PurposeResearch
ObjectivesTo participate in an international survey of the distribution of abundance of adolescent herring in the North Sea by trawling and plankton sampling.

''Explorer'' was anchored in the Forth from the 09/03/1967 for 3 days due to a deterioration in the weather. Arrangements were made to do a comparative fishing experiment with the research vessels ANTON DOHRN and CLIONE. The trawl of the ''Explorer'' was badly torn in hauling the first trawl of the experiment and the other 2 ships continued shooting till the weather deteriorated to preclude shooting again.

Herring and white fish (haddock, cod) catches were made. A considerable number of ovaries for fecunditiy determination were collect from the various positions fished.
