Description | |
Summary | The initial survey in 1989 estimated the biomass of cockles at tidal heights above that exploited using current commercial methods. The 1990 survey (March - April) and subsequent surveys sampled all parts of a limited number of beds. Surveys from 1991 to date have taken place in September after recruitment has been completed. The 1997 survey again included areas not normally exploited commercially. The survey now covers 7 sites, approximately 240 samples being collected from predetermined sites located on a regular latitude - longitude based grid. All terrain vehicles are used for transport across the beds. |
