“…In any case, it should be highlighted that efforts related to controlling invasives through human consumption should thoroughly examine the potential production of opposite results than those expected [44]. For example, Nunez et al [45] mention that a market for invasive species could encourage local communities to protect those harmful species, and Meadows and Sims [46] emphasize that the invasive species' potential dual role (as both a pest and a commodity) may alter incentives to eradicate or exacerbate an invasion.…”

The effect of thermophilic species invasion in the eastern Mediterranean is well-noted in the literature. During the last decade in western Greek waters, small-scale fisheries (SSF) catches exhibit increased relative contribution of rabbitfishes, which have originated from the Red Sea and inhabited the country’s southeastern part since the Second World War. This study has used quantitative and qualitative information to assess the short-term economic effect of the rabbitfishes’ expansion in the SSF métier targeting the indigenous thermophilic parrotfish in the South Ionian Sea. The short-term micro-level negative economic effects of the rabbitfishes’ invasion and the corresponding adverse effects on fishers’ economic wealth have been estimated. The results indicate attitudinal differences among fishers, although their local ecological knowledge may enable them to avoid rabbitfishes’ hot spots and mitigate the respective economic losses, that particularly for smaller SSF vessels already seem to be quite important. As climate warming may further facilitate the expansion of rabbitfishes, outcompeting parrotfish, the latter métier may eventually become economically unsustainable. Fine-scale analysis at the métier level enables addressing the specificities of social-ecological systems and can contribute to informed and more effective decision making related to SSF, which is an important building block of Mediterranean coastal communities.

“…Further efforts to introduce these species in the local menu could possibly serve as a mitigation measure for regional population control. Yet such initiatives should be planned with caution in order not to encourage intentional introductions to new areas and/or a fishery métier that might collapse and lead local fishers to economic losses (e.g., [28]).…”

Looking at the Expansion of Three Demersal Lessepsian Fish Immigrants in the Greek Seas: What Can We Get from Spatial Distribution Modeling?

et al. 2023

A big number of Red Sea species have entered the Mediterranean Sea since the opening of the Suez Canal. Some of them quickly establish local populations and increase their abundance, forming a potential threat for local biodiversity and fisheries. Here, we use habitat modeling tools to study the expansion of three alien, demersal fish species that entered the Mediterranean basin at different times: Pterois miles, Siganus luridus and Siganus rivulatus. Georeferenced occurrence data from the eastern Mediterranean over the past ten years were compiled using online sources, published scientific literature and questionnaires and were correlated with environmental and topographic variables. The maximum entropy modeling approach was applied to construct habitat suitability maps for the target species over all of the Greek Seas. Results emphasized the three species’ strong coastal nature and their association with the presence of Posidonia oceanica meadows. Probability maps evidenced that for all species there is a higher likelihood of presence along the southeast and central Aegean and Ionian Sea coasts and a lower likelihood throughout the North Aegean Sea. For Siganus spp., predictions in the Thracian Sea were highlighted as highly uncertain, as the environmental conditions in this area partly fall outside the range of values occurring in locations of their current presence.

Can Environmental or Local Information Help Manage an Invasive Species Through Consumption?

The consumption of invasive species could be an opportunity to regulate these species to limit the negative environmental impacts. However, the commercialisation of an exogenous species raises several questions. We assess the acceptance of wels catfish, an invasive species in an alpine lake, and the willingness to pay (WTP) for environmentally friendly and locally produced wels catfish products. The results show that knowledge is an important dimension to explain consumption. Informing consumers about an environmental or local dimension increases WTP for wels catfish, but it does not increase product acceptance. There is no additional premium when both types of information are used together.
