Fish Remains NISP Analysis
The data files NISP-PECES.TXT and NISP-PECES.XLS provide the counts of fish remains for the four excavated units (6A, 6B, 8 and 9) by Stratigraphic Unit (S.U.). The remains were identified at the species (in italics) and family (in upper case) levels. Only diagnostic bones like otoliths, head bones, and vertebrae were used to identify the taxa. After the taxa were identified, the abundance of each taxon was calculated by the number of identifiable specimens (NISP). NISP-PECES.TXT is a comma delimited ASCII text file, while NISP-PECES.XLS contains the same data in the form of an Excel spreadsheet. Each line in the ASCII file corresponds to a unique stratigraphic unit (S.U.). There are 573 lines, each with 27 variables separated by commas. The variables are listed in the following order:
| 1 |
Stratigraphic Unit (S.U.). A natural or cultural layer or feature, sequentially numbered within an excavation unit, where the alphanumeric part to the left of the period identifies the unit, and the digits to the right of the period identify the layer or feature.

The first line of the ASCII text file, for example, looks like this:
6A.2,,,1,,,12,,8,,,,5,1,,,,1,,,,,,,,,28
Which means that the fish remains came from S.U. 6A.2. One NISP of jurel (jack mackerel; Family: CARANGIDAE; Genus species: Trachurus murphyi), 12 NISP of sardina (sardine; Family: CLUPEIDAE; Genus species: Sardinops sagax), 8 NISP of anchoveta (anchovy; Family: ENGRAULIDAE; Genus species: Engraulis ringens), 5 NISP of lorna (drum; Family: SCIAENIDAE; Genus species: Sciaena deliciosa), 1 NISP of corvina (drum; Family: SCIAENIDAE; Genus species: Cilus gilberti), and 1 NISP of burro (arnillo drum; Family: SCIAENIDAE; Genus species: Cheilotrema fasciatum) were found. A total of 28 NISP counts were collected in this S.U.
The last, or 573rd line of the ASCII text file is:
9.46,,,,,,2,,18,,,,,,,,,,,,,,,,,,20
Which means that the fish remains came from S.U. 9.46. Two NISP of sardina (sardine; Family: CLUPEIDAE; Genus species: Sardinops sagax) and 18 NISP of anchoveta (anchovy; Family: ENGRAULIDAE; Genus species: Engraulis ringens) were found. A total of 20 NISP counts were collected in this S.U.
