Changes in trawl-survey operational protocols throughout the time may affect trend information.

Changes in trawl-survey operational protocols throughout the time may affect trend information. This paper aims at estimating the relationships between two different pre-hauling protocols and depth, in order to suggest correct factors suitable for the time series analysis.
