Estimating fishing and natural mortality rates for Pacific bluefin tuna (Thunnus orientalis) using electronic tagging data
Pacific bluefin tuna Mark-recapture Natural mortality Fishing mortality Spatial structure Electronic tagging data
2015/11/16
This paper presents estimates of fishing and natural mortality rates derived from a spatially- and seasonally structured Bayesian mark-recapture model for electronically tagged Pacific bluefin tuna (P...
Quantifying energy intake in Pacific bluefin tuna (Thunnus orientalis) using the heat increment of feeding
heat increment of feeding HIF archival tag caloric intake hierarchical Bayesian model
2015/11/16
Using implanted archival tags, we examined the effects of meal caloric value, food type (sardine or squid) and ambient temperature on the magnitude and duration of the heat increment of feeding in thr...
Heart rate responses to temperature in free-swimming Pacific bluefin tuna (Thunnus orientalis)
Ambient temperature visceral temperature cardiorespiratory cardiovascular oxygen consumption rate tail beat-frequency swimming speed thermal biology
2015/11/16
The bluefin tuna heart remains at ambient water temperature (Ta) but must supply blood to warm regions of the body served by countercurrent vascular heat exchangers. Despite this unusual physiology, i...
Amino Acid Isotope Incorporation and Enrichment Factors in Pacific Bluefin Tuna,Thunnus orientalis
Amino Acid Isotope Enrichment Factors Pacific Bluefin Tuna Thunnus orientalis
2015/11/16
Compound specific isotopic analysis (CSIA) of amino acids has received increasing attention in ecological studies in recent years due to its ability to evaluate trophic positions and elucidate baselin...
Bioenergetics of captive Pacific bluefin tuna (Thunnus orientalis)
Energetic model Growth rate VBGF Pacific bluefin tuna
2015/11/16
Tuna bioenergetics can be described by the following relationship: the energy available for growth is equal to the food energy minus all metabolic costs. These costs include routine metabolic rate, sp...
