Stomach contents were tabulated for 734 swordfish (Xiphias gladius) from the central North Pacific from 1989 to 2000 (most from 1994-1998). The swordfish were captured by various commercial fishermen (with stomachs collected by the Pacific Islands Region Observer Program) or during PIFSC research cruises. Prey items from the stomachs were identified to the lowest taxonomic rank possible, enumerated, weighed, and measured, primarily by Bruce Mundy, Michael Seki, Happy Williams, Alan Everson, with assistance from Fisheries Observers from the Pacific Islands Regional Office. Associated data on fish length, weight, collection year, month, and location were obtained from observer, fishermen, or cruise data records, or from whole fish brought to the laboratory.

Standard length only or standard length and fork length of juvenile tunas were measured during NOAA Research Vessel Townsend Cromwell Cruise 032 (12 July - 4 October 1967). Fish were caught using a new small-mesh midwater trawl. Date/time and location data from RB004AA1 were imported into the data.

Number of juvenile tunas and other species were counted for fish caught using a new small-mesh midwater trawl that was deployed during NOAA Research Vessel Townsend Cromwell Cruise 032 (12 July - 4 October). Counts for fish caught at station numbers 60 to 85 are provided in this dataset. Date/time and location data from RB004AA1 were imported into the data.

This data set contains tuna morphometric measurements collected by Pacific Oceanic Fishery Investigations from 1949 through 1957 on research vessels. Date, position, gear, sex and maturity, weight and length measurements were collected on the following species: skipjack tuna, little tunny (kawakawa), bigeye tuna, yellowfin tuna, and albacore.

Four cruises aboard the NOAA ship Townsend Cromwell were conducted, collectors included George Boehlert and Bruce Mundy. Two transects, oriented in an east-west direction, were established, one each on the leeward and the windward sides of the island. Stations were located 1.8, 9.3, and 27.8 km from shore along the leeward side and 3.7, 9.3, and 27.8 km from shore along the windward side. Larvae were sampled below the surface with a 1 m2 multiple opening-closing net and environmental sensing system (MOCNESS) and at the sea surface with a 0.49 m2 Manta net modified to take surface samples to a depth of 0.7 m. All nets were constructed of 0.333 mm Nitex mesh. Estimates of water volumes filtered by both gear types were based on mechanical flowmeter readings. Samples were taken in eight depth strata (neuston, 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, and 60-80 m) at each nearshore station and in nine depth strata (neuston, 0-20, 20-40, 40-60, 60-80, 80-100, 100-120, 120-160, and 160-200 m) at the 4 offshore stations. MOCNESS hauls were 12 minutes duration for each net (stratum), fished in a stepped oblique fashion from deep to shallow with mean tow speeds of approximately 75 cm/sec; the tow speed was adjusted to maintain a net mouth angle near 45". Neuston tows were 24 minutes, taken during the mid-point of the MOCNESS tows. Replicate tows were taken at each station in both day and night, but only the first replicate sample was sorted for the December, April, and June cruises, whereas both replicates were processed for the September cruise. All fish larvae were identified to the lowest taxonomic level possible by Bruce C. Mundy. Squid paralarvae were transferred to the Dr. Richard Young (Dept. of Oceanography, Univ. of Hawai'i). Other taxa were not routinely sorted, but heteropods from selected samples have been transferred to Dr. Roger Seapy (Dept. of Biological Sciences, California State Univ. Fullerton; see Seapy 1990. Patterns of vertical distribution in epipelagic heteropod molluscs off Hawaii. Mar. Eco1.-Prog. Ser., 60: 235-246.) and numbers of four species of copepods were obtained from subsamples from certain stations by Dr. R. Patrick Hassett (Dept. of Zoology, Arizona State Univ.; see Hassett and Boehlert 1995. Seasonal, vertical and horizontal distributions of four species of copepods around Oahu, Hawaii: data report. NOAA Tech. Memo. NMFS, NOAA-TM-NMFS-SWFSC-215, 21 p.). In 2023, Andrea Schmidt (andrea.schmidt@noaa.gov) provided: 1) RB008AA1_V_LAT_LONG_MEANS_V - Latitude and longitude from cruise reports and MOCNESS sensor data were inserted into RB008AA1_V data. 2) RB008AA1_UKUSIZES_V - A dataset with larval measurements for uku, Aprion virescens. Methodology: We processed larval uku from a backlog of existing partially processed wet-archived ichthyoplankton samples from O'ahu that were likely to contain larval uku and enhance available record data. We identified and measured uku larvae from ichthyoplankton samples collected around the island of O'ahu on cruises TC8504 (September 6-15, 1985) and TC8604 (June 24-July 2, 1986). These cruises were part of a yearlong series of quarterly surveys described in Boehlert and Mundy (1996). Every three months a series of MOCNESS tows were conducted at 1.8, 9.3, and 27.8 km from shore during the day and the night. Two replicates were collected for each station, but not all replicates were processed. Since the entirety of these samples were archived and stored at PIFSC, we processed the second replicate for TC8604 and measure all previously identified uku from TC8504. These were the only depth integrated samples for which we could generate length data along a gradient from shore. Examination occurred under an EVOCAM2 scope (Vision Engineering Ltd, United Kingdom) and measurements of larval standard length were conducted with the ViPlus software (Vision Engineering Ltd, United Kingdom). The first replicates of the Boehlert and Mundy (1996) dataset were used to review Lutjanidae

