Fishery-independent data are provided for use by government agencies, recreational and commercial fisheries, researchers, and others. The intent of the NEAMAP program is to provide coordination among existing fishery-independent surveys to optimize activities, promote comprehensive and consistent data collection, and maximize the usefulness of survey data. The governing board of NEAMAP is the Operations Committee, which helps design of surveys and ensure their long-term operation and ensures communication between state agencies and the ASMFC policy board.

NEAMAP surveys are conducted by NEAMAP partners; they include both partner and Operations Committee designed surveys, and operate on local and regional spatial scales. NEAMAP surveys are designed to collect long-term fishery-independent data on species abundance, distributions, and life history, as well as related ecosystem and environmental information. NEAMAP surveys are reviewed and approved by the NEAMAP Operations Committee.

A fishery-independent bottom trawl survey designed to sample fishes and invertebrates from coastal waters in depths of 20-90 feet between Aquinnah, Massachusetts and Cape Hatteras, North Carolina. The main objective of the survey is the estimation of biomass, length and age structures, and diet compositions of finfishes and select invertebrates inhabiting the area. The survey began in 2007 and is conducted aboard the F/V Darana R and led by the Virginia Institute of Marine Science.

The Massachusetts trawl survey is conducted every spring and fall since 1978 to monitor distribution, abundance, and size composition of fish populations in Massachusetts state waters. All species of finfish and select invertebrates are weighed and measured. A subset of species are sampled for sex, maturity, and age structures. The survey follows a random stratified (by depth) design with a station density of approximately 1 station/19 nmi². The survey is conducted aboard the R/V Gloria Michelle and operated by NOAA Corps officers.

The Maine-New Hampshire Inshore Trawl Survey is a resource assessment survey performed along the coastal waters of Maine and New Hampshire. Spring and fall surveys began in the fall of 2000 and are conducted aboard the F/V Robert Michael. The boat owner, captain, and crew have been actively involved in the survey’s design and implementation.

Since 1982, SEAMAP-SA has sponsored long-term standardized surveys that have become the backbone of fisheries and habitat management for its three regions—the South Atlantic, Gulf of Mexico, and Caribbean. SEAMAP-SA surveys collect data on the abundance and distribution of a variety of important commercial and recreational species (e.g., red drum, Atlantic croaker, shrimp, coastal sharks) from North Carolina to Florida. The SEAMAP-SA Database is a centralized database that houses SEAMAP-SA affiliated data. SEAMAP-SA is governed by the South Atlantic Committee, which consists of representatives from North Carolina, South Carolina, and Georgia, who are tasked with ensuring the smooth operations of existing surveys and consistency between surveys as well as designing new surveys.

The objective of the SEAMAP-SA Reef Fish Survey is to collect and provide abundance and life-history information on reef fish species for use in stock assessments, research, and management decisions. The SEAMAP-SA Reef Fish Survey is coordinated with Marine Resources Monitoring, Assessment and Prediction (MARMAP) and the Southeast Fisheries Independent Survey (SEFIS) sampling efforts, collectively referred to as the Southeast Reef Fish Survey (SERFS). MARMAP has conducted fishery‐independent research on the continental shelf and shelf edge between Cape Hatteras, North Carolina, and St. Lucie, Florida, for over 40 years and is housed at the Marine Resources Research Institute (MRRI) of the South Carolina Department of Natural Resources (SCDNR). In 2008, SEAMAP-SA started to provide funding to complement the MARMAP program. The main gear types used are chevron traps, short bottom longline, and rod and reel; oceanographic variables (mostly temperature, salinity, and depth) are also measured using a CTD.

The SEAMAP-SA Coastal Survey is conducted by the Marine Resources Division of the South Carolina Department of Natural Resources. Since its inception in 1986, the survey has provided long-term, fishery-independent data on seasonal abundance and biomass of numerous species, including bony fishes, sharks and rays, crustaceans, and cephalopods. In recent years, the survey has also begun collecting data on sea turtles and horseshoe crabs. The sampling area includes the coastal zone of the South Atlantic Bight from Cape Hatteras, North Carolina, to Cape Canaveral, Florida.

The North Carolina Pamlico Sound Survey is a USFWS Sport Fishing Restoration funded fishery-independent trawl survey conducted by the North Carolina Division of Marine Fisheries since 1987. As a program component of the SEAMAP-South Atlantic, the survey was designed to provide long-term fishery-independent data on the distribution, relative abundance, and size composition of estuarine fish and decapod crustaceans for the waters of the Pamlico Sound and associated rivers and bays.

