| Abstract |
The suitability of intertidal fish traps (fykes, kom-fykes and koms) to study long-term trends in juvenile flatfish (plaice, flounder, dab and sole) was analysed with respect to effects of location, type of trap and fishing duration. For all species, catches by the three different types of fykes and on the three locations studied differed considerably, but the patterns over time were approximately the same. The results further suggest that kom- fykes have the highest catches of flatfish and koms the lowest. The similarity in fluctuations of catches between fish traps and between locations suggest that they may be suitable for the study of long-term changes in flatfish populations. For all species, increasing fishing duration from 24 to even up to 96 h hardly resulted in higher catches. |
