Fish Abundance Surveys
Project
Completed
2013-09-09
The Alaska Fisheries Science Center's Status of Stocks and Multispecies Assessment (SSMA) Programs Fishery Interaction Team (FIT) conducted a fish survey in the marine offshore waters of the Beaufort Sea during the month of August, 2008. The Mineral Management Service (MMS) provided funding for the survey. The results of the survey provided estimates of abundance, species composition and biological information of marine fish and invertebrates, oceanographic properties and information on the macro- and micro- zooplankton communities.
To quantify the distribution, abundance, and biological condition of important offshore marine fish species. To assess the biology, behavior, and dynamics of key ecosystem components for ongoing scientific research. Based on results of the survey, recommend methods for future monitoring that could provide time-series and data trend information necessary to support offshore development decisions and serve as a proto-type fisheries component of future MMS or other ocean observing systems.

This is where the catch information for the bottom trawls is stored. There are a few hauls that appear in "tblBotHaul" that do not appear in the "tblBotCatch" table which means no catch was associated with that haul, either due to gear loss or damage. This table should be examined with the "tblBotHaul" so the reader is aware of gear type differences and gear performance codes (under "comments" in "tblBotHaul") associated with all the bottom catches. In particular, haul 3 was very large and highly diverse. In addition to collecting a random "subsample", we "subsampled" the "subsample". For example for the fish species Boreogadus saida (Arctic cod) in haul 3, the number of fish listed in the "SubSampleNumber" field is 5,163. This number was extrapolated from a "subsample" of a "subsample". Situations in which high counts appear (greater than 300) in the "SubSampleNumbers" field implies that is an extrapolated number from a "subsample" of a "subsample", which is most common for invertebrate species (only appears in haul 3 for Arctic cod). The remaining data entries that appear in the fields "SubSampleWeight" and "SubSampleNumbers" are actual counts and weights from randomly selected subsamples of the entire catch. Also the reader should note that if a species did not appear in a particular haul, it does not appear in this table. This important in estimating fish abundance and densities, we did NOT record zero catches in this table; however when estimating biomass, zero catches of a species SHOULD be included. NOTE: All invertebrate data is preliminary. The vouchered invertebrate specimens (excluding crab) are currently being published as of September, 2013.

All methods of data collection and recording in this table followed the Alaska Fisheries Science Centers RACE Division protocols (Stauffer 2004). The field "AreaSweptkm2" is often used to calculate biomass. This table links to the other 3 tables called: "tblBotCatch" (for fish catches), "tblBotLength" (for fish lengths collected), and "tblBotSpecimen" (for fish specimen collections e.g., age, gonads etc.). Note: the field "NetType" is the only field that informs the reader which hauls used each of the 2 gear types. See the Final Report for differences in catches due to gear type.

tblBotCatch
This is where the catch information for the bottom trawls is stored. There are a few hauls that appear in "tblBotHaul" that do not appear in the "tblBotCatch" table which means no catch was associated with that haul, either due to gear loss or damage. This table should be examined with the "tblBotHaul" so the reader is aware of gear type differences and gear performance codes (under "comments" in "tblBotHaul") associated with all the bottom catches. In particular, haul 3 was very large and highly diverse. In addition to collecting a random "subsample", we "subsampled" the "subsample". For example for the fish species Boreogadus saida (Arctic cod) in haul 3, the number of fish listed in the "SubSampleNumber" field is 5,163. This number was extrapolated from a "subsample" of a "subsample". Situations in which high counts appear (greater than 300) in the "SubSampleNumbers" field implies that is an extrapolated number from a "subsample" of a "subsample", which is most common for invertebrate species (only appears in haul 3 for Arctic cod). The remaining data entries that appear in the fields "SubSampleWeight" and "SubSampleNumbers" are actual counts and weights from randomly selected subsamples of the entire catch. Also the reader should note that if a species did not appear in a particular haul, it does not appear in this table. This important in estimating fish abundance and densities, we did NOT record zero catches in this table; however when estimating biomass, zero catches of a species SHOULD be included. NOTE: All invertebrate data is preliminary. The vouchered invertebrate specimens (excluding crab) are currently being published as of September, 2013.
