Effect of zinc and manganese supplementation in Artemia on growth and vertebral deformity in red sea bream (Pagrus major) larvae

The interactive effect of cobalt enrichment in Artemia on the survival and larval growth of barramundi, Lates calcarifer

“…Standard lengths and wet weights of barramundi larvae were significantly increased in groups where Mn supplemented Artemia were fed. These data confirm previously reported results of Nguyen et al (2008) as they stated that the Mn supplementation to Artemia nauplii significantly improved the growing performance of red sea bream larvae. The supplemented Mn concentration and therefore the dry-matter basis Mn level of barramundi larvae of 30 dph were higher in our study (Mn-1: 0.14 ± 0.07 mg g −1 ; Mn-2: 0.18 ± 0.06 mg g −1 ) than the requirement range for fish reviewed by Watanabe et al (1997) Thus, the current experiments proved that significantly higher concentration of MnCl 2 had no adverse effect on the growing performance of barramundi larvae since best growth was achieved in groups where 100 mg L −1 MnCl 2 supplemented Artemia was applied.…”

“…It was reported for red sea bream (Pagrus major) larvae, that Zn and Mn neither alone, nor in combination affected the survival when fed through enriched Artemia nauplii and it was concluded that the mortality in experimental groups was the result of cannibalism (Nguyen et al, 2008). In our study the survival did not differ significantly from the control in the Co-1, Co-2, Mn-1, Mn-2, CoZn-1 and CoZn-2 groups.…”

“…Enrichment of Artemia nauplii with Co, Zn and Mn 2.1.1. Experimental design Newly hatched Artemia nauplii (Sera, Germany) were enriched for 24 h in a similar manner to a previously described method (Nguyen et al, 2008) with cobalt chloride, zinc sulfate and manganese chloride (CoCl 2 , ZnSO 3 , MnCl 2 AnalaR NORMAPUR, VWR). A total of nine treatments were set in plastic tanks of 4 L at a density of 100-150 nauplii mL −1 .…”

“…Limited data exists exploring Co supplementation combined with Zn and manganese (Mn), although both minerals are vital for optimal growth and accordingly are investigated and applied diet supplements in fish rearing (Lall, 2002;Ovesen et al, 2001;Yamaguchi and Fukagawa, 2005). Zn and Mn are both necessary for the skeletal development, hence supplementation for fish in the early growing stage is important to prevent structural deformities (Nguyen et al, 2008).…”

The Development of Analytical Methods for the Elemental Determination of Biotic Indicators Present in Aquatic Ecosystems

“…Other papers mention seawater or tap water depending on the rearing media [12][13][14], however it can contaminate the samples; while not rinsing the zooplankton organisms at all can result in a positive measurement error. According to our results in the first round of rinsing the collected solutions enriched Fe and Mn in a relatively large concentration.…”
