Evidence for Expatriate Populations of the Lanternfish Myctophum punctatum in the Northwest Atlantic
Myctophum punctatum populations in the Northwest Atlantic are probably expatriate, being composed almost exclusively of very large individuals and lacking postlarvae. Females do not possess maturing or gravid ovaries. The apparent physiological stress on these fish is reflected by irregular and some...

Females do not possess maturing or gravid ovaries. The apparent physiological stress on these fish is reflected by irregular and sometimes regressive growth evidenced in their scales, otoliths and subopercles. |
