SALMON_POPULATION_DETAILS

The total number of fish returning to spawn in the data collection year.

Comments or other helpful information about the observation of spawners in this viability computation.

The fraction of the total spawners that are the progeny of naturally-spawning fish.

A value between 0 and 1 that is the fraction of natural origin spawners. Natural origin spawners are spawners whose parents spawned in the wild. The fracWild is equal to one minus the fraction of first generation hatchery fish spawning in a given year. If all hatchery fish are marked, this value is the fraction of unmarked fish observed in a given year.

Comments or other information about the observed or estimated Hatchery fraction of the fish in this viability computation.

The number of additional wild fish that would have returned to spawn in a given year had there not been a catch (harvest).

The fraction of fish who are defined as having an age of 1 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 2 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 3 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 4 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 5 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 6 that returned to spawn in a given year.

The fraction of fish who are defined as having an age of 7 that returned to spawn in a given year.

Regime is an index of environmental conditions (usually intended as a measure of ocean survival) that should be entered as a decimal number centered on 1. It is used as a multiplier to adjust recruitment to average environmental conditions. When conditions are worse than average (regime < 1), recruits are adjusted upwards, when they are better than average (regime > 1), recruits are adjusted downwards.

Foreign key to the SALMON_POPULATION_GROUPS table to link SALMON_POPULATION_DETAILS records to a specific POPULATION_DB_ID using the SP_PKX primary key. This foreign key constraint is named SPG_SPD_FK.

Estimated total number of fish contributing to spawning in a particular year. Includes both natural origin and hatchery origin returns, adults and jack age classes.

Estimated number of natural origin (parents spawned in the wild) spawners contributing to spawning in a particular year. Includes both adults and jacks of natural origin.

Estimated number of adult spawners of natural origin in a particular year.

If available, estimate of the relative proportion of hatchery returns to the spawning ground that are jacks (i.e., age 3 fish for stream type chinook populations, age 2 fish for ocean type chinook populations).

The estimated proportion of adult returns removed by harvest in a particular run year. Assumes that all adult age classes are harvested at the same rate. Steelhead and yearling type chinook estimates reflect in-river fisheries. Snake River Fall chinook estimates also include an adjustment to incorporate an index of annual ocean impacts.

Fish of natural origin removed from the returning run for use as hatchery broodstock.

Total future adult returns produced from spawning in a particular brood year. Expressed as returns to the spawning grounds. For chinook, adult brood year returns from year n are calculated as the sum of age 4 returns in year(n+4), age 5 returns in year (n+5) and age 6 returns in year (n+6).

Total brood year returns proportionally adjusted to reflect an average annual smolt to adult return rate over a specified range of years. For Interior Columbia analyses, the average SARs are generally calculated for outmigration years 1980 to the most recent complete brood year (e.g., 2001).

If there is a certification process for these records, name of person who certified approval of the particular record.

If there is a certification process for these records, date that the particular record was approved or officially certified.

The username that loaded the record into the database. The username is dynamically captured by the database trigger when the record is inserted and saved to the database. This person may have no knowledge of content or meaning but ran the computer process that put the record into the database.

The date that the record was loaded into the database. This date is dynamically captured by the database trigger when the record is inserted and saved.

The name of the person who originated this record PRIOR to its being entered into the database. The name of the person to contact with administrative questions or an explanation of it content.

The date, or approximate date, that the person with content knowledge originated this record PRIOR to its being entered into the database.

If necessary, the date that the individual record becomes effective. Prior to this date the record is not valid.

If necessary, the date that the individual record ceases to be effective. To force a midnight expiration, this may be set by "Select to_date(to_char(sysdate +1 ,'mm/dd/yyyy')||' 23:59:59','mm/dd/yyyy hh24:mi:ss') from dual". After this date and time the record is not valid.

The username of the last person who modified this record. This username is dynamically captured by the database trigger any time the record is edited.

The last date that the particular record was modified. This date is dynamically captured by the database trigger any time the record is edited.

The number of times that the particular record was modified. This count is dynamically incremented by 1 by the database trigger each time the record is edited.

Flag whether or not this record has the "Deleted" status. Null means this record has NOT been deleted. "Y" means this record HAS been deleted. This flag allows "deleted" records to remain in the table for technical reasons. When the record is "Hard Deleted" it will be removed from this table and may or may not be placed in a historical table to preserve historical status.

If a set of User-Roles are developed for these records, this allows a particular Role (which may be a collection of other Roles) to be assigned to steward individual records. When any user attempts to modify a record, a database procedure will then dynamically examine the user's Role to determine if they are authorized to edit particular records.

The number of returning fish that were reared in a hatchery. Currently this data is not provided.

Indicates how age was estimated for a group of fish. Currently this data is not collected. Acceptable values: 1) If population-scale carcass sample size is = 20, apply the Annual Population Age Structure.

2) Else, if population-scale carcass sample size is = 19, apply the Annual Aggregate MPG Age Structure.

3) Else, if MPG-scale carcass sample size is = 19, apply the Long-Term (i.e.19601997) Population Average Age Structure.

Number of samples used in age structure determination.

Database-generated primary key (unique identifier) for each SALMON_POPULATION_DETAILS record, created by an internal sequence generator and used by the database to maintain referential integrity. This ID is not designed to be managed by users. This primary key constraint is named SALMON_POPULATION_DETAILS_PK.
