１隻でサンマもイワシも　不漁対策、「脱専業」提言―水産庁検討会

　水産庁の「不漁問題に関する検討会」は４日、漁獲量が近年急減しているサンマ、スルメイカ、サケの不漁対策の方向性を示す報告書をまとめた。漁業経営の維持へ、１隻の漁船で１種類の魚を漁獲する専業的漁業から脱却し、資源量が増えているマイワシなど、複数の魚を狙う操業形態への転換を促すことが対策の柱。水産庁は具体的な支援策を詰める。
　報告書は、３魚種の不漁の要因に地球温暖化の進行などを挙げた。不漁が特に深刻なのはサンマとスルメイカ。２０１９年の漁獲量は、サンマが約４万６０００トン、スルメイカが約４万トンと、いずれも最盛期から９割以上減り、過去最低水準にある。
　水産庁は魚種ごとに漁獲上限を設けて資源管理の徹底を図ってはいる。しかし、報告書は、海洋環境の変化により、「（不漁が）長期に継続する可能性がある」と指摘。サンマとスルメイカでは中国など外国船の乱獲も響き、資源回復の見通しが立っていない。（2021/06/04-19:16）

A panel of Japan's Fisheries Agency in a report Friday called on fishers to shift away from their current practice of catching only one variety of fish per vessel as a solution to recent poor catches of saury, Japanese flying squid and salmon.
   They are encouraged to catch multiple varieties of fish, including sardine, whose stock is increasing. The agency is set to work out details of support measures.
   The report partly attributed poor catches of saury, Japanese flying squid and salmon to an increase in global warming. Saury and Japanese flying squid catches in 2019 stood at record-low levels of 46,000 tons and 40,000 tons, respectively, both down more than 90 pct from their peaks.
   The agency is working to manage fish resources strictly by setting a catch limit for each species. But the report warned that poor catches of the three fish varieties "may continue for a long period of time" amid changes in the marine environment.
   A recovery in saury and Japanese flying squid stocks remains uncertain also due to overfishing by Chinese and other foreign fishing vessels.
