Abstract

Statewide Pacific ocean shrimp, Pandalus jordani, landings totaled 2,033.1 mt (4,472,749 lb) down 204.6 mt (450,108 lb) from the 1979 catch of 2,237.7 m t (4,922,857 lb). The 1980 landings are the lowest since 1976 when 1,545.5 mt (3,400,191 lb) were landed. Area A (Eureka-Crescent City) landings dropped to 1,234 mt (2,716,147 lb) from 1,842.5 mt (4,053,605 lb) landed during the previous season. Area B-1 (Fort Bragg) landings totaled 79.3 mt (174,395 lb) from catches made during the last 9 days of the season. Only 100 lb were reported caught in Area B-2 (Bodega Bay). Record landings of 719.1 mt (1,582,107 lb were made in Area C (Morro Bay-Avila), surpassing the previous record of 391 mt (864,667 lb) landed in 1979. In Area A a record 80 vessels, 34 double-rigged and 46 single-rigged, made shrimp deliveries during the season. Average catch per hour was a very low .ll mt (234 lb) and .20 mt (446 lb) for single- rig and double-rig vessels, respectively. In Area C average catch per hour was .25 mt (557 lb) and .21 mt (462 lb) for single-rig and double-rig vessels, respectively. Area A shrimp catches were dominated by 1-year-old shrimp in percent by number throughout the season. The age composition in Area C shifted from predominately 2-year-old shrimp in April, May, and June to predominately 1-year-old shrimp for the remainder of the season. Area A was closed for one month from June 1 to July 1 because closure criteria of less than .16 mt (350 lb) per hour for two consecutive weeks was met and year class composition exceeded 70% of year-old shrimp. The season was closed for the year on August 25 when the catch per hour and percent 1-year-old shrimp criteria was exceeded again. (22pp.)
