(Our previous reports on relatively abundant fishes used 49% for jack mackerel, 20% for Pacific saury, and 50% for Pacific hake.) Blunt and Parrish estimated the present spawningbiomass of Pacific mackerel at less than 5,000 tons. They stated further that "Certain environmental factors detrimental to good recruitment are indicated and if this continues through 1969, long term loss of the fisheries is a distinct ; In 1969, California landings were 1,178 tons; no fig- ures are available for Baja California land- ings for that year. Legislature Acts On March 31, 1970, the California legis- lature passed a bill providing that "Pacific mackerel may not be taken or possessed at any time for any purpose except loads or lots of fish may contain 18% by weight of Pacific mackerel taken incidentally to other fishing operations. Such Pacific mackerel, inciden- tally taken, may be used for any ; This is a2-year act to ". . remain in effect only until the 61st day after adjournment of the 1972 Regular ; On August 14, the Governor of California signed the bill into law. It will go into effect on November 25, 1970. LITERATURE CITED AHLSTROM, ELBERT H. 1956. Eggs and larvae of anchovy, jack mackerel, and Pa- cificmackerel. Calif. Coop. Oceanic Fish. Invest.
