Hans-Georg Evers starts our Aquatic Notebook by introducing a pioneering effort by Hudson Crizanto Gonçalves to estasblish a commercial catfish breeding project in Brazil, initially focusing on the production of highly desirable Pseudacanthicus species along with other species not currently on Brazil's “positive list” (approved for wild harvest). Also in this issue's Notebook: Black & White Stingrays, a cautionary tale and results from our Bloodworm Survey, breeding the freshwater pufferfish Tetraodon schoutedeni, and a new understanding of how fish are able to orient themselves facing into water current, even under the cover of darkness. It's a Notebook you won't want to miss!