The objective of the SEAMAP-SA longline surveys is to conduct a multi-species survey in the Southeast region. Target species are adult red drum and coastal sharks. The program consists of three separate state-run surveys in North Carolina, South Carolina, and Georgia. Samples from adult red drum (otoliths, reproductive tissues, and genetic samples) as well as coastal sharks (genetics, life history, guts and muscle) are collected and processed to describe populations in the Southeast. In 2008, the SEAMAP-SA began supporting bottom longline surveys of the adult red drum population from North Carolina to Florida to develop a better understanding of abundance, distribution, and age composition of the stock and to provide a fishery-independent index of adult red drum abundance. The objectives were later expanded to include gathering abundance, distribution, age composition, and life history information on coastal shark species caught in the surveys. Many red drum and coastal sharks encountered in the surveys are tagged to provide information on survival rates, migratory behavior, and stock identification. Information is also collected on the presence of hatchery-origin fish in the offshore adult red drum population, as well as sex ratios, maturity, and age structure of the population. All of this information is critical for evaluating the status of the red drum population, especially the adult portion, and developing a successful red drum management program. Information derived from the surveys is also useful for coastal shark assessments in the South Atlantic.

The horseshoe crab trawl survey, conducted by Virginia Tech since 2002, is the only survey designed to sample the horseshoe crab population in coastal waters. Its geographic scope is broad, covering the Atlantic coast from Atlantic City, New Jersey to Wachapreague, Virginia, and also the lower Delaware Bay. The survey area is stratified into nearshore and offshore areas and into trough and non-trough areas. All strata are randomly sampled. Relative abundance of immature and mature male and female crabs are tracked separately to inform the development of a stage- and sex-specific model in the most recent peer-reviewed stock assessment (2019).

Relative abundance data from the horseshoe crab trawl survey are a critical component of the Commission’s coastwide horseshoe crab stock assessment and the Adaptive Resource Management (ARM) framework, both of which were endorsed through independent peer reviews. The ARM framework includes modeling to link horseshoe crab harvest to multispecies objectives, particularly to demographic recovery of imperiled red knots and other shorebirds. The ARM was developed jointly by the Commission, U.S. Fish and Wildlife Service, and U.S. Geological Survey in recognition of the importance of horseshoe crab eggs to migratory shorebirds stopping over in the Delaware Bay Region.

Due to a collapse in the resource, the northern shrimp fishery has been under a fishery moratorium since 2014. Despite its name, the Gulf of Maine Northern Shrimp Trawl Survey provided valuable information for a number of other species as well, including alewife, Jonah crab, Atlantic herring, and monkfish.

The survey, which was conducted aboard the R/V Gloria Michelle, a 65-foot, 96 gross ton stern trawler, was discontinued in 2024 due to the cost of maintaining a survey focused on a depleted resource that has been under a 10-year fishery moratorium and shows little prospect for recovery, given the current environmental conditions in the Gulf of Maine.

Although several fishery-independent trawl surveys encounter lobster, trawls cannot operate on rocky or ledge habitats preferred by lobster. Also, trawl survey operations are challenging in areas where fixed gear (e.g., lobster pots and gillnets) is deployed. Therefore, a large portion of productive lobster habitat is not accessible to trawl survey gear. In contrast to trawl surveys, the Ventless Trap Survey was specifically designed to catch lobster using a more effective gear, the lobster trap. The Ventless Trap Survey is a collaborative, standardized monitoring effort designed and implemented starting in 2006 by the states of New York, Connecticut, Rhode Island, Massachusetts, New Hampshire, and Maine. New York and Connecticut discontinued sampling after 2009 due to lack of funding, while sampling has continued in the other states.

Commercial lobster traps are required to have an escape vent that allows most sublegal lobster to exit the trap. Escape vents reduce the stress and potential mortality associated with being trapped and processed on deck. The Ventless Trap Survey utilizes multiple sets of either six alternating ventless and vented traps or three ventless traps on a common line deployed in the same location, throughout each sampling season. The vented traps are designed to monitor trap catch rates of mostly legal-sized lobster. The ventless traps are designed to monitor catch rates of all lobster sizes, including sublegal lobster representing future recruitment to the fishery. Catch rates from both trap types can be compared to evaluate size selectivity of vented traps fished in the commercial fishery. The use of ventless traps improves estimation of abundance trends in small, sublegal lobster not yet recruited to the fishery.

Traps are deployed between June and November in a random stratified fashion such that sets of traps are placed at randomly selected seasonal sampling sites within different depth categories and geographic areas. The targeted soak time is three nights, but may vary depending on weather conditions. All lobster caught in the Ventless Trap Survey are examined and biological information is recorded, including carapace length, sex, egg-bearing status, shell disease condition, and v-notch status.

The Ventless Trap Survey data are used in lobster stock assessments as a fishery-independent index of abundance. The biological data collected provide additional vital information about changes in population length structure and sex ratio over time.
