Fish egg counts and standardized counts for eggs captured in CalCOFI icthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]). Surface tows are normally standardized to count per 1,000 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes only tows where one or more eggs were captured for the species selected by the user, i.e., no "zero" tows. The "Egg Counts" table includes all tows by species, i.e., both positive and negative tows.
The integrated modeling framework for Antarctic krill (Euphausia superba) has been extended to include estimates of krill growth consistent with survey data and to use multi-nation survey data collected from 1981 to 2014 near the Antarctic Peninsula. Four models of the population dynamics of Antarctic krill in Subarea 48.1 based on different aggregations of the data are described to illustrate the capabilities of the framework.
The California Current Cetacean and Ecosystem Assessment Survey (CalCurCEAS) is a marine mammal assessment survey of the U.S. West Coast waters. Similar research in this geographic area was conducted under the name of ORCAWALE (for Oregon, California, and Washington Line-transect Experiment) in previous years.
Pelagic eggs collected using the CUFES during cruises conducted by the SWFSC Fisheries Resources Division from 1996 to present. Data are typically collected every 30 min while the ship is underway. Eggs are identified as Pacific sardine, northern anchovy, jack mackerel, hake, squid, or other fish eggs. Some additional species identifications have been noted in the comments.
An aerial monitoring program was conducted during the period 1962 - 2007 in cooperation with aerial spotters working for the commercial purse seine fleet. Flights were conducted throughout the year to estimate abundance of pelagic fishes off California and Baja California, Mexico. Measurements were recorded for each identifiable species in 10'-longitude by 10'-latitude blocks. This file gives the legacy species codes assigned to each sighted fish group and their equivalent ITIS species codes. Each legacy species code may contain one and up to four species sighted in a group of fish spotted by the pilot in one block area during a flight.
In 1986 the U.S. National Marine Fisheries Service (NMFS) initiated a long-term, large-scale research program to monitor trends in the abundance of dolphin populations in the eastern tropical Pacific (ETP).
This is a collaborative research effort by an international team of scientists, including researchers from Southwest Fisheries Science Center (SWFSC) and research colleagues from Mexico, to improve methods to detect and estimate abundance of the critically endangered vaquita, or Gulf of California harbor porpoise.
The Hawaiian Islands Cetacean and Ecosystem Assessment Survey, called HICEAS, is a marine mammal assessment survey of the Exclusive Economic Zone (EEZ) of Hawaiian waters out to a distance of approximately 200 nautical miles. The 2010 survey was a collaborative research effort between NOAA Southwest Fisheries Science Center (SWFSC) and NOAA Pacific Islands Fisheries Science Center (PIFSC).
The Stenella Abundance Research Project (STAR) is a multi-year cetacean and ecosystem assessment study designed to assess the status of dolphin stocks which have been taken as incidental catch by the yellowfin tuna purse-seine fishery in the Eastern Tropical Pacific.
