2012 Early Life History Experiment Data

2012 Early Life History Experiment Data

The goal of the experiment was to determine if incubation temperature effected fish growth and survival 31 days after feeding. The broodyear 2011 fish were placed into the experimental incubation treatments just after they had reached the eyed egg stage in late 2011. The eyed eggs and yolk sac fry were then either incubated in (6.5 degree C) or unchilled (9-10 degree C) water until they reached the swimup stage in early 2012. Although incubation temperature was the primary treatment variable of interest, the experimental design included the portion of the run when the eggs were spawned (= time when the eggs were place into the treatment) and hatchery source as secondary treatment variables of interest. The response variables of interest were average length in mm, weight in grams, and percent survival of fry in each replicate tanks 31 days after they swamup.

ReplicatereplicatereplicateTextThis is the letter designation of the fish tank the fish were reared in from swimup to 31 days postponding when survival and growth were assessed.
Average Weightaverage_weightaverage_weightNumberThis is the average weight in grams of the fry in this replicate tank that were alive 31 days after being ponded as first feeding swimup fry.
End numberend_numberend_numberNumberThis is the number of fish in the tank when they were examined 31 days after they were ponded as first feeding swimup fry.
Start numberstart_numberstart_numberNumberThis is the number of fish in the tank when they were ponded as first feeding swimup fry.
Average Lengthaverage_lengthaverage_lengthNumberThis is the average fork length in mm of the fry in this replicate tank that were alive 31 days after being ponded as first feeding swiump fry. Fork length is the length of a fish from the tip of its snout to the fork of its tail fin.
Hatchery Broodstockhatchery_broodstockhatchery_broodstockTextThis refers to the facility where the eggs were spawned and incubated at up to the eyed stage when they could be handled. The hatcheries were Idaho's Eagle Hatchery and NOAA's Burley Creek Hatchery.
Time spawnedtime_spawnedtime_spawnedTextThis refers to the portion of the spawning season when the eggs were spawned. The experimental facility received the eggs from early spawners in one shipment, the eggs from middle spawners in a second shipement, and eggs from late spawners in a third shipment.
Incubation temperatureincubation_temperatureincubation_temperatureTextThis refers to the temperature of the water eggs were incubated in from the eyed stage when they were received to the swimup stage when they first began to feed. Chilled eggs were incubate in 6.5 degree C water and unchilled eggs were incubated in 9-10 degree C water.
Percent Survivalpercent_survivalpercent_survivalNumberThis is the percentage of the fish that were alive in the tank 31 days after they were ponded int the tank as first feeding swimup fry.
