Effects of food quantity on aggression and monoamine levels of juvenile pufferfish (Takifugu rubripes).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aggressive behavior is important for animals to obtain limited resources. Understanding fish behavior and physiological response is of great significance to evaluate aquaculture production and fish welfare. Food is an important trigger of aggressive behavior in juvenile fish under high-density aquaculture conditions. The aim of this study was to investigate the aggressive behavior and monoamine levels of juvenile pufferfish (mean body mass of 6.29 ± 0.33 g) under normal feeding and restricted feeding. Our main results included the following: (1) The mortality and fin damage were higher and aggression was more intense of juvenile pufferfish at the 1% ration than those of the 3% ration; (2) during feeding, the velocity, body contact, and activity at the 1% ration were significantly higher than that of the 3% ration; (3) the concentrations of brain 5-hydroxyindoleacetic acid (5-HIAA) and monoamine oxidase A (MAOA) at the 1% ration were significantly lower, and dopamine (DA) concentrations were significantly higher. These results suggest that juvenile pufferfish shows serious aggressive behavior at the low ration, which may be related to the decrease of 5-HIAA and MAOA concentrations, and the increase of DA concentrations.
