“…Herbivorous fish may derive their pigments directly from autotrophs (Choat and Clements, 1998) and freshwater Cyprinidae fish can synthesize (3S,3 ′ S)-astaxanthin from zeaxanthin by oxidative metabolic conversion (Liaaen-Jensen, 1998;Schiedt, 1998;Matsuno, 2001). Nevertheless, fish generally feed on a variety of food items and obtain carotenoids from their heterotrophic prey.…”

Carotenoids in Aquatic Ecosystems and Aquaculture: A Colorful Business with Implications for Human Health

The colorful carotenoid pigments are known as biological active compounds that have beneficial effects on the metabolism of animals and humans. Carotenoids provide protection against several stressors, including UV radiation, reactive oxygen species and free radicals, have important roles in vision, and act as precursors of transcription regulators and in the immune system. Studies on human nutrition point to the relevance of consuming functional foods instead of supplementing the human diet with the desired nutrients. This stresses the importance of obtaining dietary items with high quality nutritional value for human consumption. The various biological roles of carotenoids in aquatic animals ascribes them a major role in aquaculture where they are routinely added to ensure the development and health of fish such as salmon, trout and red porgy, and of shellfish like shrimp and lobster. In aquaculture, it is widely recognized that fish larvae dramatically increase their survival rate when reared on live feeds (e.g., rotifers, Artemia sp. and copepods) containing carotenoids. Ultimately, pigmentation provided by carotenoids is one of the relevant quality attributes of the aquatic animal for consumer acceptability and market value. Appropriate feeds for aquaculture are thus required to provide the carotenoids necessary for the desired pigmentation. In this review, we discuss the role of carotenoids in aquatic food webs, both in the wild and in aquaculture, and its relevance for human health.

“…In contrast to the broad knowledge base that exists on the mechanisms required to process nutrients as well as mechanisms used by domestic and laboratory species to metabolize drugs, there is a general lack of understanding of how PSMs are processed by herbivores, especially in the context of a variable nutrient environment (Appel, 1993;Casarett et al, 2008;Gross and Bakker, 2012;Karasov and Hume, 1997). The gap in knowledge related to mechanisms required to process nutrients in marine herbivorous fishes, for example, has only recently begun to close (Choat and Clements, 1998;Clements et al, 2009). Moreover, despite a long history of investigating how aquatic animals process chemical contaminants (Chambers and Yarbrough, 1976;Katagi, 2010;Rewitz et al, 2006;Smital et al, 2004), studies investigating how they process dietary secondary metabolites have only recently been initiated (Gross and Bakker, 2012;Liang et al, 2007;Richardson et al, 2009).…”

“…For several decades now, a central focus in the field of nutritional ecology has been to understand the factors that influence the foraging behavior of terrestrial and aquatic herbivores (Choat and Clements, 1998;Clements et al, 2009;Dearing et al, 2005;Foley et al, 1999;Scriber and Slansky, 1981). There is ample evidence from each of these areas that the foraging behavior of herbivores is driven by both nutrients and chemical defenses.…”

A Pharm-Ecological Perspective of Terrestrial and Aquatic Plant-Herbivore Interactions

et al. 2013

-We describe some recent themes in the nutritional and chemical ecology of herbivores and the importance of a broad pharmacological view of plant nutrients and chemical defenses that we integrate as "Pharm-ecology". The central role that dose, concentration, and response to plant components (nutrients and secondary metabolites) play in herbivore foraging behavior argues for broader application of approaches derived from pharmacology to both terrestrial and aquatic plant-herbivore systems. We describe how concepts of pharmacokinetics and pharmacodynamics are used to better understand the foraging phenotype of herbivores relative to nutrient and secondary metabolites in food. Implementing these concepts into the field remains a challenge but new modeling approaches that emphasize tradeoffs and the properties of individual animals show promise. Throughout we highlight similarities and differences between the historic and future applications of pharm-ecological concepts in understanding the ecology and evolution of terrestrial and aquatic interactions between herbivores and plants. We offer several pharm-ecology related questions and hypotheses that could strengthen our understanding of the nutritional and chemical factors that modulate foraging behavior of herbivores across terrestrial and aquatic systems.

“…The adoption of same antibiotics in different fields improves the emergence and occurrence of the resistance phenomenon. Some bacterial fish pathogens are also associated to diseases in humans, making the aquaculture products a potential risk to the customers (Choat and Clement, 2008;Saranraj and Geetha, 2012). Many organisms were found in fish from polluted warm waters.…”

Microorganisms are found on all surfaces and in the intestines of live fish or preserved fish. Microbial flora of fish on the fishing depends on the environment in which it was caught more than fish species. Fish fishing in clear water and very cold, carries a small number of microorganisms compared with fish from the warm water which has a number of microorganisms a little higher. In this study, an attempt was made to isolate and identify the bacteria and fungi present in the preserved Yellow goat fish (Sulphureus cuvier). The fish sample was collected from Kanchipuram fish market, Tamil Nadu, India. Isolation of bacteria and fungi was carried out by Pour plate method (Serial dilution technique). The bacterial isolates were identified based on the Staining techniques, Platting in Selective medium and Biochemical tests. The bacterial isolates were identified as Bacillus cereus, Pseudomonas aeruginosa, Proteus mirabilis, Klebsiella pneumoniae and Escherichia coli. The fungal isolates were identified based on the Lactophenol cottonblue staining techniques and Platting in Sabouraud's dextrose agar medium. The fungal isolates were identified as Aspergillus niger and Aspergillus flavus.
