摘要
本文报道了在广州地区某一半自然水体中发现的入侵物种食蚊鱼(Gambusia affinis)对另一入侵物种罗非鱼(Oreochromis sp)仔鱼捕食现象一例。在一尾体长24.10mm的雌性食蚊鱼消化道中发现3尾罗非鱼仔鱼,其体长分别为6.68 mm、5.85 mm、5.67 mm。
We found three Oreochromis sp. Larvae in the gut of an adult female mosquito fish （Gambusia affinis） with the body length of 24.10 mm, which was collected from the Ming Lake, Guangzhou on Mar. 18, 2009. Body length of those Oreochromis sp. larvae was 6.68, 5.85 and 5.67 mm, respectively. This finding indicated that the two invasive species, mosquito fish and Oreochromis sp., may interact by such predation in the Ming Lake.
