Evidence of spawning by hermaphroditic skipjack tuna
Hermaphroditic gonads were collected from three skipjack tuna Katsuwonus pelamis in the western and central Pacific Ocean. Both ovarian and testicular tissues were found in the same gonad lobe for each of the three fish. Histological sections of the hermaphroditic gonad from one K. pelamis showed postovulatory follicles, which is evidence of spawning.

Sensitivity of restrained skipjack tuna (Katsuwonus pelamis) to abrupt increases in temperature
Comparative Biochemistry and Physiology Part A: Physiology, 1974Abstract 1. 1. Restrained skipjack tuna (Katsuwonus pelamis) signaled by deceleration of heart rate that they could perceive abrupt temperature increases (1°C/sec) as small as 1°C. 2. 2. A thermal stimulus directed into the oral-branchial cavity was more effective in eliciting responses than stimuli delivered to the nasal cavity or the dorsal,

Digestion and Food Consumption by Skipjack Tuna (Katsuwonus pelamis)
Transactions of the American Fisheries Society, 1969Abstract Skipjack tuna, 39–50 cm fork length, were studied during their first month in captivity in tanks 7.3 m in diameter and 1.1 m deep. Water temperatures were 23.3° to 25.7° C. Passage of food through the alimentary canal was estimated from 54 fish that were fed as many thawed smelt as they would eat.

Visual Acuity of Two Tunas, Katsuwonus pelamis and Euthynnus affinis
Copeia, 1968Two tunas, Katsuwonus pelamis and Euthynnus affinis, were trained to discriminate between vertically and horizontally striped images. The striped images were projected on a plate of opal glass which rested against a window of the experimental tank. Visual acuity depended upon the width of the stripes and the distance between the fish and the window at ...
