“…Circadian rhythm appeared significantly altered as compared with controls, with aggressive behaviors also appearing altered: considering the setting and the possible confoundings, more data might be required to better establish a clearer causal link. MLT exposure appeared associated with a reduction in aggressiveness and lipid peroxidation in Brycon amazonicus , a species known for engaging in cannibalistic behaviors and for being subject to oxidative stress related to being kept in artificial environments 49 . As feeding fish with a tryptophan‐enriched diet was known to decrease aggressive behavior, Lepage et al 50 investigated whether this effect was mediated by the central serotonergic and/or MLT systems of which tryptophan is the common precursor.…”

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 behaviors. To this end, we performed a systematic review on Embase and Pubmed/MEDLINE of preclinical and clinical evidence linking the melatonin system, melatonin, and melatoninergic drugs with aggressive/violent behaviors. Two blinded raters performed an independent screening of the relevant literature. Overall, this review included 38 papers distributed between clinical and preclinical models. Eleven papers specifically addressed the existing evidence in rodent models, five in fish models, and 21 in humans. The data indicate that depending on the species, model, and timing of administration, melatonin may exert a complex influence on aggressive/violent behaviors. Particularly, the apparent contrasting findings on the link between the melatonin system and aggression/ violence (with either increased, no, or decreased effect) shown in preclinical models underscore the need for further research to develop more accurate and fruitful translational models. Likewise, the significant heterogeneity found in the results of clinical studies does not allow yet to draw any firm conclusion on the efficacy of melatonin or melatonergic drugs on aggressive/violent behaviors. However, findings in children and in traits associated with aggressive/ violent behavior, including irritability and anger, are emerging and deserve empirical attention given the low toxicity of melatonin and melatonergic drugs.

“…It can be demonstrated that the reduction in luminosity due to the turbidity of the water in the bio oc system contributes to a reduction in aggressive behaviour and an increase in the productivity of the species, as previously demonstrated by Izel- Silva et al (2024). A reduction in light intensity in the water leads to an increase in melatonin production, which in turn reduces the aggressive behaviour of matrinxã larvae and juveniles (Lopes et al 2018;Amaral et al 2020; Souza-Cornélio et al 2021). It may also contribute to the reduction of protein levels in the feed, as already studied with tilapia (Oreochromis sp.)…”

This study evaluated potential for rearing the matrinxã, Brycon amazonicus, under different crude protein (CP) levels, using production performance, water quality and animal welfare as indicators. To achieve this, 720 juvenile fish (3.65 ± 0.17 g) were distributed across 24 experimental units (200 L) and fee study lasted 60 days. The study followed a factorial design (2x4), with two production systems: Biofloc technology (BFT) and clear water (CW), and four levels of crude protein (CP = 24%, 30%, 36%, and 42%) in the diet, with three repetitions for each. The study found that the BFT system showed a lower total ammonia level. However, the production system did not have any effect on pH or nitrite concentration. Oxygen levels were found to be lower in the 42% CP group. Fish produced in the BFT exhibited better performance of apparent feed conversion, productivity, and survival. The production system affected total leukocytes and neutrophils in the blood. There was no significant difference in carcass crude protein content and the ether extract content was higher in the animals from the BFT system. Nutritional composition of the biofloc showed differences for ash, with lower levels in the 42% CP treatment. In conclusion, juvenile matrinxã can be fed a diet containing 30% CP in both production systems. Furthermore, the results demonstrated that biofloc did not confer a direct benefit to matrinxã juveniles in terms of their feeding, however BFT represented a promising alternative for increasing the survival and improved animal welfare during the rearing phase.
