LENGTH

Numeric field to identify the lower bound of the length group to which a fish record belongs. A length group is defined as all fish of a particular species for a collection which fall within the GRP WIDTH (group width) range. See the GRP WIDTH description.

T F S

Alphabetic code to identify system used for length measurement: Following are valid codes:

T or Blank = Maximum total length measurement; distance from anterior-most extreme of head (jaw closed) to most distant lobe of caudal fin (lobes compressed to achieve maximum length)

F = Fork length; distance from anterior-most extreme of head (jaw closed) to fork of caudal fin (tip of median fin rays)

S = Standard length; distance from anterior-most extreme of head (jaw closed) to caudal peduncle (posterior margin of hypural bone)

GRP WIDTH (Group Width)

Numeric field to record the range in centimeters of a a length group from within which fish were enumerated or bulk- weighed. For example, if LENGTH is 40 and GRP WIDTH is 1, then the range of lengths for the fish representing this fish record would be from 40 through 49 millimeters. This field should be blank for fish that are unmeasured or individually measured to the nearest 1 millimeter.

FISH COUNT

Numeric field to record counts of fish represented by the row of data. Fish Count is 1 for all individually measured lengths and weights and 1 for bulk counts. For example, if a particular fish was measured to the nearest 1 millimeter, then Fish Count is 1. If just one fish of a particular length group is encountered during length group enumeration, then Fish Count is also 1 for that length group. However, if 10 fish of a length group are encountered during group enumeration, then Fish Count is 10 .

IND/AGG. WEIGHT

Numeric field to record individual or aggregate weights (in grams). Aggregate weights are distinguished by the presence of a Group Width value. Weights are measured only for special purposes.

PATHOLOGY CODE

Represents LTRMP fish health/pathogen codes as follows:

0 or blank = No visible abnormality

1 = Parasite

2 = Skeletal abnormality

3 = Tumors

4 = Injury

5 = Skin/fin/eye

6 = Other

SUBPROJECT CODE

Two byte length alphanumeric field containing information needed to interpret data in USER DEFINED FIELDS. Codes for each byte are as follows:

Byte 1:

1 = Aging structures (otoliths, scales, etc.) collected, specimen bar code

2 = Stomach contents collected

3 = Both aging structures and stomach contents collected

0 = Continued from previous line Note: When the above codes are used, the specimen bar code number should be recorded in bytes 1-10 of USER DEFINED FIELDS.

Byte 2:

0 = Tag implanted, number follows in bytes 1-11 of USER DEFINED FIELDS, fish released

1 = Tag recovered, number follows in bytes 1-11 of USER DEFINED FIELDS, fish released

2 = Tag recovered, number follows in bytes 1-11 of USER DEFINED FIELDS, fish not released

3 = Tag scar visible, fish released

4 = Tag scar visible, fish not released

5 = Fin clipped, fin position follows in byte 14 of USER DEFINED FIELDS

6 = Fin clip recovered, position follows in byte 14 of USER DEFINED FIELDS, released

7 = Fin clip recovered, position follows in byte 14 of USER DEFINED FIELDS, not released

USER DEFINED FIELDS

Twelve byte length alphanumeric field containing special information not routinely collected during standardized monitoring activities. Following is a description of what these twelve bytes represent.

Bytes 1-10: Specimen number (aging structure and/or stomach contents).

Byte 11: Fin clipping position.

-- or --

Bytes 1-11: Tag number.

Byte 12: Gill net mesh size code as follows:

1 = 4"

2 = 6"

3 = 8"

4 = 10"

-- or --

Byte 12: Number of seines or trawls

RECORDER CODE

Alphanumeric field to identify the LTRMP recorder responsible for recording of this measurement sheet data. These codes are permanently assigned to LTRMP staff at each station.

NUMBER FISH ON SHEET

Numeric field to record the total number of fish (sum of Fish Counts) recorded on this Fish Measurement Sheet.

ENTRY OPERATOR (MEASUREMENT SHEET)

Alphanumeric field to identify the operator responsible for entering (keying) the data from the measurement data sheets into an electronic format.

VERIFY OPERATOR (MEASUREMENT SHEET

Alphanumeric field to identify the operator responsible for verifying the electronic keyed data from the measurement data sheets.

ORPHAN FLAG

Administrative field used to identify fish detail records missing a corresponding collection (header) record.

BATCH NUMBER

Administrative field used to track keyed data batches.
