Invasion status of introduced species according to the European Seas considered (including adjacent waters)
Source publication
More than 1,000 non-indigenous aquatic species have been recorded, in total, from coastal Europe, i.e. navigational inland waterways for ocean-going vessels and adjacent water bodies in close proximity. Regions considered in this overview range from European Arctic waters to the Mediterranean Sea and Irish waters to the Black Sea. The majority of i...

... Numerous studies have shown that commercial fish and shellfish aquaculture have resulted in the introduction of alien aquatic organisms, intentionally and accidentally, around the globe (Carlton, 1992;Carriker, 1992;Consuegra et al., 2011;Cossu et al., 2021;Hindar et al., 1991). The genetic structure of aquaculture species can become complex due to the introductions of populations that differ from their natural counterparts (Gollasch, 2006;Strauss et al., 2006;Dlugosch and Parker, 2008;Danancher and Garcia-Vazquez, 2011) and introductions, in turn, may affect their ability to adapt to changing temperatures (Kolbe et al., 2010;Kolbe et al., 2012). ...
Climate change and human activity are essential factors affecting marine biodiversity and aquaculture, and understanding the impacts of human activities on the genetic structure to increasing high temperatures is crucial for sustainable aquaculture and marine biodiversity conservation. As a commercially important bivalve, the Manila clam Ruditapes philippinarum is widely distributed along the coast of China, and it has been frequently
introduced from Fujian Province, China, to other regions for aquaculture. In this study, we collected four populations of Manila clams from different areas to evaluate their thermal tolerance by measuring cardiac performance and genetic variations using whole-genome resequencing. The upper thermal limits of the clams showed high variations within and among populations. Different populations displayed divergent genetic compositions,
and the admixed population was partly derived from the Zhangzhou population in Fujian Province, implying a complex genomic landscape under the influence of local genetic sources and human introductions. Multiple single nucleotide polymorphisms (SNPs) were associated with the cardiac functional traits, and some of these SNPs can affect the codon usage and the structural stability of the resulting protein. This study shed light on the importance of establishing long-term ecological and genetic monitoring programs at the local level to enhance resilience to future climate change.
... Müller, 1776)) . The morphological identification of several species belonging to this family is often confusing because of a high intraspecific variation of the characters (e.g. in the pharynx and the parapodia), variable colour patterns, and the presence of cryptic/pseudocryptic species (Glasby et al. 2013). The relatively recent integration of the traditional morphological identifications with DNA barcoding (Hebert et al. 2003) helped unveil the presence of potential species complexes. ...
A new species of annelid, Alitta yarae sp. nov., is described from material collected in southern Brazil. This species was collected mostly from fishing buoys but also in muddy substrates of the following estuaries: Paraná Estuary Complex, Guaratuba, and Babitonga Bay. Alitta yarae sp. nov. belongs to a group of species with pennant-shaped posterior dorsal ligules. The most similar species of this group is A. succinea, which shares glandular structures from posterior dorsal ligules on lower edge only and having yellow-amber mandibles. However, the two species differ in the extension of the bare space between areas VI and VII–VIII, which is reduced in A. yarae sp. nov. and wider in A. succinea (respectively shorter than or equal to the palpophore), and the paragnath arrangement. Molecular analysis recovered ~20% genetic distance from the closest species A. succinea and no pattern of segregation among the estuaries studied. Finally, both the morphological and the molecular analyses strongly support the designation of a new species.
... These harmful and invasive NIS have a great negative impact on the aquatic ecosystem and local economy around the world. More than 1000 non-indigenous aquatic species have been transferred to coastal Europe and produced a great harm like the anoxic water bloom in Bilbao Harbor (Gollasch, 2006;Butrón et al., 2011). The NIS invasion events in North America have increased exponentially and in U.S. cause annual economic loss over $100 billion (Ruiz et al., 2001;Miller et al., 2007). ...
The Ballast Water Management Convention now enters the experience-building stage, but developing countries have no adequate ballast water information yet. Against this background, considering the richness and generality of common port statistics, we develop a new generic approach to estimate discharge volumes and assess associated risks. This is one of the few efficient and feasible ways for port authorities to manage real discharged ballast water. Discharge volumes during 2017-2020 and risks in 2017 are analyzed for bulker and tanker. Results show that: (1) Ports in Yangtze River Delta and Bohai Rim received most ballast water, especially Ningbo-Zhoushan port as high-risk region receiving about 65 million tons per year; (2) With a higher ratio of discharge volumes to cargo throughputs, the tanker tends to release more ballast water than the bulker; (3) Chinese ports suffer more than 0.9 of the probability of non-indigenous species introduction. All these findings help implement convention globally.
