5203 |a"Coastal waters within the 50-200 m bottom contour of Hecate Strait were surveyed to determine Pacific herring abundance estimates and distribution patterns. Total midwater biomass estimates for herring were 11,300 tonnes at Browning Entrance, 2,820 tonnes SW of Bonilla Island, 510 tonnes along Butterworth edge, 620 tonnes in mid-Hecate Strait, 920 tonnes off Lyell Island and 14,620 tonnes in Juan Perez Sound. Herring schools were difficult to integrate acoustically in inlets and narrow sounds because of bottom echo interference and high herring densities near the surface at night. Species composition of thirteen midwater trawl and nine bongo net catches, stomach contents and size and age distribution of herring were also examined. Seawater temperatures were collected at six X.B.T./trawl locations"--Abstract, page iii.
