Life history data were collected from Atlantic sharpnose and blacknose sharks during the Congressional Supplemental Program during 2011. Data collected include length, sex, state of maturity and fecundity. Additionally, reproductive tracts were removed and measures of anatomical structures were obtained.

This data represents the catch and size characteristics of fish parts that were collected for life history studies.

This data includes life history estimates (e.g. length-at-age, maturity status) generated by PIFSC LHP. Included in this data set are samples from fishery dependent and independent sources. The regions covered in the data set are from the North and South Pacific Ocean including the Hawaiian, Samoan, and Marianas Archipelagos. It contains the information used in LHP completed studies.

Reproductive data from Atlantic sharpnose sharks were collected from specimens captured throughout the northern Gulf of Mexico on various research vessels. Data included those necessary to describe the size at maturity, reproductive cycle, mating period, gestation time and fecundity of the species.

The main market sampling program in the Commonwealth of the Northern Mariana Islands (CNMI) is the new biosampling program implemented in late 2010 on the island of Saipan. It is a joint Division of Fish and Wildlife (DFW) and industry project with a local environmental consulting firm doing most of the field work, data processing, and obtaining of life history samples. DFW is working up some of the life history samples for that aspect of the project. It is strictly a voluntary data collection system requiring ingenuity to obtain the participation of a large percentage of the main fish vendors on the islands of Saipan, Rota and Tinian. All catches are from the CNMI with some of them coming from up to 100 miles from Saipan. It is a census sampling program of 100% of the commercial harvest of a subsample of the trips landing during any sampling period. Due to logistics and resource limitations, the majority of sampling was initially (Dec 2010-late 2012) focused on the spearfish reef fish fishery on Saipan. This has since expanded to include information on the bottomfish fishery as well data from Tinian and Rota. Life history samples are also being collected on several species on reef fish and one deep bottomfish. These data are considered confidential.

Data from fish captured by Erwin, Casey 1988. Includes fish size, weight, sex, reproductive stage data as well as quantitative stomach contents data and qualitative position data. Approximate locations where fish were caught are provided in the database. Additionally an approximate image map is also provided as a visual reference. These data are stored in an Access Database. Additionally, another Microsoft Access database containing data from this cruise, plus several others is available for download from the URL given below.

A reassessment of the diet of the Atlantic sharpnose shark Rhizoprionodon terraenovae was conducted to provide an update on their trophic level (n390). Rhizoprionodon terraenovae primarily consume teleost fish however, loggerhead sea turtles Caretta caretta were also found in the diet for the first reported time. Analysis suggests that calculated trophic level may significantly depend on geographic area, thus adding a new factor to fishery management decisions.

Coastal shark community structure was quantified across 10 geographic areas in the northeastern Gulf of Mexico using fishery-independent gillnet data from 2003-2011. A total of 3,205 sets were made in which 14,244 carcharhiniform sharks, primarily juveniles, were caught comprising 11 species from three families. Atlantic sharpnose sharks (Rhizoprionodon terraenovae) were the most abundant species overall followed by bonnethead (Sphyrna tiburo) and blacktip sharks (Carcharhinus limbatus). Two-way crossed analysis of similarity (ANOSIM) found geographic area to significantly influence shark species-life stage assemblages while season did not. Resemblance matrices between environmental data and shark community assemblage found the two were significantly correlated with the combination of salinity and turbidity producing the highest spearman rank correlation value. Species diversity varied by geographic area, but was generally highest in areas with the greatest amount of fresh and saltwater fluctuations. The mean size of the three most abundant species differed across geographic areas whereas, those species in lower abundances also differed across regions, but exhibited no discernible pattern. Our results suggest geographic area is important for juvenile sharks and some areas may be considered important nursery areas for many species. Atlantic sharpnose and blacktip shark were not restricted to any specific geographic area but species such as bull (C. leucas), spinner (C. brevipinna), blacknose (C. acronotus), finetooth (C. isodon), sandbar (C. plumbeus) and scalloped hammerhead (S. lewini) sharks were only consistently captured within a single area or over a select group of areas.

These data characterize treatments and outcomes in laboratory-based ocean acidification experiments conducted that the NOAA NEFSC Howard Laboratory. Experiments vary by species used, scope of study (experiment duration and species’ life-stages examined), and experimental design including number of treatments, levels, and replicates, and the suite of response variables. This experiment used summer flounder (Paralichthys dentatus) as subjects, one treatment (concentration of aqueous pCO2), three treatment levels (775, 1808, and 4714 uatm pCO2, pHs of 7.8, 7.5, and 7.1, respectively), three replicates (replicated downstream from each unique CO2 source), and the following response variables: survival of embryos to hatching and of larvae to age 28 d post-hatching; size, shape, and image-based developmental features of larvae; and histopathologically determined status of key organs (eye, heart, liver, gall bladder, gastro-intestinal tract, epidermis, kidney, spinal cord, and muscles) and cranio-facial and skeletal elements.
