Growth of giant tiger prawn, Penaeus monodon Fabricius, under co-culture with a discarded filamentous seaweed, Chaetomorpha ligustica (Kützing) Kützing, at an aquarium-scale

Abstract

Growth of giant tiger prawn, Penaeus monodonFabricius, under co-culture with a discarded filamentous seaweed, Chaetomorpha ligustica (Kü tzing) Kü tzing, at an aquarium-scale Isao Tsutsui AE Poonmanee Kanjanaworakul AE Prapansak Srisapoome AE Dusit Aue-umneoy AE Kaoru Hamano Abstract Growth of juvenile giant tiger prawn, Penaeus monodon Fabricius, was evaluated at an aquarium-scale in co-culture with a discarded filamentous seaweed, Chaetomorpha ligustica (Kützing) Kützing. Juveniles at different ages in days were examined, designated as J 16, J 44, J 58, J 93 and J 128, where a 1-day-old juvenile (J 1) is equivalent to a 20-day-old post-larva (PL 20)). Juveniles at every age group grazed directly on live C. ligustica, even those fed an artificial shrimp diet to satiation. Mean specific growth rate (SGR: % day -1 ) was higher in early age juveniles. Compared to mono-culture, significant differences in growth were observed at J 16 (4.44% day -1 ) and J 44 (1.60% day -1 ); however, no significant differences were recorded at J 58 (1.16% day -1 ), J 93 (0.75% day -1 ) or J 128 (0.45% day -1 ). It was concluded that co-culture of giant tiger prawn with C. ligustica has a dietary advantage, especially in early age juveniles. Age (days)J 16 J 44 J 58 J 93 J 128

Co-culture with Chaetomorpha sp. enhanced growth performance and reduced feed conversion ratio of the giant tiger prawn, Penaeus monodon

“…NA not applicable, SGR specific growth rate, FCR feed conversion ratio specific data) (Limsuwan et al 2008), and Chaetomorpha ligustica increased SGR of giant tiger prawns by up to 157 % at the early juvenile stage (Tsutsui et al 2010). Although direct comparisons with the studies cited above cannot be made because of differences in co-cultured species, our results suggest that the Chaetomorpha sp.…”

“…can reduce artificial feed expenses as efficiently as Ulva species. This is the first report of FCR reduction for a farmed species by the genus Chaetomorpha under coculture conditions, as previous reports have only described improvement in shrimp growth (Tsutsui et al 2010).…”

“…Integrated aquaculture of brackish water prawns or freshwater herbivorous fish from tropical zones with species from the genus Ulva has resulted in increased growth of aquaculture species (Limsuwan et al 2008;Cruz-Suárez et al 2010;Gamboa-Delgado et al 2011;Siddik and Anh 2015). Although other filamentous green seaweeds including Chaetomorpha and Cladophora may be as easily applied in intensive aquaculture systems as Ulva species because of their euryhalinity, so far only few studies have investigated their application as raw feed for aquaculture species (Tsutsui et al 2010). …”

Effects of two commercial feeds with high and low crude protein content on the performance of white shrimp Litopenaeus vannamei raised in an integrated biofloc system with the seaweed Gracilaria birdiae

“…Water was drained from all the samples, the material was carefully inspected to eliminate encrusted organisms and then weighed. Seaweed with reproductive structures, signs of depigmentation and necrosis were discarded (Tsutsui et al, 2010;MarinhoSoriano et al, 2011). Experimental units were stocked with 2.5 kg wet weight of seaweed per cubic meter.…”

High tolerance of Chaetomorpha sp. to salinity and water temperature enables survival and growth in stagnant waters of central Thailand

“…Although it is generally recognized that green tide is negative (Caffrey and Monahan 1999;Lehvo and Bäck 2001;Hiraoka et al 2004;McAvoy and Klug 2005;Morand and Merceron 2005;Liu et al 2009Liu et al , 2013Yamochi 2013), a part of green tide component seaweeds have positive aspects both ecologically and socially (Ohno 1993;Tsutsui et al 2005Tsutsui et al , 2010Tsutsui et al , 2012Bolton et al 2009;de Paula Silva et al 2008;Cruz-Suárez et al 2010;Maceiras et al 2011). For example, several species of Chaetomorpha were started to investigated for their applicability in integrated aquaculture with marine animals (de Paula Silva et al 2008;Tsutsui et al 2010).…”
