Squid jig Fishing Log data collected during NOAA R/V Townsend Cromwell cruises in 1982 and 1983 and during 1981-1983 research cruises of the Hokusei Maru, a Japanese research and training vessel. Collected data includes date, latitude, longitude, species, catch and effort data.

This is a federally mandated log which is required to be mailed in to NMFS after a fishing trip. This data set includes transshipment and sales information for a lobster fishing trip. There is only data from one year, either 1994 or 1997 (verification is ongoing).

This data system contains the logbook data of vessels unloading in American Samoa. In 1992, the logbooks of three longline trips conducting an experiment to test the vertical longlining concept were submitted. With the implementation of the federal longline logbook program in 1996, logbook submissions resumed. The fishing occurs in the southern central Pacific (90 deg W - 170 deg E, 0 deg S - 45 deg S). Data on interactions with protected species are also collected.

Squid morphometrics data was collected during Hokusei Maru 81-01 cruise in the main Hawaiian Islands.

This data set contains the logbook data of U.S. longline vessels based in Hawaii from 1990 to the present that fish in the central Pacific (120 deg W - 170 deg E and 50 deg N - 20 deg S). Tunas (Thunnus spp.) are the dominant species of the longline catch. Swordfish and blue shark were also numerous in the longline catch prior to April 2001. In addition, there are approximately 10 to 15 other Pelagic Management Unit Species (PMUS). Since April 2001, there have been numerous regulation changes that affect the catch and effort and fishing area of the fleet; the point of contact should be contacted for more information.

This data set contains catch and effort, landings, and observer data from longline vessels fishing in the North Pacific outside the U.S. west coast EEZ. Logbooks and landings data are available from 1991 to the present and observer data is available from 2001 to present. California-based longliners target swordfish and bigeye tunas, however, other species of tunas, billfishes, and sharks are also caught.

This data set contains gill net fishing data collected by the Hokusei Maru in 1981, 1982 and 1983, in waters around the main Hawaiian Islands. Length and weight of individual species were collected.

This data set contains catch and effort for fishing trips that are taken by vessels with a Federal permit issued for the swordfish and sharks under the Highly Migratory Species (HMS) fishery management plan. Fishermen that own vessels with permits in these fisheries are required to complete a vessel logbook for every trip in which any species in the Highly Migratory Species fishery management plans are caught and landed. Fishermen are not required to report fishing trips in which other than these species are caught. However, fishermen are required to submit a no-fishing report if they did not fish for or catch any HMS species during a calendar month. In 1986, the Southeast Fisheries Science Center (SEFSC) initiated a logbook program for vessels that held a federal vessel permit to fish for swordfish in the Atlantic Ocean and Gulf of Mexico. In 1993, a similar program was initiated for vessels with a federal permit to fish for sharks that are included in the HMS fishery management plan. In order to provide sufficient level of detail for fishing effort by the longline vessels, the catch and effort data need to be reported for each longline set. Consequently, a single logbook form was designed for the fishermen to record the catch (numbers of animals caught) and effort, which includes data on the length of the longline, the number of hooks and the duration of the set. To reduce the number of times that fishermen need to record certain pieces of information, e.g., location of unloading, duration of trip, number of crew, a trip summary form was designed in 1999 that includes the trip-related information that is the same for every set. This redesign of the logbook form resulted in two forms, the trip summary and the set forms. Only one trip summary needs to be completed for each trip, but a separate set form needs to be completed for each longline set made during the trip. At the same time, additional questions were added to the trip summary form to collect information on the expenses that the vessels incurred during the trip. Initially, this information was voluntary and the fishermen did not have to provide the cost data whereas the catch and effort data are mandatory and the vessels permit will not be renewed if logbooks are not received for every trip where swordfish and/or sharks are caught and landed.

Ichthyoplankton sampling was conducted aboard the NOAA vessel Townsend Cromwell in 9-29 July 1984 and 4-10 February 1985. Collectors included George Boehlert, James Uchiyama, Robert Humphreys, Randolph Chang, Alan Everson, Victor Honda, Bert Kikkawa, Raymond Clarke, Thomas Kazama, and Michael Seki. Two locations were sampled intensively during these cruises; one location was over the seamount summit ("seamount" location); the other location was 20 km west, over a water depth of approximately 1,800-4,750 m ("reference" location). Ichthyoplankton was sampled with an opening-closing Tucker trawl equipped with three nets and a double-release mechanism operated by messengers. The nets were 0.333 mm mesh (Nitex) with a 1.4 m2 mouth area. Ship speed was adjusted over tow speeds of about 0.9-1.1 m/second to maintain a wire angle at 45?. At this angle, the effective mouth area of the Tucker trawl is 1.0 m2 ; tow depths were estimated as a function of wire angle and meters of wire out. Four discrete depth strata (0-25, 25-50, 50-100, and 100-200 m) were sampled. Replicate tows at each depth comprised a sampling series. To sample at discrete depths without contamination by animals from shallower depths, the trawl was lowered with the first net open, and the second net was opened for the desired sampling time and then closed, and the trawl was retrieved with the third net open. To sample the two shallower strata, the trawl was lowered to 50 m, the second net was opened at that depth, and then the third net was opened at 25 m to sample the shallow stratum. For the two deeper strata, the second net was closed at the upper end of each stratum, and the trawl was retrieved with the third net open. Thus, a full set of duplicate samples for each depth stratum required six deployments of the trawl. The summer cruise had two series of night sampling (9-10 and 28-29 July) and one of day sampling (14-15 July); the winter cruise had one series of day and night sampling (4-10 February 1985). Each net was fished for 18 minutes and tows were conducted in a stepped oblique fashion, in an attempt to sample depths equally within each stratum. The volume of water filtered was estimated with calibrated General Oceanics flowmeters mounted in the center of each net. Plankton samples were preserved at sea in a 4% buffered formaldehyde seawater mixture. In the laboratory, plankton volume was determined from a known total volume minus the remaining water volume after the plankton were strained (Omori and Ikeda 1984); gelatinous plankton and fishes larger than approximately 50 mm were removed before the volume was determined. Whole samples were sorted for fish eggs, larvae, and squid para larvae under a dissecting microscope. Larval fishes were identified to the lowest possible taxonomic level by Bruce Mundy.

This database contains ichthyoplankton data collected as part of the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program and other cruises that were designed to assess the status coastal pelagic species and the California Current ecosystem from 1951 to present. The primary data are eggs and larvae captured in ring or bongo nets (oblique tows), Calvet or pairovet nets (vertical tows), and manta nets (surface tows).
