This paper reviews published knowledge on how to deal with invasive species during biological quality assessments in European river systems for water management and assessments of ecological quality required, for example, by the European Water Frame Work Directive. The papers studied included international papers and some standards for water assessment. An overview of the current state of neozoa research showed that many different topics are treated, comprising biogeography and fauna records, species replacements and effectiveness of colonisation, life cycles, competition between native and invasive species, habitat quality and pathways of migration. Additionally, some papers have been published recently on the integration of neozoa in index-based assessment systems. Although the decline or increase of alien species populations and the corresponding impacts on indigenous populations were frequently observed, the mechanisms behind the invasions often remain hypothetical. In the reviewed papers, issues such as possible reasons for coexistence, tolerances, quality of habitat or water, life history traits and introduction of diseases were rarely covered. Few neozoa are sufficiently investigated to be categorised as indicators. After discussing the advantages and disadvantages of inclusion or exclusion, inclusion of invaders in assessments of both biodiversity (all species) and human impact (only species classified in their specific tolerance) is suggested. Further research is required to (1) update and assign ecological profiles of the non-indigenous species currently and (2) assess the effects of new invaders on native communities.

“…Moreover, the frequency of recent invasion events of this species throughout the world (e.g. Robbins et al, 2006;De Lafontaine et al, 2008;Drotz et al, 2010;Garcia-de-Lomas et al, 2010;Pezy et al, 2015), also indicate that there is a potential risk of expanding E. sinensis invasion to other regions. Several studies have shown that many areas in the Iberian Peninsula (Capinha & Anastácio, 2011;Capinha et al, 2012), in the rest of Europe (Herborg et al, 2007a) and also throughout the world (Capinha et al, 2011) present suitable conditions for the invasion by this species.…”

Population structure and reproductive status of the invasive Eriocheir sinensis (Decapoda, Varunidae) in the Tagus estuary (Portugal)The Chinese mitten crab (Eriocheir sinensis, Milne Edwards, 1853) is a highly invasive catadromous species established in the Tagus river. Since there is insufficient data about the species in this invaded area, the aim of this study was to characterize its population structure and reproductive dynamics. This population is at a much lower latitude than most other well studied European E. sinensis populations, therefore strong differences should be expected, possibly affecting the choice of management strategies. E. sinensis bycatch was obtained in the upper Estuary using fyke nets on an approximately monthly basis from September 2013 to October 2014. Population structure, female gonad development, fertility, condition and growth were analyzed. An overall sex ratio of 1.54 (M/F) was found, but it oscillated significantly along the year. Ovigerous females were found from March to May, mostly during a period of low flow and high salinity (3-7 PSU). The average number of eggs per female was 36 350, which is low when compared with other areas where the species is established. Loss of appendages was observed in 44.4 % of the crabs, potentially affecting its commercial use. In conclusion, this well-established short lived population, presents an unusually low fertility which may explain why there have been no remarkable population explosions. To decrease the risk of larvae transport by ballast water from the Tagus to other nearby estuaries seasonal control measures could be applied from April to July.

A review of ballast water management practices and challenges in harsh and arctic environments

et al. 2012

Ballast water is carried by cruise ships, large tankers, and bulk cargo carriers to acquire the optimum operating depth of the propeller and to maintain maneuverability and stability. Recently, ballast water has been recognized as wastewater that is responsible for ocean pollution due to the worldwide transfer of non-indigenous species, pathogenic bacteria, and other pollutants via ballast water discharge. This poses serious environmental, ecological, and economic threats to both coastal communities and the marine environment. To address these negative impacts and concerns, the International Maritime Organization (IMO) has codified and adopted a series of guidelines to minimize pollution and adverse effects caused by ballast water. A number of treatment technologies have been developed and applied in field practices to remove solids, particulates, organic pollutants, and organisms from ballast water, showing certain advantages and limitations. Many other management practices, such as ballast water exchange (BWE), shipping routes optimization, treatment process modeling, and risk assessment are in high demand to aid onboard treatment systems. However, knowledge and technical gaps still exist regarding the implementation of ballast water management practices especially in the context of arctic and harsh environments under changing climatic conditions. Records indicate that most coastal regions in the north have been invaded by unwanted species via ballast water discharge in the past decades. The North Atlantic and the Arctic Oceans have much colder climates and more extreme weather conditions than low latitudes. The discharge of untreated or less treated ballast water could cause much more severe damage to the local environment and hence pose higher risks to ecosystems and even human health, particularly in the context of climate change. Based on a comprehensive literature review, this study proposed a risk-based fuzzy–stochastic–interval programming decision support system to help eliminate environmental, ecological, as well as health threats from the discharge of ballast water, particularly in the north where weather, space, timing, maintenance, and cost are major concerns.
