How much fluctuating asymmetry in fish is affected by mercury concentration in the Guanabara Bay, Brazil?

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
This study aims to analyze if the fluctuating asymmetry (FA) of the Corocoro grunt Orthopristis ruber is affected by mercury concentration in Brazilian Southeastern eutrophicated bay. The O. ruber fishes were collected in two areas of the Guanabara Bay, Rio de Janeiro, Brazil: Vermelha Beach, influenced to ocean waters, and Paquetá Island, for greater freshwater loads of the rivers of the region, both in wet and dry seasons. Possibly availability of food resources, exposure to other pollutants and harmful agents (pesticide, algal toxicity, among others), and environmental and oceanographic factors may be reflecting on the FA detected for the O. ruber population. Mercury (Hg) is a harmful trace metal when present in the food, because of the high toxicity, high levels of absorption, and low excretion rate. Hg accumulates in human organisms through fish consumption, which may represent a risk to health. Analytical determinations of THg were performed by Direct Mercury Analyzer, following the manufacture's recommendations and following the procedure proposed by Guimarães et al. (Food Sci Nutr 4:398-408, 2015). No evidenced in the influence of THg on FA. In turn, the THg was significantly different between areas. Higher THg levels were found in O. ruber populations in the Vermelha Beach, with mean values of HgT 0.08 ± 0.01 mg/kg
