“…Bermudes et al (2010) showed that in barramundi (Lates calcarifer) juveniles, larger fish lost more energy through nitrogen excretion when compared to smaller fish. Dabrowski (1986) commented that fish in the initial phase of development might have higher nutrient requirements to support elevated growth rate compared to fish in later stages of development.…”

“…Although, the concentration of the vitamin C in liver and muscle tissues of experimental diets K, L, Ca, CaL suggests deficiency, neither abnormal fish deformations nor any of the characters common to the above deficiency disease were observed. Dabrowski (1986) reported that the deficiency of ascorbic acid is affected by fish size, feeding duration and previous nutritional status. Ai et al (2006) reported that there was no ascorbic acid in the muscles of yellow croaker (initial body weight, 17.82 g) fed on ascorbic acid free diet, although vitamin C was still detected in its liver (16.6 µg g -1 wet weight).…”

The effects of different forms of vitamin C and soybean lecithin on growth performance, feed utilization and body composition of brown bullhead (Ameiurus nebulosus, Lesuer 1819) were evaluated during a 9-week growth trial. A special interest was to investigate a possible combine effect of these nutritional components. The diets used contained three forms of vitamin C (crystallized ascorbic acid, encapsulated L-ascorbic acid and Ca-L-threonate) (100 mg/kg) with and without the combination of soybean lecithin. Besides control diet (K), one more diet was supplemented with soybean lecithin (L) only. One-hundred-ninety-two brown bullhead of about 45 g initial body weight was randomly divided in 24 tanks (115 L each). Testing conditions included 8 fish per tank, with triplicate tanks for treatment. All diets with supplemented components had higher final weight. Specific growth rate, feed conversion rate and condition factor were significantly higher with encapsulated vitamin C diets (CC, CCL), followed by the results of enriched ascorbic acid diets. Vitamin C and lecithin supplementation showed positive influence on significantly higher number of erythrocytes, haematocrit, triglycerides and total protein. Vitamin C content of muscle and liver tissue was not uniform and was significantly higher in AAL, CCL, CC and AA feeding groups. The fatty acids profile of muscle and liver tissue showed that phospholipids from soybean lecithin and vitamin C diets enhanced the quality of usable part of the fish body. Combine supplementation of vitamin C and soy lecithin indicated positive production effects, but did not cause a statistically significant difference.

“…If vitamin C and size of organism are related, then turnover in fish might be on the order of days to hours, depending on the stage of growth. According to Millikin (1982), Dabrowski (1986) and Soliman et al (1986), the daily requirement of fish (juvenile to adult) is of the order of 1.25 pg g-' of dry diet. Such a quantity could be supplied by 10 to 50 copepods of the size of Calanus helgolandicus.…”

Variation of vitamin C in some common species of marine plankton

Occurrence of vitamin C, observed in 26 species of the major zooplankton taxa, confirms the ubiquity of this essential micronutrient in eukaryotes. Short-and long-term variations of vitamin C in copepods reflected the dependence of vitamin incorporation upon phytoplankton. The link existing between the source of vitamin C, or its precursor, and the rank of the organisms in the marine foodchain is illustrated by the significant difference found between carnivorous and omnivorous/herbivorous species. Copepods and their fecal pellets are substantial carriers of vitamin C, constituting a potential pathway from phytoplankton to consumers in higher trophic levels and probably unable to synthesize this molecule. Information about properties and functions of vitamin C, known for plants and vertebrates, is scant in zooplankton, although it could be relevant to plankton ecology involving feeding, reproduction and growth.
