Abstract
Light-sticks shine resulting from a chemiluminescent reaction between two components kept separate by a glass ampoule. Light-stick baits are discarded in the ocean after being used in longline fishing. The traditional Brazilian community of Costa dos Coqueiros, Brazil, uses the discarded light-sticks chemical contents found on beaches as medicine for rheumatism and mycoses. This study assessed the effects that light-sticks (chemical contents) have on Pachygrapsus transversus and Litopennaeus vanammei. Assays of metabolic changes involved rates of ammonia excretion and oxygen consumption. The EC50–60 min to juveniles and adults P. transversus were 0.0004% and 0.0046%, respectively; and L. vanammei revealed a susceptible species: EC50–60 min of 0.0006% for oxygen uptake and 0.0072% for ammonia excretion, and also was observed a hormesis effect in the ammonia excretion. Light-stick contents could promote significant metabolic changes in rocky crabs and gray shrimp. Educational actions are needed that make the population aware of and avoid the dangerous misuse of the light-sticks.

弃置灯棒的化学成分影响横纹石蟹 Pachygrapsus 和灰虾 Litopennaeus vanammei 的生理
摘要
由玻璃安瓿分开的两种成分之间的化学发光反应导致荧光棒发光。光棒鱼饵用于延绳钓后被丢弃在海洋中。巴西 Costa dos Coqueiros 的传统巴西社区使用在海滩上发现的废弃荧光棒化学成分作为治疗风湿病和真菌病的药物。本研究评估了荧光棒（化学成分）对Pachygrapsus transversus和Litopennaeus vanammei 的影响。代谢变化的测定涉及氨排泄率和耗氧量。所述EC50-60分钟至青少年和成人P.横突分别为0.0004％和0.0046％，; 和L. vanammei揭示了一种易感物种：EC50-60 分钟的氧摄取为 0.0006%，氨排泄为 0.0072%，并且还观察到氨排泄中的兴奋效应。荧光棒含量可促进石蟹和灰虾的显着代谢变化。需要采取教育行动，让人们了解并避免误用荧光棒的危险。
