Bergen, Norway.- So far, fish have been spared the problem of mycotoxins produced by mould, but the increase of plant ingredients in farmed fish feed has resulted in more such toxins in fish feed too. Many ‘new’ toxins have been discovered, and we know little about any consequences they may have for fish and people.

China.- A new high-definition genome sequence of the sea cucumber provides molecular insights into its ability to regenerate, according to a new study publishing 12 October in the open access journal PLOS Biology by Xiaojun Zhang, Lina Sun, Hongsheng Yang and Jianhai Xiang, of the Institute of Oceanology, Chinese Academy of Sciences, and colleagues. The genome sequence also helps explain why the sea cucumber has such a radically different skeletal structure from other members of the echinoderm phylum, and may be useful for understanding evolution of the animal kingdom.

Barcelona, Spain.- Surprisingly, low concentration of toxic chemical products in rivers –from fungicides to antidepressants- can change the swimming and feeding behaviours in some creatures, according to a new research study led by experts from the University of Barcelona and the University of Portsmouth (United Kingdom). Also, the effects can be unexpected depending on the kind of toxin mix, according to this study published in the journal Environmental Pollution.
