The Canadian and Icelandic catches were transferred at sea for delivery to the Gloucester firm. The Canadian vessels are 100-foot-class combination purse seiners-otter trawlers, equipped with power blocks and sonar. These vessels fish with a seine skiff and fish seines 40 to 50 fathoms deep, and 250 to 350 fathoms long. Thq Icelandic vesselused a 120-fathom- deep purse seine. BCF Explorations In April, BCF's exploratory fishing re- search vessel 'Delaware 11' conducted sur- veys to locate and sample commercial abun- dance of herring and red hake concentrations. Surveys and experimental fishing were car- ried out with a midwater trawl and a high- opening bottom Study Spring Spawning of Georges Bank Haddock The 1969 spring spawning of Georges Bank haddock was followed carefully by BCF's Woods Hole (Mass.) Laboratory. A sampling schedule was set for January-July with weekly samples from the commercial fleet and from BCF's 'Albatross IV. Arrangements were made with Boston trawler skippers to supply fish landed in the round to provide gonads for examination. Observations Began in 1968 The study continues observations begun in 1968. It was noted then that peak spawn- ing did not occur until late April. This was considerably later than indicated by plankton surveys in previous years. The Georges
