“…Globally, this equates to costs of US$ 1.5 to 3 billion yr 71 . While the direct costs of biofouling control have been estimated for many aquaculture species (salmon: US$ 0.03 and $ 0.12 per kg of salmon produced; Olafsen 2006; scallops: 30% of final market price; Claereboudt et al 1994; oysters: 20% of final market price; Enright 1993;Watson et al 2009), the indirect effects of fouling on the production of cultured species remain largely unassessed. The production chain inefficiencies associated with biofouling are substantial, Table 1.…”

Biofouling in marine aquaculture is a specific problem where both the target culture species and/or infrastructure are exposed to a diverse array of fouling organisms, with significant production impacts. In shellfish aquaculture the key impact is the direct fouling of stock causing physical damage, mechanical interference, biological competition and environmental modification, while infrastructure is also impacted. In contrast, the key impact in finfish aquaculture is the fouling of infrastructure which restricts water exchange, increases disease risk and causes deformation of cages and structures. Consequently, the economic costs associated with biofouling control are substantial. Conservative estimates are consistently between 5-10% of production costs (equivalent to US$ 1.5 to 3 billion yr 71 ), illustrating the need for effective mitigation methods and technologies. The control of biofouling in aquaculture is achieved through the avoidance of natural recruitment, physical removal and the use of antifoulants. However, the continued rise and expansion of the aquaculture industry and the increasingly stringent legislation for biocides in food production necessitates the development of innovative antifouling strategies. These must meet environmental, societal, and economic benchmarks while effectively preventing the settlement and growth of resilient multi-species consortia of biofouling organisms.

“…In both cases, fouling community increased the time for farmed mussel to reach the commercial size. Enright et al (1983), Dittiman & Robles (1991), Enright et al (1993), Flimlin Jr. & Mathis Jr. (1993, Claereboudt et al (1994), Lodeiros & Himmelman (1996), Taylor et al (1997), Cigarría et al (1998) also observed that fouling had reduced the weight and/or size of cultivated bivalves. However, Monteiro & Silva (1995) and Metri et al (2002), using different treatments for elimination of the fouling, did not observe significant variations in the length of the mussels with or without fouling; Freitas (1997) observed a small decrease in the size and weight of the mussels without fouling (compared to those with them), probably due to the treatment to eliminate fouling (aerial exposure).…”

“…However, the competition happens mainly for space for attachment, because fouling covers the shells, preventing the bivalves from opening their valves (Arakawa, 1990;Lesser et al, 1992;Lodeiros & Himmelman, 1996). The great amount of these organisms can reduce the water flow for the bivalves, causing a decrease in the amount of food and oxygen (Arakawa, 1990;Claereboudt et al, 1994).…”

A B S T R A C TPerna perna mussel spat were suspended from ropes on a long-line cultivation, at Coqueiro´s Beach, Anchieta, South-eastern Brazil, in order to quantify the fouling community structure and its effects on growth and biomass of mussels. Half of the ropes had the fouling removed monthly, half had the fouling left until the end of the experiment. Monthly samples of thirty mussels from each group were measured and their biomass determined. The fouling organisms were identified, quantified and their biomass evaluated on a monthly basis. After ten months, mussels on the cleaned treatment were significantly larger and heavier (ANOVA; P < 0.05; Bonferroni: unfouled > fouled), showing that fouling reduced mussel development. The most abundant epibiont organisms in terms of biomass were the algae Polysiphonia subtilissima (29%) and Ulva rigida (10.3%), followed by the bryozoans Bugula neritina (13.6%) and Perna perna spat (10.6%). Over 97 taxa and 42,646 individuals were identified, crustaceans being the most abundant group, predominantly one amphipod Cheiriphotis megacheles (12,980 ind.). Species abundance was positively correlated with algal biomass, revealing the influence of algae on vagile fauna, which provide both food and shelter. The benefits of fouling removal are discussed because the majority of species are important feeding items to fishes and yet, the costs of its fouling control added to the associated mussel spat loss make this fouling removal of questionable value. R E S U M OSementes de Perna perna foram colocadas em cordas suspensas em long-line na Praia do Coqueiro, Anchieta, ES, objetivando-se determinar a estrutura da comunidade de incrustantes e seu efeito sobre o desenvolvimento dos mexilhões. Metade das cordas teve os incrustantes removidos mensalmente, na outra metade eles foram deixados até o final do experimento. Mensalmente, 30 mexilhões de cada grupo foram retirados e medidos e a biomassa aferida. Os incrustantes foram identificados, quantificados e a biomassa de cada taxon determinada. Após 10 meses de cultivo, os mexilhões sem incrustantes eram significativamente maiores e mais pesados (ANOVA; P < 0,05; Bonferroni: sem incrustantes > com incrustantes), demonstrando que os incrustantes interferiram negativamente no desenvolvimento dos mexilhões. Os incrustantes mais abundantes em termos de biomassa foram as algas Polysiphonia subtilissima (29%) e Ulva rigida (10,3%), seguidas pelos briozoários Bugula neritina (13,6%) e sementes de Perna perna (10,6%). Foram registrados 97 taxa e 42.646 indivíduos, sendo Crustacea o grupo mais abundante, principalmente o anfípodo Cheiriphotis megacheles (12.980 ind.). A abundância de indivíduos foi positivamente correlacionada com a biomassa de algas, revelando a influência das algas na fauna vágil, provendo abrigo e alimentação. Os benefícios da remoção dos incrustantes são discutidos, uma vez que a maioria dos incrustantes são importantes como itens alimentares para os peixes; além disso, os custos desta remoção somados à perda de sementes de me...

“…Light could influence settlement directly (Williams 1965, Teitelbaum 1966 or indirectly by favouring diatom growth on substrates in the surface waters (Stevenson & Stoermer 1981, Hudon & Boui-get 1983, thus pre-empting space. The high mass of other species, especially mollusks (Table 2), on collectors at 2 and 7 m could also suggest strong intcrspecific space competition (Claereboudt et al 1994), given the fact that in our experiments these were primary space users not colonized by 7. larynx.…”

ABSTRACT. Field observations using settlement panels, which were carried out in Port Daniel Bay, Baie des Chaleurs, Quebec, Canada, in 1992, showed recruitment by the hydi-oid Tubularla laj-ynx to be unevenly distnbuted with depth Multiple regression on residuals indicated that 2 physlcal factors, water temperature and light intensity, out of 5 tested explained 45%) of the observed variance in the recruitment of T. larynx on the panels In laboratory experiments, warm temperatures increased settlement significantly Contrary to held results, light intensity did not seem to influence the settlement of T. larynxin the laboratory The influence of small scale ( < m m ) substrate heterogeneity was also tested in the laboratory Hlghest settlement rates occurred on smooth surfaces, but field experiments carried out in 1993 did not show any heterogeneity preference by T larynx. The influence of extracts and metabolites of conspecific adults on larval settlement was also tested In the laboratory and field Adult extracts had some influence on settlement in some laboratory trials, but not in others In general, T larynx settled more abundantly on surfaces treated with high concentrations of extract solutions than on other surfaces. As was the case for substratum heterogeneity, there was no influence of adult extracts detected In the held In contrast, adult metabolites sholved little influence on settlement under laboratory c o n d~t~o n s and no influence on recruitment in field experiments
