Abstract
The suitability of a single intertidal fish trap for the assessment of long-term trends in fish and epibenthic invertebrate relies upon the assumption of an on-average constant sampling fraction from the study population. This assumption was examined by comparing trends over year s in five different traps within the study area. For some species, lik e cod, the traps showed more or less parallel fluctuations. This is in agreement with the assumption. However, for other species, like macke rel, the assumption was invalidated by distinct trends over years.
