“…Similary, other investigators have found that astaxanthin is deposited mainly as esters and not free astaxanthin in many crustaceans, particularly during ontogenetic development (Yamada et al 1990, Petit et al 1991, Dall et al 1995, resulting in the predominance (~60 to 90%) of astaxanthin esters in the adults of many crustaceans (Yamaguchi et al 1983, Coral-Hinostroza & Bjerkeng 2002 including calanoid copepods (Foss et al 1987, Juhl et al 1996, Andersson et al 2003 Fig. 4.…”

Zooplankton synthesise astaxanthin, a carotenoid pigment believed to protect against high-energy irradiance, from precursors in their diet. Different patterns of astaxanthin vertical distribution would be expected from the benefits of photoprotection, the costs of visual predation and the availability of food. Despite a highly resolved sampling approach (4 m depth intervals), no clear pattern of vertical distribution or correlation with chlorophyll a concentrations was found for Calanus helgolandicus astaxanthin concentrations in the German Bight. This may be attributable to photochromatic adaptation in phytoplankton, diurnal rhythms of copepod grazing and, particularly, vertical migration. A 2 × 2 factorial (light × food) experiment showed that total astaxanthin concentrations in C. helgolandicus were entirely determined by the dynamics of esterified astaxanthin. As expected, the concentrations of astaxanthin esters decreased in starved individuals in the dark, while the combined presence of food and light resulted in an increase of esterified astaxanthin. Similar levels of esterified astaxanthin were maintained in both starving individuals exposed to light and feeding individuals in the dark. The latter implies that astaxanthin esterification is per se a process independent of light, although light exposure enhances it. It is proposed that the function of astaxanthin esters is to generally improve the antioxidant protection of storage lipids, also in situations where photoprotection is not required.

Penaeid shrimp broodstock nutrition: an updated review on research and development

et al. 2001

View full text Add to dashboard Cite

This paper reviews the current knowledge on shrimp broodstock nutrition with special reference to developments during the last decade. Biochemical studies and diet studies are discussed with the aim of identifying the nutrients that are important to sustain optimal shrimp maturation, reproduction and offspring quality. Additionally, an overview is given of the efforts to reveal the nature of maturation-stimulating factors in fresh food, and of the use and performance of commercial and experimental artificial diets. q

“…Carotenoids have various important biological functions regarding vision (Vershinin 1999), ovarian maturation (Dall et al 1995), reproduction (Gilchrist and Lee 1972) and development (Petit et al 1998;Berticat et al 2000). One of the most common carotenoids in marine invertebrates is astaxanthin, which belongs to the xanthophylls and is usually formed through oxidative transformation from ingested b,b-carotene or zeaxanthin (Katayama et al 1971;Tanaka et al 1976).…”

Pigmentation and spectral absorbance in the deep-sea arctic amphipods Eurythenes gryllus and Anonyx sp.

2010

As for many deep-sea animals, the red colouration of the two amphipods Eurythenes gryllus and Anonyx sp. has an important function providing camouflage, as the attenuation of the red wavelengths in seawater is higher than other colours within the visible range. Variation in colouration between different stages of colour intensity (related to size) is evident in both species. The red colour is caused by carotenoids, and the carotenoid composition was identified and quantified using spectral optical density signatures, high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS). The carotenoid astaxanthin was identified as the major carotenoid in both amphipods, both in pure and in esterified forms. In addition, minor amounts of lutein-like, canthaxanthin-like and several unidentified carotenoids were found in E. gryllus, while diatoxanthin, b,b-carotene and canthaxanthin-like carotenoids were detected in Anonyx sp. Generally, both species displayed an increase in the amount of carotenoids as a function of colour intensity and size. Shifts in k max in the OD (Optical density; dimensionless, acronym absorbance) spectra were evident in both species between the different colour stages in both the in vivo and the in vitro material, probably caused by changes in pigment composition. Similar shifts in k max were observed between the in vivo and in vitro pigment raw extracts in general, most likely caused by pigment-binding proteins. The differences in pigment composition and wavelength shifts suggest large intra-and inter-specific differences between the two species. Probable reasons for changes in pigment composition could be related to diet, season, moulting patterns, metabolic pathways and reproduction.
