An experimental vertical line trawl was fished sev- eral times at night--whiting and hake were caught, but no ocean perch. Efforts to tag ocean perch proved fruitless. Even the ocean perch brought to the surface from shallow depths of 35-40 fathoms were badly blown and unable to return to the bottom. A 4 ft 4 A ZERO-AGE HADDOCK DISTRIBUTION STUDIED BY "ALBATROSS in" (Cruise No. 54): A 13-day cruise to collect data to determine the distribution and numbers of zero-age haddock in connection with early life history and year-class strength studies was completed by the Service's research vessel Albatross III at Woods Hole, Mass., on September 14. The area covered was Georges Bank and the Gulf of Maine. Zero-age haddock were found in a very limited area (South Channel and the Gulf of Maine) while yearling fish of other species were more widely dispersed. No young haddock were found off the bottom. Sixty-seven 20-minute tows with a No. 36 trawl were made throughout the area. One-hundred bathythermograph lowerings were made. In addition, at selected stations horizontal tows with a 1-meter ring net attached to the towing warp were made. Further analysis of the distribution of zero-age haddock will have to await the com- pletion of a similar sampling of the Southern
