Effect of vitamin E on the quality of egg bonylip barb fish Osteochilus vittatus (Valenciennes, 1842)

Abstract

Bonylip barb Osteochilus vittatus is a local fish species of significant economic value with vast potential in commercial freshwater fish culture. Traditional cultivation methods are currently employed depending on the seeds, although a low hatchery rate is assumed. The purpose of this study, therefore, was to determine the effect of dietary vitamin E on the quality of bonylip barb eggs, with the applied dosage of 0, 125, 250, and 375 mg/kg. Subsequent parameters measured include fecundity, drowned egg percentage, the chemical composition of eggs, and total energy retention. The results showed that several vitamin E doses significantly (P˂0.05) influenced these aforementioned constraints. Furthermore, the application of vitamin E at 375 mg/kg recorded the best dosage to improve egg quality. In addition, the fecundity was estimated at 23.484 grains, and sink egg percentage reached 92.66%, while protein and fat content were 21.43 mg/kg and 27.88%higher compared to the controlled sample. Therefore, It is concluded that the administration of vitamin E in the feed tends to increase egg quality of bonylip barb fish.

Morphoregression and Reproduction Aspect of Bonylip Barb (<I>Osteochilus vitattus</I> Valenciennes, 1842) in Tamblingan Lake, Bali Island

“…The fecundity of bonylip barb in Tamblinan Lake is greater because the length and weight is bigger than the previous research. Several factors that influence fish fecundity are the fish length and weight (Syandri et al, 2013;Rostika et al, 2017), food availability and nutritional content (Muchlisin, 2014;Tarigan et al, 2020), and differences in habitat (Syandri et al, 2015). Bonylip barb in Tamblingan Lake spawned throughout the year; this was evidenced by the constant finding of male and female on gonad maturing every month of observation.…”

“…Some research related to this species in other freshwater ecosystem have discussed about the growth pattern and condition (Jusmaldi et al, 2020a), reproduction aspect (Omar, 2010), growth and reproduction aspect (Rochmatin et al, 2014), genetic variation (Azrita et al, 2014) and fecundity (Syandri et al, 2015;Rostika et al, 2017). There were also some research in laboratoryscale about induced spawning (Muchlisin et al, 2014;Adami et al, 2016), gonadal maturation (Setyaningrum et al, 2017;Habibah et al, 2020), eggs quality (Tarigan et al, 2020), and post larva development (Yusuf et al, 2014). Although research of bolylip barb has been published in many locations and aspects, research about this fish in the freshwater ecosystem in Bali is still rare and the information of bonylip barb from this location is original.…”

Anchovies (Stolephorus sp.) By-product Material as a Fish-feed Ingredient of Seurukan Fish (Osteochilus vittatus): Effect on Growth Performance and Gut Morphology

“…Therefore, the domestication effort of seurukan fish is attracting attention. Several studies related to the domestication effort of seurukan fish have been conducted in recent years, including alternative feed formulations (Yudhistira et al, 2015;Firdaus et al, 2017;Said et al, 2021;), the addition of supplements and enzymes in the feed (Yusnita et al, 2019;Rijal et al, 2020;Zakiah et al, 2020), reproductive performance and spawning (Muchlisin et al, 2014;Tarigan et al, 2020;Madihah et al, 2021), and optimization of stocking density and feeding time (Aryani et al, 2017;Syandri et al,2015).…”

Influence of antioxidants on the growth performance, gonadosomatic index and biochemical properties of gonad and fertilization success in koi carp (Cyprinus carpioL.)

“…It has been reported that some trace elements and vitamins have been linked with brooder development and egg quality (Ibrahim et al, 2018; Tahapari et al, 2019; Tarigan et al, 2020). Diets are often supplemented with vitamins as essential dietary requirements for fish.…”
