Infection of skipjack tuna Katsuwonus pelamis (Linnaeus 1758) of Oman Sea with cestode Trypanorhyncha (Diesing 1863)
Numerous reports on existence of white cysts in musculature of skipjack tuna Katsuwonus pelamis and lack of information about the quality of cysts and individual responses of fish to them led the authors to focus on this fish as a commercially valuable species. This study investigated the histopathologic responses of skipjack tuna to highly prevalent cystic larval stages of Trypanorhyncha. Some...

متن کاملGluconeogenesis in hepatocytes isolated from the skipjack tuna (Katsuwonus pelamis)
Skipjack ~ U M (Karsuwonus pelamis) hepatocytes were isolated and determined to be viable based on ttypan blue exclusion, energy charge, and lactate dehydrogenase leakage. Trypan blue staining and red blood cell contamination were always less than 0.1 % , and lactate dehydrogenase leakage remained less than 1 % at 25°C for 10 h. The energy charge for freshly isolated cells ranged from 0.65 to 0...
متن کاملParasites of Skipjack Tuna, Katsuwonus Pelamis: Fishery Implications
The numbers of 26 types of parasites were counted in 878 fish, of which all but 3 we.e from 14 areas in the Pacific. Data from the 22 most reliable parasites gave no evidence of discrete stocks of skipjack tuna in the Pacific, either when analyzed singly or when using combinations of parasites in multivariate analyses. New Zealand fish carried many tropical parasites, particularly didymozoids, ...
متن کاملEffects of temperature change on acid-base regulation in skipjack tuna (Katsuwonus pelamis) blood.
The effects of temperature change (in vitro) on acid-base balance of skipjack tuna blood were investigated. By examining the relationship between blood pH and temperature (in vitro) under conditions of constant CO2 tension (open system), it was observed that dpH/dT = -0.013 U/degrees C. This value falls well within the range of in vivo values reported for other ectothermic vertebrates, and is o...
