Effect of Bacillus subtilis on growth development and survival of larvae Macrobrachium rosenbergii (de Man)

Abstract

A feeding experiment was conducted to investigate the effect of Bacillus subtilis bacterium, on larval growth and development rate of Macrobrachium rosenbergii (de Man) during February 28 to April 8, 2005 in University Putra Malaysia hatchery. Newly hatched larvae of M. rosenbergii were reared with two dietary treatments consisting of newly hatched Artemia salina nauplii with B. subtilis (108 cells ml−1), and newly hatched A. salina nauplii without B. subtilis carried out in triplicate in 60‐L aquarium (50 L−1). After trial, the larvae that fed B. subtilis‐treated Artemia naupli were found to have higher survival and a faster rate of metamorphosis than larvae that were fed with nontreated Artemia naupli. There were significant differences between B. subtilis‐treated Artemia naupli and nontreated Artemia diet in larval growth and development rate of metamorphosis (P < 0.05). Larval survival after 40 days was significantly greater (P < 0.05) in the B. subtilis‐treated groups (55.3 ± 1.02) compared with the nontreated groups (36.2 ± 5.02%).

Effect of Bacillus subtilis on Aeromonas hydrophila infection resistance in juvenile freshwater prawn, Macrobrachium rosenbergii (de Man)

“…These may be attributed to the possibility of higher feed intake and SGR related to treated groups (Keysami et al 2007). The recent reports on the use of Bacillus spp.…”

“…(Rumsey et al 2007), Bacillus sp. (Balcazar et al 2004;Meunpol et al 2003;Keysami et al 2007) and mixed cultures (Sotomayure and Balcazar 2003;Meunpol et al 2003;Salinas et al 2005;Aly et al 2008). The trials demonstrated the growth promotion of fish and crustaceans compared to control groups.…”

“…and Vibrio spp. are among the most important bacterial pathogens of cultured prawns responsible for a number of diseases (Keysami et al 2007). Probiotics have been considered a possible solution to reduce these diseases problems.…”

“…However, the relatively low survival of larval and juvenile stages often prevents the development of full economic potential of this crustacean (New et al 2010). The majority of the freshwater prawn mortality can be attributed to the involvement of pathogenic bacteria (Hoa et al 2000;Scan 2003;Keysami et al 2007). The Aeromonas spp., Enterococcus spp.…”

“…Macey & Coyne (2005), melaporkan penggunaan bakteri probiotik pada budidaya abalon. Penggunaan probiotik pada budidaya udang juga telah banyak dilaporkan, seperti pada budidaya udan g w indu (Meunp ol et al, 2 003;Vaseeharan et al, 2004;Lio-Po et al, 2005;Gunarto et al, 2006aGunarto et al, ,2006bVijayan et al, 2006), budidaya udang Penaeus chinensis (Li et al, 2006), budidaya udang vanamei (udang putih) (Nejad et al, 2006), budidaya udang galah (Keysami et al, 2007), pemeliharaan larva udang (Decamp et al, 2008), dan budidaya udang stylorostris (udang putih) (Castex et al, 2008).…”
