This article presents a study about eradicating the Asiatic cyprinid Pseudorasbora parva from fishing lakes in England to prevent their riverine dispersal. It discusses that Pseudorasbora parva has proved to be a highly invasive pest fish species in mainland Europe following introduction from Asia, and was recorded in the wild in Great Britain in 1996. It demonstrates that riverine dispersal of invasive fish from infested connected lakes can be prevented by eradication and outputs can be used to develop a strategy to manage the increasing distribution of topmouth gudgeon.

The article presents a case study on the population ecology of a topmouth gudgeon, Pseudorasbora parva, in Great Britain. It is a small Asian cyprinid fish species that has been proved to be highly invasive. In addition, the life history traits of topmouth gudgeon include batch spawning, nest guarding and early maturity, which generally favor its ability to invade. The article also discusses the population establishment, abundance and growth of the P. parva in a lake.

The topmouth gudgeon ( Pseudorasbora parva) is a species that is becoming invasive in UK waters. Few biological studies have been completed on the species in this extended range, resulting in sparse information in some aspects of their invasion biology. Regarding length–weight relationships, this is remedied in this study by providing data for 10 lake populations in the UK. Using fish length range 2.5–11.8 cm, values of a and b in the length–weight equation are provided. Values of b ranged between 2.76 and 3.32. Across all lakes, the relationship was W = 0.011L3.03, with weight in grams and length (fork) in cm. [ABSTRACT FROM AUTHOR]
