FEED TIME AND QUANTITY MANAGEMENT IN INCREASE GROWTH RATE AND SURVIVAL RATE OF SNAKEHEAD FISH FARMING, Channa striata (Bloch, 1793)

Abstract

<jats:p>The nature of cannibalism in snakehead fish (Channa stiata) causes high mortality in snakehead fish farming. Good and proper management is needed to minimize its cannibalism. The aims of this research were intended to find out the feeding frequency and feeding rate in growth performance and survival rate of snakehead fish seed. This research was conducted with Factorial Completely Randomized Design (FCRD), which consisted of 2 factors, feeding rate and feeding frequency each with triplicates. The treatments of feeding rate were 3%, 5%, and 7% and the treatments of feeding frequency were 3 and 4 times everyday. The used feed is commercial feed PF-800. The result of this research indicated that feeding rate 7% with 4 times feeding frequency each day was the highest absolute weight and length of growth rate than the other treatments. The highest value in survival rate parameter was feeding rate 3% with 3 and 4 times/day. On the other hand, the lowest value in FCR parameter was feeding rate 5% with 3 times feeding frequency each day. Meanwhile, the highest value in protein retention parameter was feeding rate 5% with 3 times/day. The result showed that there was any interaction in absolute weight of growth rate and protein retention. The single factor in form of feeding rate gave significant results of survival value and feed conversion ratio. The result of this research showed that feed management of 7% FR with 4 times/day FF gave the best result in growth, FCR, and protein efficiency of snakehead fish. Although, it has the lowest SR value, but 7% FR with 4 times/day FF can produce the highest biomass of snakehead fish in this study reached 114,45g.</jats:p>

PENGARUH TINGKAT PEMBERIAN PAKAN BERBEDA TERHADAP LAJU PERTUMBUHAN IKAN NILEM (Osteochilus hasselti) YANG DIPELIHARA PADA SISTEM BIOFLOK RASIO C/N 20

“…Diduga peningkatan laju pertumbuhan bobot ikan Nilem terjadi karena jumlah dosis pakan yang diberi berbeda sehingga semakin banyak jumlah dosis pakan maka semakin tinggi tingkat pertumbuhan ikan Nilem. Hasil ini sejalan dengan penelitian ikan Gabus (Akbar et al 2020) 6,5-9 DO (mg/L) 5,0-8,0 5,0-8,0 5,0-8,0 5 mg/L Amonia Total (mg/L) 0,00014-0,04 0,0014-0,04 0,0014-0,02 0-<0,025 CO2 (mg/L) 2,0-10,0 2,0-9,0 2,0-10,0 5-8…”

Water and land efficiency in eel (Anguilla bicolor bicolor) rearing in development of urban aquaculture through vertical aquaculture system

“…Low water needs increase feed consumption (FC), the rise of FC directly affects growth, the food eaten will be metabolized, and the main nutrient content is absorbed by fish to be stored as growth energy. The high growth of fish will be achieved if the stored energy is greater than the energy used for body activities (37,38). In addition, the quality of the feed given in this study was classified as very good, thereby reducing FCR and increasing growth.…”
