“…Polychaete worms such as members of the genera Polydora and Boccardia penetrate and excavate shells, causing cavities, burrows, blisters and tunnels deep within the nacreous layer (Lleonart et al 2003;Silina 2006;Simon et al 2006). The effects are very destructive (Kaehler 1999), with hinge instability, disruption of shell formation, fragility, brittleness and loss of thickness (Mao Che et al 1996).…”

The impact and control of biofouling in marine aquaculture: a review

et al. 2012

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.

“…This species can form dense aggregations of several tens of individuals in one scallop shell (Radashevsky 1993). Sometimes, boreholes of this polychaete can cover the whole of the upper valve of the scallop (Silina 2003(Silina , 2006. This simple association of scallops and polychaete worms provides a convenient model for the study of the inter-specific relationships in communities in the natural environment.…”

“…In certain habitats, only 1-2 species are dominant among such organisms. For instance, in muddy bottom areas of Peter the Great Bay of the Sea of Japan, the shell surface of the benthic mobile Japanese scallop Patinopecten (= Mizuhopecten) yessoensis (Jay) is free of epibionts (Silina 2002), and generally only one species (the boring polychaete Polydora brevipalpa Zachs) occurs in association with the scallop shell (Silina 2003(Silina , 2006.…”

The association between the Japanese scallop Patinopecten yessoensis and the scallopshell-boring polychaete worm Polydora brevipalpa was investigated in the natural environment. Fatty acid analyses were performed on the scallop, polychaete, and potential food materials available in the environment, with the aim of determining the main food sources of these animals and the trophic relationships between species. The scallop and the polychaete showed a similarity in their fatty acid compositions. High concentrations of 20:5n-3 and 14:0, substantial concentrations of 16:2n-4, 16:3n-4, and 16:4n-1, and ratios of 16:1n-7 to 16:0 close to 1 indicated significant contributions of diatoms in the diets of both mollusk and polychaete. Detectable levels of 18:4n-3 suggest that dinoflagellates also contributed to the diet of the animals. The fatty acid markers showed that the scallop and polychaete feed extensively on a mixed, but probably diatom-dominated phytoplankton diet. Additionally, the elevated level of bacterially derived fatty acids and saturated (mainly 18:0) acids in polychaete lipids point to an additional dietary source, detritus and bacteria. Elevated amounts of 22:6n-3 and 18:1n-9 in the scallop digestive gland are indicative of zooplankton consumption. The similarity of the diets is a major determinant of the feeding competition between these species in the community. The decrease in the scallop internal volume concurrent with an increase in the degree of shell occupation by polychaetes suggests a reduction in water-filtering potential by the scallop. Linear regressions of the degree of polychaete occupation against scallop weight and shell height revealed negative relations in both cases. With high levels of shell occupation by polychaetes, the commensal relationship between scallop and polychaete acquires some elements of parasitism.

Coastal zones support fisheries that provide food for humans and feed for animals. The decline of fisheries worldwide has fostered the development of aquaculture. Recent research has shown that extracellular polymeric substances (EPS) synthesized by microorganisms contribute to sustainable aquaculture production, providing feed to the cultured species, removing waste and contributing to the hygiene of closed systems. As ubiquitous components of coastal microbial habitats at the air-seawater and seawater-sediment interfaces as well as of biofilms and microbial aggregates, EPS mediate deleterious processes that affect the performance and productivity of aquaculture facilities, including biofouling of marine cages, bioaccumulation and transport of pollutants. These biomolecules may also contribute to the persistence of harmful algal blooms (HABs) and their impact on cultured species. EPS may also exert a positive influence on aquaculture activity by enhancing the settling of aquaculturally valuable larvae and treating wastes in bioflocculation processes. EPS display properties that may have biotechnological applications in the aquaculture industry as antiviral agents and immunostimulants and as a novel source of antifouling bioproducts.
