compensation depth, so that phytoplankton production > respiration. Tropical growth seasons are continuous. Fish larvae grow best in the temperate regime characterized by a long growing season with an initial time lag in the spring. Variations in the length of the growing season may cause mass mortalities or outbreaks of red tides, and are most likely at the temperate/tropical boundary zone.

Enchytraeid oligochaetes as marine pollu- tion indicators. Mar. Pollut. Bull., 11(6): 171- 174.

The presence of enchytraeid oligochaetes (15 species from the genera LumbriciUus, Marionina and Enchytraeus) is related to the presence of pulp mill wastes and it is suggested that LumbriciUus lineatus, as a percentage of total adul t enchytraeids, can serve as an index of the impact of pulp mill effluent in intertidal areas.

tion of the feeding behavior of marine copepods by sub-lethal concentrations of water-accemmodated fuel oil. Mar. Biol., 56(1): 59-64.

Effects of low concentrations of No. 2 fuel oil on the feeding rates and selectivity of two coastal marine copepods (Acartia clausi and A. tonsa) are described. Concentrations of 250 t~g L ~ were found to quantitatively and qualitatively alter feeding behavior. Results suggest that Acartia use three different modes (particle-size related) of feeding and that low-level hydrocarbon contamination affects each feeding mode differently.

The impact of the Amoco Cadiz oil spill (March, 1978) on the benthic infauna community in an eelgrass (Zostera marina L. ) area was investigated. It was found that after a sharp decrease in numbers of individuals and species (almost total dis- appearance of Crustacea and Echinodermata), recovery, began rapidly and, with the exception of filter-feeding Amphipoda, numbers were returning to normal after a year.
