Experiments done in aquaria under control and either turbid or densely vegetated conditions indicated that three-spined stickleback Gasterosteus aculeatus sneaking behaviour is affected by decreased underwater visibility. Success of sneaking behaviour decreased significantly under increased turbidity but not increased vegetation density. The total number of sneaking attempts, including unsuccessful ones, was not affected by either form of decreasing visibility.
在控制条件下以及浑浊或植被茂密的水族箱中进行的实验表明，三刺鱼的潜行行为受到水下能见度降低的影响。在浊度增加的情况下，潜行行为的成功率显著降低，但植被密度增加则没有影响。无论是能见度降低的哪种形式，都不会影响总潜行尝试次数，包括不成功的尝试。
