“…Tizkar et al () stated that at high dietary β‐carotene concentrations, unutilized vitamin A can be stored in the liver, resulting in a significant increase in the liver somatic index (LSI). However, we observed the opposing response since fish fed the supplemented diet showed a decrease in the LSI while the condition factor remained unaltered.…”

This study was conducted to investigate the effects of dietary synthetic β‐carotene on growth performance, haematological and immunological parameters, energy reserves and antioxidant status of juvenile fish Piaractus mesopotamicus. Two hundred and ten fish (12.24 ± 2.98 g) were fed with a control extruded feed (CEF) and the same diet supplemented with β‐carotene (BEF) for 90 days. A higher weight gain and specific growth rate were found in fish fed BEF in comparison with those fed CEF. In addition, BEF‐fed fish showed lower liver somatic index and a higher percentage of eosinophils. No statistical differences were found in energy reserves, except for plasma triglycerides which decreased in fish fed with BEF. Regarding oxidative stress markers, decreased activities of antioxidant enzymes were found in intestine and gills of BEF‐fed fish (SOD and GST, respectively). In the liver, both LPO levels and CAT activity decreased in fish fed with BEF. Additionally, lower brain LPO levels without changes in the antioxidant enzymes were observed in BEF‐fed fish. The inclusion of dietary synthetic β‐carotene improved growth and antioxidant status, and had a plasma triglyceride‐lowering effect in juvenile P. mesopotamicus.

“…Furthermore, astaxanthin has a similar function to lipoic acid, which has very strong protection against cytoplasm and cell nucleus, helps vitamin C, and E does their function properly (Ni, 2015). The vitamin E and astaxanthin are absorbed by the intestine and metabolized in the liver and is further stored in the skin as well as gonads during maturation and in muscle tissue during growth (Tizkar et al, 2016).…”

“…Astaxanthin is a natural carotenoid that produces a red color commonly found in yeasts, algae, crustaceans, and predatory fish such as salmon (Tizkar et al, 2016). Although the astaxanthin does not completely convert into vitamin A, astaxanthin intake continues to increase the supply of vitamin A for the body.…”

The quality of white shrimp Litopenaeus vannamei broodstock can be improved through the addition of astaxanthin and vitamin E in the diet. This study aimed to determine the effect of administration of astaxanthin and vitamin E with different doses in the feed on the maturity gonad of prospective Pacific white shrimp broodstock. Supplementation of 0 mg/kg feed astaxanthin + 0 mg/kg feed vitamin E (control/A), 500 mg/kg feed astaxanthin (B), 350 mg/kg feed vitamin E (C), 500 mg/kg feed astaxanthin and 350 mg/kg feed vitamin E (D), and 250 mg/kg feed astaxanthin and 175 mg/kg feed vitamin E (E) were applied in feed formulation. Shrimp was fed 2% of body weight three times daily at 06.00 am, 13.00 pm, and 20.00 pm. The result showed that the optimum dose for survival, specific growth rate and maturity level of Pacific white shrimp broodstock was obtained in the combination of 175 mg/kg vitamin E and 250 mg/kg astaxanthin. The survival of shrimp by that treatment was 100.00±0.00%, specific growth rate 1.07±0.26%/day, the first level of gonad maturity growth was reached at day 14 (19.45±4.81%), the fourth level of gonad maturity was obtained at day 41, spawning rate 33.33±8.33%, fecundity 87,000±2,000 eggs, and hatching rate reached 49.00±1.53%. Keywords: astaxanthin, Litopenaeus vannamei, vitamin E ABSTRAKPeningkatan kualitas induk udang vaname Litopenaeus vannamei dapat dilakukan dengan penambahan vitamin E dan astaxanthin pada pakan. Tujuan penelitian ini adalah untuk mengevaluasi pengaruh pemberian astaxanthin dan vitamin E dengan dosis berbeda dalam pakan terhadap tingkat kematangan gonad calon induk udang vaname. Dosis yang digunakan adalah 0 mg/kg pakan astaxanthin + 0 mg/kg pakan vitamin E (kontrol/A), 500 mg/kg pakan astaxanthin (B), 350 mg/kg pakan vitamin E (C), 500 mg/kg pakan astaxanthin and 350 mg/kg pakan vitamin E (D), and 250 mg/kg pakan astaxanthin and 175 mg/kg pakan vitamin E (E). Pemberian pakan dengan penambahan vitamin E dan astaxanthin dilakukan sebanyak tiga kali, yaitu jam 06.00, 13.00, dan 20.00 WIB sebanyak 2% dari bobot udang. Hasil penelitian menunjukkan bahwa dosis optimum untuk sintasan, laju pertumbuhan spesifik, dan tingkat kematangan induk udang vaname diperoleh dengan kombinasi 175 mg/kg vitamin E dan 250 mg/ kg astaxanthin. Kelangsungan hidup udang dengan perlakuan tersebut adalah 100,00±0,00%, laju pertumbuhan spesifik 1,07±0,26%/hari, tingkat kematangan gonad pertama dicapai pada hari ke 14 (19,45±4,81%), tingkat kematangan gonad keempat diperoleh pada hari ke 41, tingkat pemijahan 33,33±8,33%, fekunditas 87.000±2.000 telur, dan tingkat penetasan mencapai 49,00±1,53%.Kata kunci: astaxanthin, udang vaname Litopenaeus vannamei, vitamin E

The experiment was conducted to evaluate the effect of vitamin E on the gonad development of sandfish, Holothuria scabra. Four experimental diets were formulated to contain different levels of vitamin E, i.e. 0, 150, 300, and 450 mg/kg diet. Dry diets were prepared at the same protein level (14%). The experiment was arranged in a completely randomized design with four treatments and three replicates. Before the experiment started, the internal organs of broodstock were removed (evisceration) by injecting KCl 1 N reagent into their body, and the gonads were observed to determine the sex of each broodstock. Mean total length and body weight of broodstock after the internal organ removal were 10.95 ± 0.37 cm and 61.12 ± 2.28 g, respectively. Three broodstock (one male and two females) were allocated into each plastic bucket with a volume of 150 L. Each plastic bucket was equipped with aeration and flow-through water system. Broodstock fed with experimental diet once daily at 3% of total biomass for 90 days. The results showed that vitamin E has significant effects on percentage of gonad maturation stages and gonad somatic index (GSI) (P<0.05). Vitamin E at 300 mg/kg diet was the best for gonad maturation of sandfish broodstock. Furthermore, 55.5% and 11.1% of broodstock fed a diet containing 300 mg vitamin E/kg diet reached gonad maturity stage-III and stage-IV, respectively, with GSI of 12.21%.