This data set contains tuna morphometric measurements collected by Pacific Oceanic Fishery Investigations from commercial fishery (chartered) vessels in 1952 and 1955. Date, position, gear, sex and maturity, weight and length measurements were collected on the following species: skipjack tuna, bigeye tuna and yellowfin tuna.

Natural-resource professionals performed novel research on the reproductive biology of exploited reef fishes. Each participant produced reproductive data for a single target species, yielding new information for four species. These data can be used to describe: length-weight relationships (including sex-based differences), size-at-maturity for each sex (minimum size-at-maturity, and size-at-50%-maturity), reproductive mode (total vs batch spawning, gonochorism vs hermaphroditism), sex ratios (overall and size-specific), length-fecundity relationships, and reproductive periodicity (lunar, seasonal). The fish were taken in the coral reef ecosystem for the area west and south of Kavieng, New Ireland Province, Papua New Guinea in March 2015. Specific site location of each catch was not given. About 90% of the catch was near Mait Island.

The densities of juvenile Acanthaster planci (Crown-of thorns starfish) were sampled at 16 inner mid-shelf reefs of the central Great Barrier Reef during trips in July, September and November 1986 and were resurveyed in November/December 1987. The reefs sampled were: Lodestone, Keeper, Little Broadhurst, Bowden, Mid, Stanley (3 independent surveys), Old, Charity, Hope, Showers, Bait, Ross, Square, Robertson, Credlin and Bushy-Redbill.A destructive sampling technique was chosen due to the small size and cryptic behaviour of the starfish during their first 10-12 months of benthic development. On each reef two replicate 10x1m transects were sampled at each of two arbitrarily chosen sites located within three depth zones (reef base, reef crest and reef flat) and two exposure categories (windward and leeward). Surface features of each transect were mapped with a resolution of 15cm. Loose and detachable pieces of substrate were removed, broken into small pieces and searched underwater for the presence of stafish. While the study was primarily focused on Acanthaster planci, all starfish species were recorded. The position of each starfish encountered was recorded on the substratum map and the specimen retained for subsequent identification and measurement. Sampling of a transect ceased either when it reached bed rock or a depth of 30cm.In order to determine the precision of the sampling method, the reef with the highest densities observed on the first cruise in 1986 (Stanley Reef) was resurveyed twice more during subsequent cruises that year.In both 1986 and 1987, transects at one leeward site on each of four reefs were sampled nocturnally. Twelve 12 transects were marked out and 6 were sampled in the usual way during the day and 6 were searched without destruction after 2100 hours. This research was undertaken to:1. define the juvenile habitat of Acanthaster planci and 2. investigate the spatial and temporal abundance of juveniles and their contribution to the population outbreaks observed in this species.

These data sets contain raw and processed data to compare life history demographic information necessary to manage spotted seatrout in NW Florida. Specific objectives were to develop estuary-specific information on age growth, mortality rates, spawning seasonality, age size at maturity, and age size composition of the recreational fishery for Apalachicola, St. Joseph, St. Andrew, Choctawhatchee, Pensacola, and Perdido Bay systems.

Compilation of all samples collected from striped marlin (Tetrapturus audax) collected and brought to the Aiea Heights Research Facility by the PIRO Hawaii Longline Observer Program (LOP) for age and growth and size at maturity research.
