ence of the fisherman upon the phases of the moon, as even a small amount of moonlight, or even bright starlight, makes it difficult at times to see the pale light of the phosphorescence. The running lights of the fishing boats are even darkened by covering them with cloth so that they may be seen at a short distance by other boats but will not give enough light to obsc
