Relationship among Ballast Water, Bioincrustration and Invasion of Exotic Species

Ballast water is one of the main vectors of transport of nuisance species among marine ports. Neither treatment nor interchange completely reduces the risk of ballast water containing DNA from harmful species, being a signal of potential threat. However, although there are some efficient treatments, they are not available on all ships and there might be some technological/economical constrains for their active and routine usage. Understanding what routes lead to a higher risk of contamination is important for designing targeted surveillance. We analysed ballast water from seven ships arriving in Gijon port (south Bay of Biscay, Spain). DNA metabarcoding was employed for identification of exotic species and harmful algae. One ship carried DNA of 20 risk species in the ballast water. Three ships contained DNA of only one risk species, and three ships had none. Seventy two algae species were found, 22.2% are exotic to the Bay of Biscay and 11.1% are catalogued as harmful. The results demonstrated the importance of continuous surveillance of ballast water.

Density And Biomass

The present study reports the occurrence of two exotic species of polychaetes in Izmir Bay, the eastern Mediterranean: Streblospio gynobranchiata, newly reported for the Mediterranean, and Polydora cornuta. Their establishment in the area is most probably transport by ballast water since these two species greatly dominated polluted muddy bottoms near and in Alsancak Harbour. The maximum density and biomass of S. gynobranchiata in the area were 34,270 ind m−2 and 9·4 g wwt m−2, and those of P. cornuta were 3170 ind m−2 and 2·1 g wwt m−2, respectively. These two species accounted for more than 60% of total faunal populations in the majority of samples collected in winter. Both species are capable of reproducing in the area both in summer and winter. The morphological, ecological and distributional characteristics of these species as well as their impacts on the prevailing ecosystem are analysed and discussed.

RESUMO O Porto do Recife recebe uma grande quantidade de navios de vários tipos e de muitas partes do mundo, podendo trazer espécies exóticas incrustadas no casco ou em água de lastro. O objetivo do presente estudo foi registrar e analisar os padrões de recrutamento de espécies bentônicas sésseis, assim como investigar uma possivel introdução de espécies bentônicas exóticas e criptogênicas em uma área portuária com grande fluxo de navios. Utilizaram-se placas de metal galvanizado para estudo do recrutamento de animais sésseis e sedentários em três pontos amostrais no porto, com três réplicas cada, totalizando nove pontos, durante seis meses (outubro de 2010 a março de 2011), considerado como período seco. As placas de recrutamento foram retiradas a cada 30 dias durante seis meses. As principais espécies de acordo com a área de cobertura foram Mytella charruana (72%) e Amphibalanus improvisus (22%) e espaços vazios (7,5%). Não houve diferença significativa quando comparadas as três estações no porto do Recife, sendo encontradas diferenças quando comparadas os dados das áreas de cobertura das espécies mais abundantes no recrutamento. Foram elas: Clytia gracilis, Obelia dichotoma, M. charruana e A. improvisus. ABSTRACT The Port of Recife receives a large number of vessels of various types and from many parts of the world, and can bring exotic species encrusted hull or in ballast water. The aim of this study was to record and analyze the patterns of recruitment of sessile benthic species, as well as investigating a possible introduction of exotic and cryptogenic benthic species in a port area with great flow vessels. We used galvanized metal plates to study the recruitment of sessile and sedentary animals at three stations in the harbor, with three replicas each, totaling nine points, six months (October 2010 to March 2011), considered the dry . The plates recruitment were taken every 30 days for six months. The main species according to coverage area were Mytella charruana (72%) and Amphibalanus improvisus (22%) and voids (7.5%). There was no significant difference when comparing the three stations in the Port of Recife, differences were found when comparing the coverage areas of most abundant species in recruitment. They were: Clytia gracilis, Obelia dichotoma, M. charruana and A. improvisus.

The confirmed freshwater fishes of Iran comprise 202 species in 104 genera, 28 families, 17 orders and 3 classes found in 19 different basins. There are also 23 species whose presence in Iranian waters needs confirmation by specimens. The most diverse order is the Cypriniformes with 120 confirmed species (59.4%) followed by Perciformes with 28 species (13.9%), Cyprinodontiformes (10 species, 5.0%), Clupeiformes (9 species, 4.5%), Salmoniformes (7 species, 3.5%), Mugiliformes and Siluriformes each with 6 species (3.0%), Acipenseriformes (5 species, 2.5%), Gasterosteiformes (3 species, 1.5%), and 8 other orders each with one species (0.5%). New species are still being discovered, 7 described in 2009, while others are being resurrected from synonymy, newly recorded from Iran, or exotic species newly established. Some taxonomic problems remain and are commented on briefly. Thirty-nine endemic species (19.3%) in 6 families and 23 exotic species (11.4%) in 8 families are listed here. The mosquitofish, Gambusia holbrooki Girard, 1859 is the most widespread exotic species.
