Melatonin and aggressive behavior: A systematic review of the literature on preclinical and clinical evidence. [PDF]
J Pineal Res, 2022 Abstract The melatonin system and circadian disruption have well‐established links with aggressive behaviors; however, the biological underpinnings have not been thoroughly investigated. Here, we aimed at examining the current knowledge regarding the neurobiological and psychopharmacological involvement of the melatonin system in aggressive/violent ...

Anthropogenic Barriers Limit Fish Access to Essential Habitats in the Amazon in the Face of Climate Change. [PDF]
Glob Chang BiolRivers across the Amazon Basin are increasingly threatened by climate change and dam construction, which restrict fish movements. We combined climate projections with river‐network connectivity analyses to identify where suitable habitats for frugivorous and socioeconomically important fish are likely to persist and where access may be lost due to ...

Journal of the World Aquaculture Society, Volume 53, Issue 3, Page 652-668, June 2022., 2022 Abstract Chronic exposure to high biofloc total suspended solids (TSS) could affect growth, red blood cells, and generate gill alterations in fish. Red pacu, Piaractus brachypomus, fry (2.7 ± 0.5 g weight) were exposed to different biofloc TSS concentrations with low (T1: 200–300), and medium (T2: 400–600 mg/L) levels and compared to a treatment ...

Insect meals in fish nutrition
Reviews in Aquaculture, Volume 11, Issue 4, Page 1080-1103, November 2019., 2019 Abstract Different studies have shown that insect meals can partially or completely replace the fish and soya bean meals that are commonly used in aquaculture. However, information is lacking on the amino acid and fatty acid contents and digestibility of different insect meals. Moreover, we evaluated different proportions of insect diets and determined
