NCCA 2010 Ecological Fish collection Metadata for Assessed and Not_Assessed files. “’Assessed’ data were used to develop the Good, Fair and Poor ratings in the report. ‘Not_Assessed’ data were not used to develop the ratings.” "For questions about these data, please contact Hugh Sullivan at sullivan.hugh@epa.gov or use the Contact Us link on the webpage: http://www.epa.gov/national-aquatic-resource-surveys/forms/national-aquatic-resource-surveys-contact-us" "It is the responsibility of the end data user to become familiar with the QA codes used in the NCCA 2010 assessment (NCCA_QA_Codes.csv) and review the ""QA_CODES"" column in each dataset to determine whether the data meet quality objectives for specific uses." Location information for each site is contained in the SITEINFO File. Use UID as key column for merging data. Ecological Fish Collection Info Metadata Variable Definition UID Unique identifier for the site/visit SCIENTIFIC_NAME Genus and species of specimens submitted for Ecological Fish Tissue Contaminant Analysis COLLECTION_DATE Date specimen was collected COLLECTION_SUCCESS? "Was specimen collected? Legal Values are ""YES"" or ""NO""" MEET_SIZE_REQ? "Did the specimens in the composite meet the size requirements: 1) > 100 mm in length; 2) Smallest specimen was no smaller than 75% of length of longest specimen. Legal Values are ""Y"" or ""N""" TARGET_SPECIES? "Were specimens submitted in the target species list? Legal Values are ""Y"" or ""N""" SAMPLE_ID "NCCA Assigned sample identificaiton numbers. All fish from the same composite will have the same 6 digits to the left of the decimal point. Each specimen within the composite will have sequential numbers to the right of the decimal point, beginning with "".01""" TTL_LENGTH(mm) total length of fish. COMMENT additional collection comments as necessary. "Note: because this is an ECOLOGICAL fish tissue contamination assessment, as long as there was enough composited fish tissue to analyze, composites were analyzed for tissue contaminants whether or not they met the target species or size requirements." Genus of Specimen Type of sediment grab apparatus used to collect sample Surface area of grab apparatus Number of grabs composited to make up sample "Surface area of grab apparatus. When grabs are composited, surface area consists of sum of grab areas from each grab in composite." Depth grab penetrated into substrate Size of openings in screen through which benthic samples was sieved in the field before shipment to taxonomic laboratory QA codes associated with grab used to obtain sample Comment to accompany QA Code if necessary
