Abstract

The concentration of three heavy metals Pb, Cd and Hg ware measured in Bone River, Gorontalo sediment. The heavy metal pollution on sediment in Bone River have not been explored longitudinally. The samples were taken in July 2021 at 8 stations.  The trend of metals ware observed in sediment as PbCdHg. The level of studied metals Cd and Hg did not exceed the safe limit by ANZECC, OSQG LEL and CCME TEL meanwhile Pb was met the limit by by ANZECC. However, the investigated showed that fluctuations due to differences in the characteristics of each location. Contamination factor (CF) and geoaccumulation index (Igeo) demonstrated that the sediment samples were low contamination and lightly polluted. Contamination by heavy metals in the Bone River implies that the conditions are much frightening for the biota and residents around the river.

Abstract

The success of intensive striped catfish (Pangasius hypophthalmus) cultivation requires quality feed that contains not only protein according to fish needs but also a complete essential amino acid profile to support the fish growth. One solution to overcome this problem is done through the addition of lysine in the feed commercial. This study aimed to examine the effect of lysine addition on the efficiency of feed utilization, growth and body composition of striped catfish (P. hypophthalmus). The study consisted of 4 (four) treatments those were with dosages of 0% / kg of feed (A); 0.6% / kg of feed (B); 1.2% / kg of feed (C); and 2.4% / kg of feed (D) of lysine for every kg of feed. The experimental diet in this study was a commercial feed in the form of pellets which was added with the lysine. A fixed feeding rate of 5%/weight of biomass/day was applied at frequency 3 times a day. The experimental fish used were striped catfish fingerling has an average weight of 4.13 0.26 g/individuals. The results showed that the addition 1,2% / kg of lysine to the diet increased SGR, EFU, FCR, PER and protein content of the body composition of striped catfish.Barbarslot adalah salah satu situs resmi slot deposit 5000, 5rb dan depo 5k terbaru dengan beragam permainan terbaik tahun 2025.
