TINRO-Center scientists sampled and sampled 5,600+ pollock individual species, 1,000+ herring individuals and nearly 1,000 by-catch species for biological analysis during fishing season A-2017 in the Sea of Okhotsk.
Enhanced laboratory-level colloquiums held in TINRO-Center on May 18-19 reviewed reports delivered by scientists who worked as at-sea scientific observers in the Sea of Okhotsk pollock fishery during the winter—spring fishing season (season A 2017).
12 TINRO-Center observers had been deployed onboard of commercial trawlers under the Pollock and herring monitoring program in the Sea of Okhotsk and as part of cooperation with the Pollock Catchers Association.
Scientific observers reported that they have worked about 1,000 ship-days at sea (January – first 10-day period of April). They have examined 850 trawl hauls, measured and dissected more than 150,000 pollock individual species, 30,000 herring individuals and more than 4,700 by-catch species individuals. They also sampled more than 5,600 pollock individuals, more than 1,000 herring individuals and nearly 1,000 by-catch species individuals for full biological analysis.
Scientists also performed daily observations of seabirds and mammals accidental mortality and by-catch during the pollock trawling operations. These observations have covered virtually all areas of fishing operations.
In addition to TINRO-Center observers, there were also five observers from FGBNU “KamchatNIRO” and one observer from FGBNU “MagadanNIRO”. It is worth noting that this fishing season was a record-high in terms of the total number of observers (18 persons), number of processed and analyzed fishing efforts (about 1,000), number of biological tests of pollock and by-catch species (more than 200,000 individuals) compared with preceding years.
Researchers of the Pollock and Herring Laboratory of TINRO-Center and other invited specialists are currently summarizing and analyzing collected materials.
