The objectives of the cruise were to count, sample, and identify mid- water schools in that area, and to test midwater trawls of vary- ing mesh sizes. A total of 52 midwater- trawl sets (see chart) were made on depth-recorder indications of midwater schools. Catches of 10 to 1,369 pounds were obtained in 36 tows, and indicated concen- trations of many species of her- ringlike species. Eighteen of the schools Sctmpled were predomi- nantly razor bellies (Harengula pensacolae) and nine were 5- to 6-inch anchovies (Anchoa hep- setus). Scattered schools sam- pled contained mixtures of thread herring, chub mackerel, round herring, anchovies, scad, gizzard shad, and alewives. Menhaden (Brevoortia patronus) made up the bulk of the catch in two drags off Pass-a-Loutre. One drag (Jan- uary 30, 1958) contained 1,290 pounds of menhaden in ripe spawning condition. m/V OREGON CRUISE 48 (JANUARY 27-MARCH 14, 1958). Two 40-foot square midwater trawls with mesh sizes tapering from 3" to 1:^" and 2" to if" were used for school sampling. A single set on three dense school indications with an 88-foot nylon trawl resulted in the loss of all the netting. Recorder indications of subsurface schools were numerous both preceding and following the cold wave during the middle of February. Schools were noticeably diminished during the cold wave.
