A Brief Review on Aflatoxicosis in Aquaculture With a Focus on Fish. [PDF]

Aquac Nutr
Feed quality is among the most determinative criteria for aquaculture success. Along with feed ingredient quality and its production process, feed storage conditions would also affect feed quality, especially in terms of adventitious toxins. Mycotoxins are frequent food and feed contaminants and are considered important health threats to both human and

Effect of stocking density in plastic boxes without oxygenation on the transport of pirarucu, Arapaima gigas (Schinz, 1822)

Journal of the World Aquaculture Society, Volume 53, Issue 5, Page 1031-1041, October 2022., 2022
Abstract For the evaluation of the effects of the transport density of pirarucu juveniles, 210 juvenile pirarucus, Arapaima gigas (488 ± 26.5 g) were randomly distributed in 12 plastic boxes at transport densities of 98, 146, 195, and 244 g L−1. The transport was carried out on a paved highway for 4 h, and at the end of the transport, all were returned

The Amazon river is a suture zone for a polyphyletic group of co‐mimetic heliconiine butterflies

Ecography, Volume 44, Issue 2, Page 177-187, February 2021., 2021
The Amazon basin contains few obvious geographic barriers, yet it is the most biodiverse region on Earth. One hypothesis to explain its diversity is that the very large rivers promote allopatric divergence. Consistent with this, maps of heliconiine butterflies made from museum specimens show high subspecies richness close to the Amazon river ...
