Novel approach to study fish DNA collected from water samples enables researchers to estimate biomass of multiple Alaska fish species simultaneously. Around the world, standard ways to measure fish abundance and biomass to manage commercial, recreational and subsistence fisheries rely heavily on deriving estimates from fish caught in research surveys and commercial fishing nets and […]
Alaska Department of Fish and Game (ADF&G) biologists plan to begin aerial surveys of the Togiak district herring fishery in mid-April, weather permitting, with regular fishery updates to be communicated directly to processors. Based on a forecast of a 136,756-ton biomass, 27,351 tons of herring will be available for harvest. The breakdown is 1,500 tons […]

How many insects are stirring on the surface of Alaska? That’s a fun but hard-to-answer question that Derek Sikes recently pondered in response to writer and wilderness guide Michael Engelhard. I […]
Alaska fishery area management biologists in Dillingham say the 2015 Togiak District herring biomass is forecast to be 163,480 tons, about 110 percent of the recent 10-year average. The forecast issued in late February is based on an age-structured analysis model in use since 1993. It shows so far that herring ages 4-6 are expected […]
