Albacore tuna, bigeye tuna, blue shark, shortbill spearfish, and striped marlin all showed declining CPUE trends; skipjack tuna, yellowfin tuna, ono, and lancetfish showed no significant trends; and mahimahi, sickle pomfret, escolar, and snake mackerel showed increasing trends (Table 1, Figs.
When an increase in longline fishing was simulated, the biomasses of blue shark, large sharks, brown shark, bigeye tuna, yellowfin tuna, albacore, swordfish, blue marlin, and other marlins all declined; however, the biomass of mahimahi, flying squid, and lancetfish increased (Kitchell et al.

Indeed, it was found to be the main cephalopod prey in all the fishes, except in bigeye tuna and lancetfish where it ranked second and third, respectively.

1) in good condition was found in the stomach of a lancetfish caught by pelagic longline on 17 May 1987 during a research cruise in the waters of the exclusive economic zone of Mauritius, western Indian Ocean.
The fork length (FL) of the lancetfish was 167 cm, its weight was 9 kg; FL of the yellowfin tuna was 37 cm and its weight was 790 g.
We have found slow-swimming animals in the stomachs of lancetfish (Zamorov et al.
3] in volume) juvenile swordfish (Xiphias gladius) from a lancetfish stomach was reported by Williams (1967).
keta) found with slash marks attributed to lancetfish likely indicate that lancetfish also prey on these fast-swimming fish (Radchenko and Semenchenko, 1996).
The jaw structure and large teeth of lancetfish allow these fish to hunt for relatively large animals.
5 body lengths per second (Brill (6)), which in the case of the tuna found in the lancetfish stomach corresponds to a rate of 48-55 cm/s.
