“…and Skeletonema costatum. Results obtained are in accordance with our previous work concerning the fatty acid composition of plankton at neighboring coastal locations (Silina & Zhukova 2007): plankton samples exhibited high levels of fatty acids characteristic of diatoms, with an elevated input of components specific to dinoflagellates. Phytoplankton was mainly associated with PUFA, while near-bottom POM was associated with significant levels of saturated fatty acids (mainly 16:0, monounsaturated fatty acids, and iso-and anteisobranched fatty acids derived from bacteria and detritus), as well as with PUFA.…”

“…The bivalve digestive gland incorporates a large number of food particles by the process of phagocytosis (Chang et al 1989), and it is suspected that food items including membrane lipids of plankton cells contribute substantially to the fatty acids of this organ. Therefore, the use of total lipids of the digestive gland, rather than TAG, is the most efficient means to trace scallop feeding (Napolitano & Ackman 1993, Silina & Zhukova 2007.…”

“…The presence of only minor amounts of odd and branched fatty acids in the digestive gland of scallops reflected insignificant consumption of bacteria by the mollusk. Even on muddy substrates rich in bacterial fatty acids, the bacterial contribution to the scallop diet was insignificant (Silina & Zhukova 2007). The substantial quantities of fatty acids specific to bacteria in the polychaete suggest that the polychaete ingests decayed material of planktonic origin (abundant in near-bottom water) or free-living bacteria.…”

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.

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 effect of boring worms on oysters, abalones, scallops, clams and mussels have mainly been studied in mariculture conditions. Some researchers have shown that boring worms affect the health and growth of mollusks (Lleonart et al. 2003), whereas others did not find such an effect (Caceres-Martinez & Tinoco-Orta 2001, Calvo et al. 2001, Handley & Bergquist 1997.

“…The fatty acid composition of the animal tissues is closely related to the pattern of fatty acids in the animal's food sources (Howell et al 2003). Fatty acid biomarkers may be used to trace bacteria as the food source for aquaculture animals (Silina & Zhukova 2007). However, because there may exist a discrepancy between the bacterial fatty acid profile and the tissue's fatty acid profile due to other food sources, accurate assimilation efficiency may not be determined.…”

Bacterioplankton is an important component of marine as well as fresh waters and accounts for a large fraction of the production of particulate matter in those ecosystems. The concept of bacteria as providers of essential nutrients in aquatic food webs has been raised most recently in relation to the utilization of bacteria as a food source in aquaculture food chains. This article represents a comprehensive review on the potential role of bacteria as a direct food source for aquaculture organisms. After studying shortly the analytical tools that can be applied to determine the uptake and assimilation of bacteria by higher trophic levels, it describes the bacterial loads that are found in closed and open aquaculture systems and elaborates on the composition of bacteria from a nutritional point of view. Next this study elaborates in more detail on the role of bacteria as food for the zooplankton groups used as live food in aquaculture hatcheries and for various groups of aquaculture target organisms, such as fish, crustaceans and especially bivalves. This includes an assessment of the specific uptake mechanisms of the different taxonomic groups of interest in relation to their efficiency to ingest bacteria. Finally, future research lines are suggested to elucidate the nutritional impact of the bacterial community in aquaculture systems and how to steer this in order to optimize the production.
