Toxicity of puffers from Okinawa, Japan.

A total of 65 specimens of puffers comprising nine species of the suborder Tetraodontoidei were collected from Okinawa and tested for toxicity levels of the flesh, skin, liver, gonad, and intestine. Chelonodon patoca, Arothron manillensis, A. nigropunctatus, and A. hispidus showed high toxin levels in the flesh and thus should be banned from being eaten. Toxicities of the flesh of A. mappa, A. stellatus, Pleuranacanthus sceleratus, and Fugu niphobles were within an acceptable level. Diodon hystrix, which is widely consumed locally, showed no significant level of the toxin in all tissues tested. Extremely high toxicities of the flesh of C. patoca (520 MU/g) and A. nigropunctatus (184 MU/g) are worthy of special mention.

Feeding ecology of four fishes from a mangrove creek in north Queensland, Australia

The feeding ecology of four species of fish is described in terms of associations of body form, feeding structures, and stomach contents; and of seasonal variations in diet. Black bream, Acanthopagrus berda (Forskal, 1775), and the hair‐finned goby, Ctenogobius criniger (Valenciennes, 1837), are predominantly carnivorous; milk‐spotted toadfish, Chelonodon patoca (Hamilton‐Buchanan, 1822), largely omnivorous; and bony bream, Anodontostoma chacunda (Hamilton‐Buchanan, 1822), detritivorous. The results illustrate the role of a mangrove creek in the ecology of the four species of fish and show the mangrove creek provides a nursery for A. berda and C. patoca.
