  1. Cease or prohibit all types of fishing

    A site comparison study in 2004 in areas of soft sediment in the southern North Sea, Netherlands (Duineveld et al. 2007) found that an area closed to all fishing had different invertebrate community composition, and higher species richness, compared to fished areas, after approximately 20 years. Community data were presented as graphical analyses, and richness data were presented as diversity indices. A gas production platform was drilled approximately 20 years prior to the study and a 500 m zone closed to all trawling, established around it. In April 2004, invertebrates were surveyed inside the closed area and in four sites (1 x 1 nm) outside (1.5 nm north, south, east and west of the exclusion zone). Samples were collected using a combination of dredge (6–10 tows/site; invertebrates >7 mm) and sediment cores (seven cores/site; invertebrates >1 mm) at 36–39 m depth. Invertebrates were identified and counted.
