“…2). This result shows that VB 12 -free Chlorella had poorer dietary value in comparison with VB 12 -enriched Chlorella as in previous findings 30,31 . Nevertheless if a small amount of Co compound was supplemented to the tanks with VB 12 -free diet, a clear positive lighting effect was observed and a better population growth was obtained in the lighting tanks (Fig.…”

“…In fish, poor appetite, poor growth and poor food conversion were found as VB 12 deficiency symptoms 7 . The physiological function of VB 12 for zooplankton has not yet been studied, but the supplementation of this vitamin to culture water was reported previously to be effective for enhancing reproduction performance of rotifers 8,17,30,31 . From these experimental findings, feed companies supplement it and enrich the contents of this vitamin to enhance the dietary value of their products, in spite of its expensiveness [13][14][15] .…”

“…In aquaculture relevancy, the function of VB 12 for enhancing population growth performance of rotifers was studied and reported previously 8,17,30,31 . Recently we found a cobalt compound (cobalt (II) sulfate heptahydrate: CoSO 4 7H 2 O) supplementation to rotifer feed also effectively enhanced the population growth of the S-type rotifer B. rotundiformis 23 .…”

The effect of lighting to rotifer culture water was investigated preliminarily using freshwater Chlorella as food in terms of vitamin B 12 (VB 12 ) production. The marine rotifer Brachionus plicatilis was batchcultured for five days at 25°C in 25 psu seawater with or without lighting (L:D = 13:11 and L:D = 0:24). Rotifers were fed VB 12 -enriched or VB 12 -free Chlorella vulgaris with or without cobalt compound supplementation (cobalt (II) sulfate heptahydrate: CoSO 4 7H 2 O). When VB 12 -enriched Chlorella was fed, rotifer with lighting showed better population growth than in complete dark. On the other hand, no difference was observed in the population growth between light and dark groups when VB 12 -free Chlorella was used. Nevertheless if the cobalt compound was supplemented to VB 12 -free Chlorella, the light group showed higher population growth than non-supplemented groups and dark groups, and a much higher amount of VB 12 was detected from the tanks than those from other groups. In addition to that, even in the group fed VB 12 -free Chlorella without Co supplementation a daily increase of a small amount of VB 12 was observed when they were lit up. From these experimental results, we can conclude that lighting plays an important role for the population growth of rotifers and Co compound supplementation to rotifer culture water promotes the reproduction performance of rotifers due to the enhanced production of VB 12 by lighting.

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.

“…For instance, Gorospe et al (1996) explained the nutritional contribution of Pseudomonas sp. in Artemia culture as the bacteria being an additional source of protein, and Yu et al (1998) demonstrated that vitamin B12 producing bacteria can be used as a nutritive complement for rotifers Brachionus plicatilis. More globally, probiotics may favour growth by a number of mechanisms, either alone or in interaction, by: (1) increasing the pool of digestive enzymes in the GI tract or stimulation of digestive enzyme production by the host, (2) increasing nutrient availability to the organism for absorption in the GI tract (for example by pre-digesting some elements of the feed), and/or (3) providing additional bacterial biomass which the host can use as an additional nutrient source.…”

Crustacean aquaculture, and more specifically shrimp culture, faces several challenges in order to increase production yield while maintaining sustainability. The various disease outbreaks that have been continuously affecting the sector for almost two decades, together with the increasing demand for environmentally friendly aquaculture and the pressure from customers for safe and traceable products, are fundamentally modifying the culture practices of shrimp and other crustacean species. It is today well accepted that these challenges can only be faced through the development of better management practices together with technical innovations. Among the solutions currently considered, those relying on nutrition and intestinal health management can play a critical role. The application of probiotics in aquaculture has been developed in this context and is now widely applied in crustacean aquaculture as a complementary tool for management of disease. This development is mostly driven by practical and empirical approaches in shrimp farming; however, specific in-depth studies related to the biological effects and mechanisms of action of probiotics in crustaceans are gaining more importance. This chapter presents a review of the research conducted on probiotic applications in crustacean species with special emphasis on the modes of action investigated so far and the main benefits derived from it. The limits and future perspectives are also addressed.
