Abstract
The bottom fauna within a radius of 15 miles from Port St. Mary, was surveyed during the period July 1946 to April 1950. Gear used included trawls, dredges and a 0.1 m.2 Van Veen bottom-sampler. Four types of deposit were distinguished: (a) coarse sands, gravels including shell, and stony ground, (b) fine sand, (c) muddy sand, (d) mud. Their limits are mainly fixed by wave action and the strength of the tidal currents. Each type of deposit carries a distinct faunal assemblage which may be considered as a main community. The fauna is not evenly distr. within each community area, but further subdivision was unjustified. An account is given of the communities and of the chief variations within them, with lists of the more important animals. The fauna has only a slight preponderance of southern against northern forms. The biomass estimated from quantitative samples shows a poor production of benthos compared with that in some other areas.This publication has 3 references indexed in Scilit:
