Fish Bulletin 131. The Structure, Development, Food Relations, Reproduction, and Life History of the Squid Loligo opalescens Berry

The squid, Loligo opalescens Berry, is abundant along much of the west coast of North America. They often congregate where a light is suspended over the water at night, and at certain seasons, individuals that are spent by spawning may be seen swimming aimlessly near the surface. Great schools spawn in shallow waters like those adjacent to Monterey, California, where they support a valuable fishery. This squid is also important as food for many fishes, sea birds, and marine mammals.
