“…During the introduction and cultivation process, strengthening the inspection and control of diseases-as well as strengthening the management of Crassostrea gigas in various fisheries to avoid escape and dispersion during cultivation-can reduce the risk of Crassostrea gigas to a certain extent [61,62]. (4) The risk grade of Trachemys scripta elegans is medium. Although Trachemys scripta elegans is considered one of the 100 worst IS according to the IUCN and drives native freshwater turtles to consume suboptimal resources [63,64], the degree of control of non-native species is generally higher than that of pathogens.…”

“…Invasive species (IS) can cause serious damage to an ecosystem, which can lead to negative impacts on human society; these impacts include economic losses caused by trade and agricultural production obstacles and threats to human health [ 2 , 3 ]. An IS is a non-native species that has invasive biological characteristics (such as strong adaptability and spread capability) or may have negative impacts on ecology, agriculture, fisheries, food, or human health, including artificially introduced and unintentionally arrived nonindigenous species [ 4 , 5 , 6 ]. Another definition of IS is a non-native species that can have harmful effects on the economy, environment, or human health (supported by the International Union for Conservation of Nature (IUCN)) [ 7 ].…”

The spread of invasive species (IS) has the potential to upset ecosystem balances. In extreme cases, this can hinder economical utilization of both aquatic (fisheries) and terrestrial (agricultural) systems. As a result, many countries regard risk assessment of IS as an important process for solving the problem of biological invasion. Yet, some IS are purposefully introduced for what is seen as their potential economic benefits. Thus, conducting IS risk assessments and then formulating policies based on scientific information will allow protocols to be developed that can reduce problems associated with IS incursions, whether occurring purposefully or not. However, the risk assessment methods currently adopted by most countries use qualitative or semiquantitative methodologies. Currently, there is a mismatch between qualitative and quantitative assessments. Moreover, most assessment systems are for terrestrial animals. What is needed is an assessment system for aquatic animals; however, those currently available are relatively rudimentary. To fill this gap, we used the analytic hierarchy process (AHP) to build a risk assessment model system for aquatic IS. Our AHP has four primary indexes, twelve secondary indexes, and sixty tertiary indexes. We used this AHP to conduct quantitative risk assessments on five aquatic animals that are typically introduced in China, which have distinct biological characteristics, specific introduction purposes, and can represent different types of aquatic animals. The assessment results show that the risk grade for Pterygoplichthys pardalis is high; the risk grade for Macrobrachium rosenbergii, Crassostrea gigas, and Trachemys scripta elegans is medium; and the grade risk for Ambystoma mexicanum is low. Risk assessment of the introduction of aquatic animals using our AHP is effective, and it provides support for the introduction and healthy breeding of aquatic animals. Thus, the AHP model can provide a basis for decision-making risk management concerning the introduction of species.
