Abstract

This study aimed to develop a technique to accelerate fish growth without using genetic modification or genome editing. We have prepared a reactor with four pairs of opposed electrodes and a high-voltage power supply for the discharge. An arc discharge generates a plasma-treated gas in the reactor. Plasma-treated gas containing active species such as nitric oxide (NO) was generated via an arc discharge in the atmosphere and inserted into an aquarium containing Nile tilapia. No ozone was detected in the plasma-treated gas. Plasma treatment gas was supplied to the 20 L tank at a flow rate of 10 L per minute for varying supply times. The supply duration of plasma-treated air to the water tank was 0.5, 2, 5, and 15 min. Tanks were prepared for each of these four conditions, and gas was supplied daily at the same time. We observed that on supplying plasma-treated gas to tilapia from the 16th week of age for 5 min daily, the average length of the fish at 31 weeks of age was ∼1.5 times longer than that of the control fish. All other supply time conditions were also found to grow acceleration over the control. In the 15-minute supply time condition, individual differences in body length were more significant. A sample had more growth suppression than controls. In other words, the results suggest that an excess supply of active species can cause growth inhibition. These results suggest that an optimal supply of plasma-treated gas has a growth-promoting effect on fish.Key policy highlightsThe fish growth was accelerated by supplying plasma-treated air to the tank.The amount of ozone in the plasma-treated air was below the detection limit, and a large amount of RNS, such as nitric oxide, was generated.After an experimental period of 16 to 31 weeks, the average length of fish in the most significant growth condition was 1.5 times that of the control fish.

尼罗罗非鱼在21至31周龄时用等离子体处理的空气供水加速生长。
这项研究旨在开发一种技术,在不使用基因改造或基因组编辑的情况下加速鱼类的生长。我们准备了一个有四对相对电极的电抗器和一个用于放电的高压电源。电弧放电在反应器中产生等离子体处理过的气体。等离子体处理后的气体含有活性物质,如一氧化氮(NO),通过电弧放电在大气中产生,并插入一个含有尼罗罗非鱼的水族箱中。在等离子体处理过的气体中未检测到臭氧。等离子体处理气体以每分钟10升的流量供应到20升的储罐,供应时间不同。等离子体处理空气向水箱的供气时间分别为0.5、2、5和15分钟。为这四种情况分别准备了储罐,每天同时供应天然气。我们观察到,从16周龄开始,每天向罗非鱼提供5分钟的等离子处理气体,31周龄的罗非鱼的平均长度是对照鱼的1.5倍。所有其他供应时间条件也被发现比控制条件增加加速度。在15分钟供给时间条件下,体长的个体差异更为显著。一个样本比对照有更多的生长抑制。换句话说,研究结果表明,活性物种的过量供应会导致生长抑制。这些结果表明,等离子体处理气体的最佳供应对鱼类有促进生长的作用。通过向鱼缸提供等离子体处理过的空气,鱼的生长速度加快了。等离子体处理后的空气中臭氧含量低于检测限,并产生大量一氧化氮等RNS。经过16 ~ 31周的试验期,生长最显著的鱼的平均体长是对照鱼的1.5倍。
