Five surveys were carried out by T.G. Skinner in the Solway Firth Areas. Surveys were carried out with plankton nets and a count of the species captured was carried out. This survey is the third survey and is documented in the following three papers: The Seasonal Occurence of Some Prominent Zooplankton Species in Rough Firth between March 1984 to March 1986. I. Scyphomedusae (Glasg. Nat. 22 Part 5: 471-484 (1995)), The Seasonal Occurence of Some Prominent Zooplankton Species in Rough Firth. II. Chaetognatha (Glasg. Nat. 22 Part 5: 479-484 (1995)), and The Seaonal Occurence of Some Prominent Species in Rough Firth. III. Decapod Larvae. (Glasg. Nat. 23. Part 1: 51-56 (1996)).