... According to Dudgeon et al. (2006), factors such as anthropogenic activities and climate change are obstructing the stability of most freshwater ecosystems; thereby causing a loss in diversity of zooplankton (Geist, 2011;Alahuhta et al., 2019). A lot of research has been carried out on diversity of various types of plankton many of which have been associated with far ranging ecological and economic impacts (Sharma and Mankodi, 2011;Priyanka Malhotra, 2014;Kamlesh, Prahlad Dube (2018); Kumar and Khare, 2015;Pimentel et al., 2005;Gollasch, 2006;Connelly et al., 2007;Cuhel and Aguilar, 2013). There are some researches on zooplankton assemblage which show relations bet-ween zooplankton and environmental parameters in various water systems (Makarewicz et al., 1998;Tackx et al., 2004;El-Bassat and Taylor, 2007;Arimoro and Oganah, 2010;Ahmad et al., 2011;Sharma, 2011). ...
An assessment of Physico-chemical parameters and zooplankton diversity of Anambra River in Anambra State was conducted for a period of eight months from February 2021-September 2021. Water samples were collected from three sampling stations of the river every month in sterilized containers during the course of the study. The study stations are Umueri (S1), Anam (S2) and Otuocha (S3). The samples were analysed for both Physico-chemical attributes and zooplankton diversity. Zooplankton species were determined following standard procedures. A total of twenty three species of zooplankton were encountered in Anambra River. The abundance of zooplankton in Anambra was in the order: Protozoa (28.57%) > Crustacea (27.14%) > Insecta (26.67%) > Rotifera (17.62%). There were 66, 79 and 65 zooplanktons recorded for Station 1 (S1), Station 2 (S2) and Station 3 (S3) respectively in Anambra River. 8 zooplankton species cut across the 3 stations while 1(Lacane species), 2(Chaoborus species and Microcodon species) and 1(Sphaerophysa species) species were unique to Station 1 (S1), Station 2 (S2) and Station 3 (S3), respectively. Anambra River recorded high diversity indices value for Cruataceans = 1.779 and least value for Rotifera = 0.6365. The physico-chemical attributes of the river were investigated by measuring the degree of correlation with the plankton diversity. The zooplankton diversity of the river correlated significantly (p<0.05) with physico-chemical parameters. The result revealed a deterioration of water quality of the river due to industrial, commercial and anthropogenic activities. The status of zooplankton diversity of Anambra River was low indicating that the river is highly polluted and the water chemistry has direct effect on plankton diversity. Rotifera showed less number of zooplankton abundance in most of the sites in the river. Nutrient enrichment of the river, as a result of farming activities, industries, discharge of domestic wastes and effluents, has altered the structure of zooplankton community of the river. There is need for urgent management and conservation strategies to protect and restore the water quality of the river.
... The range expansion of aquatic non-indigenous species (NIS) can be caused by natural phenomena (e.g., migrations, facilitated by other species, oceanographic currents) or be humanmediated (Galil et al., 2019). The most prominent humanmediated dispersal vectors in aquatic ecosystems are intentional introductions, aquaculture, and shipping/boating (e.g., ballast water, hull fouling) (Gollasch, 2006;González-Ortegón et al., 2007;Cuesta et al., 2016). The invasion of exotic species is being accelerated worldwide as a consequence of expanding transport and commerce (Mack et al., 2000); for instance, non-native species have been reported in the Gulf of Cadiz since 1980, but have increased rapidly in the last five years (González-Ortegón et al., 2020). ...
The invasive Atlantic blue crab Callinectes sapidus has considerably extended its distribution along the Gulf of Cadiz and Moroccan coasts in the northeast Atlantic. This could indicate a new introduction event in the Gulf of Cadiz from the native area, in case of detectable genetic differences from the Mediterranean Sea populations. To test this and reconstruct the invasion, we assessed the genetic structure of crabs in the Gulf of Cadiz and Alboran Sea. We used sequences of the mitochondrial gene cytochrome c oxidase subunit I (COI), in almost its full length (1511 basepairs), of 149 individuals from three sites along the Spanish Mediterranean coast, two in the Alboran Sea, and two in the Gulf of Cadiz. Our data reveal low genetic variability, with only two haplotypes (here referred to as CSWM1 and CSWM2), compared to its known high genetic diversity in the native range, indicating a strong founder effect in the study region. Here we document an inversion of haplotype predominance between regions, haplotype CSWM2 being dominant in most of the Spanish Mediterranean coast, but less frequent in the Gulf of Cadiz and Alboran Sea. This suggests a secondary introduction of propagules into the investigated area, rather than a new introduction from the native area, nor a natural westward expansion with environmental selection of one haplotype over the other. Further studies with additional populations would help to better unveil the history of yet another invasive species in the Gulf of Cadiz.

