* » Abstract |
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. |
