A Comparison of the Zooplankton in Two Newfoundland Bays with Differing Influences from Major Currents
Abstract Quantitative zooplankton samples were obtained at four regular stations and one irregular station in Placentia Bay, Newfoundland between mid June 1974 and mid May 1976. Sampling was attempted fortnightly as regularly as weather conditions and competition from other ship users would allow. T...

| Summary: | Abstract Quantitative zooplankton samples were obtained at four regular stations and one irregular station in Placentia Bay, Newfoundland between mid June 1974 and mid May 1976. Sampling was attempted fortnightly as regularly as weather conditions and competition from other ship users would allow. The results are compared with those obtained and previously published in a similar study from Conception Bay, Newfoundland in 1977 to 1978. There was a greater diversity of species in Placentia Bay, and for most species the numbers/m 3 were greater. The two bays are influenced by somewhat different current systems, and climatic conditions are a little milder and foggier in Placentia Bay. The same species were common in both bays, with copepods usually being the most important. Among copepods, two of the most important species namely Pseudocalanus sp. and Oithona similis were less abundant in Placentia Bay, but this was offset by a greater abundance of Temora longicornis. A few of the problems that require further investigation are outlined. |