Tecnologias em geral como por exemplo a Inteligência Artificial, sempre parece algo do futuro, coisas de filme científico, algo imaterial ou inalcançável para alguns de nós meros mortais. De forma mais simples do que nosso imaginário conduz, essas tecnologias já não fazem parte do futuro na aquicultura e sim do nosso presente. Exemplos claros de como essas tecnologias podem ser ou já são aplicados no setor aquícola são apresentados nesse capítulo, de forma equilibrada entre a generalização, para quem não é da área, mas tem curiosidade e interesse, e a particularização do tema em um nível maior de detalhes, para aqueles que já não querem ficar na superfície da informação. Tudo isso está contido no conceito da indústria 4.0, ou agricultura de precisão onde é feita uma breve contextualização antes dos interessantes exemplos do capítulo. E o mais relevante para as perspectivas atuais dessas tecnologias para o desenvolvimento da aquicultura brasileira, uma discussão do exigente mercado de trabalho e a direção que os técnicos profissionais devem seguir para compor esse grupo interdisciplinar no trabalho que não é mais caracterizado por um indivíduo e sim uma equipe desenvolvedora dos problemas que porventura são demandadas pelas empresas.
... Em geral, ambas as liberações acidentais e intencionais de espécies não indígenas são comumente bem documentadas e monitoradas (PEARSON; DUGGAN,2018;SEPÚLVEDA et al., 2013;SVENNING et al., 2017). No entanto, fugas de fauna não-alvo, como grupos de organismos (taxa) microscópicos liberadas na água em conjunto com os estoques de cultura alvo, são potencialmente esquecidos (DUGGAN;PULLAN, 2017;GOLLASCH, 2006).

Exponential growth in industrialization, urbanization, and commercialization activities in last three decades have contributed to the increasing number of bio-refractory contaminants in the wastewater and this continuous admittance of toxic and persistent organic pollutants in the wastewater are imparting hazardous impacts on the environment. The conventional physical and biological treatment technologies are not very efficient in treating the wastewater having toxic and refractory pollutants and researchers worldwide are working to develop more efficient and sustainable technologies for the same. In recent years, advanced oxidation processes (AOPs) have emerged to be efficient, promising and environmental-friendly methods for the treatment of wastewater having high degree of pollution in comparison to conventional wastewater treatment methods. AOPs have appeared as an important avenue of technologies involving treatment of recalcitrant pollutants through different pathways such as “Enhanced Electrolysis”, “Ultraviolet radiation”, “Ozonation”, “Sonolysis”, etc. Many AOPs are based on the in-situ generation of strong oxidants like hydroxyl radicals which can completely mineralize or degrade the organic pollutants into harmless products. This chapter reports the details about various AOPs including theirbasic principle, mechanism, advantages, and limitations of each method to gain better scientific understanding of the most feasible approach to treat industrial wastewater. The authors have tried to summarize some recent AOPs too, which are being practiced seeing the disadvantages of the conventional AOPs. The contents will help to understand the future sustainable challenges for wastewater treatment (WWT).

Endocrine disruptors are toxic substances having adverse effects on the endocrine system even in very fewer amounts which appeared to be a serious concern for human health and water quality. EDCs (Endocrine disrupting compounds) behave like natural hormones in human beings that cause an interruption in endogenous hormonal activities like decreased fertility, changed sexual behavior, inflate abnormalities, and cancers in humans or animals. There are growing concerns about the effects of EDCs on drinking water or human health which are the key environmental problems worldwide. They can be removed from wastewater by many methods such as absorption, adsorption, oxidation, chemical degradation, photocatalytic degradation, membrane separation, biological degradation, transformation, and volatilization. The toxic effect of some EDCs is not fully known and needs further investigations. Detailed treatment methodology for each process is discussed for a better understanding of the scientific community for mitigation and handling these EDCs. The effect of influential operational parameters on the eradication of EDCs from aqueous media via various processes has been highlighted. Finally, the future perspective of the various water treatment techniques along with the key challenges to be faced by the next generation researchers towards expulsion of EDCs is discussed.
