Sea surface temperatures are between 13°C. and 15°C. Average tows produce between 50cc and l00cc of plankton. Obelia geniculata is very abundant and Pleurobrachia pileus is common, but together they comprise only about 50% of the volume. Fish eggs and larvae are still very common, but these do not occur in the abundance characterising the previous three months. In comprising about 45% of the volume, larval Crustacea are more abundant than in any other month of the year. Squilla armata larvae are very common with early stage larvae dominant. Forty-six larval decapod species are recorded with Callianassa filholi the most abundant species.
