This dataset includes vertical distribution of ichthyoplankton data collected from DOLPHIN and DELAWARE II in the Middle Atlantic Bight in 1965-66 and 1972-75, part of a larger collection of data collected for Bureau of Land Management. Data has been processed by NODC to the NODC standard Zooplankton (F124) format. The F124 format is used for data from sampling and analysis of marine zooplankton. Information on zooplankton abundance, distribution, and productivity derived from these data support studies of marine populations and ecosystems. Data reported may include: cruise information, position, date, and time of sampling; bottom depth, sampling depths, temperature, and salinity; gear type, volume of water filtered, total dry and wet weight, and other data for total haul; and data for subsamples by species. Data on zooplankton catch by species may include subsample size, zooplankton concentration, life history code, and numbers of adults, juveniles, eggs, and larvae. Estimated density of holoplankton and meroplankton and data on ichthyoplankton may also be reported. A text record is available for comments. Note: there are two options for reporting subsample counts of individuals at different life history stages. If life history codes are used, only number of adults should be reported on that record. Additional separate records should then be used to report number of juveniles and so on. Alternatively, life history codes may not be used and number of adults, juveniles, and so entered in the proper fields of a single record.

This dataset includes data from the CalCOFI ichthyoplankton database and data from publicly available ERDDAP servers hosted at Southwest Fisheries Science Center. The data include fish species occurrence and distribution, identification and developmental staging of fish and egg stages as well as information about cruises, instruments and platforms used in the CalCOFI program from 1951-10-01 to 2017-04-22. The ERDDAP data is available in CSV format. The raw files were extracted from the SWFSC CalCOFI database and includes documentation that explains each table and how to reconstruct the database schema.

Ichthyoplankton (biological) data from cruise 0701 from the Yucatan Peninsula, Mexico, Belize, and South Florida. Data is housed in a spreadsheet database (Excel) format for use of members of the Early Life History (ELH) group.

A stratified random grid survey of five areas in the Gulf of Carpentaria was carried out in June 1990 using demersal fish trawls with a 100mm codend on a commercial trawler. Lutjanids and other large commercial finfish were surveyed.

The Pre-recruit survey project is collaborative involving researchers from the FE Division based in 3 laboratories (Newport, Seattle and Hammond), scientists from the Southwest Fisheries Science Center (Santa Cruz), along with researchers from several universities (Oregon State University, University of Oregon, University of Washington, University of California, Santa Cruz). In concert with a similar SWFSC survey effort through California, the purpose of this project is to conduct annual surveys within the coastal ecosystem off Oregon and Washington to quantify the environmental conditions and biota found along the California Current and to elucidate ecosystem-level processes affecting managed and protected marine resources. This project currently supports three main efforts: 1. An annual sampling regime of the hydrology, plankton, small fish, and predators along transects over the Continental Shelf from Oregon and Washington. This consistent survey has generated significant information on within- and between-year variability in the California Current Marine Ecosystem and has yielded valuable insights into the food web off our coast. 2. Collection of specimens for diet analysis, growth, containment load, and other studies related to the ecology and production of commercially important taxa and their relationships within the food web. 3. Parameters and ecological processes quantified during this effort are used in forecasts involving species, assemblages, and ecosystems and also to parameterize ecosystem models used to evaluate cumulative risks and managerial strategies. We towed a 71 cm diameter Bongo net at each trawl station from 100 m to the surface.
