Many of the characteristics of walleye pollock early life history are common to all populations of the species. In the Bering Sea, however, both the population structure and early life history pattern are much more complex than in the Gulf of Alaska. Genetic characteristics [ Mulligan, 1992] and length-at-age and fecundity relationships [ Hinckley, 1987] suggest several spawning stocks exist. The importance of pollock in the ecosystem [e.g., Springer, 1992], as well as the relationships and interchange among stocks are largely unknown. Spawning begins earlier in the year in some parts of the Bering Sea than it does in Shelikof Strait and apparently different groups of fish spawn at different times and places. We began our efforts focusing on the population that spawns in February over the southeastern slope, and supported a substantial fishery in the late 1980's. Here we found indications that some of the eggs and larvae were much deeper in the water column (400 m) than we had found in Shelikof Strait. Also, feeding conditions did not seem to be adequate for optimal growth in this area. We found larvae associated with eddies in this area as we had in Shelikof Strait. Our attention is now focused on the spawning (April-June) that occurs over the continental shelf of the southeastern Bering Sea.
