Application of Probiotics for Organic Matter and Enhancement of Growth Performance in White Shrimp (Litopenaeus vannamei)

Abstract

HighlightsLitopenaeus vannamei has been established as alternative to Penaeus monodon to shrimp farming in several countries.Increased importance of in situ microorganisms both in regulating biogeochemical cycles within the culture environment and in directly affecting shrimp growth and survival.To improve water quality in aquaculture is the application of probiotics and/or enzymes to ponds. AbstractIntensive shrimp farming has raised environmental issues due to aquaculture pollution, which is caused by uneaten feed, feces, organic matter, and toxic compounds (ammonia and H2S). One way to solve this issue is by using probiotics. Thus, this study aimed at investigating the effect of probiotic administration (Pseudomonas sp. and Bacillus sp.) at varying concentrations on total organic matter in the rearing water, feed conversion ratio, feed efficiency, and growth rate of white shrimp (Litopenaeus vannamei). This study used a Completely Randomized Design consisting of four treatments: T0 (without the probiotic supplementations), T1 (probiotics at 106 CFU/ml), T2 (probiotics at 107 CFU/mL), T3 (probiotics at 108 CFU/mL) with three replicates each. The results showed that the administration of probiotics at different concentrations had a significant effect on the total amount of organic matter, feed conversion ratio, feed efficiency, and specific growth rate of white shrimp. Administration of probiotics at a concentration of 107 CFU/ ml had the lowest organic matter in the rearing water, 138 mg /Lt. While probiotic administration at 108 CFU/ ml gave the lowest feed conversion ratio (1.22), the highest feed efficiency (81.57%) and the best growth rate (2.25%/day). This research suggests that the administration of 107-108 CFU/ ml probiotics could be applied to reduce organic content in the rearing water and improve the growth performances of white shrimp.

Dynamics of Physics and Chemistry of Vanamei Shrimp (Litopenaeus vannamei) Pond Water with Semi Biofloc System

“…Total organic matter is a collection of accumulated organic compounds that have undergone a decomposition process and describes the concentration of organic matter in waters in the form of dissolved, suspended and colloidal organic matter. Organic material in ponds comes from an uneaten feed, feces and dead plankton (Jefri et al, 2020).…”

Growth of Vannamei Shrimp (Litopenaeus vannamei) in Intensive Cultivation Systems

“…According to Musa et al (2023), TOM levels in intensive vaname shrimp cultivation should be <90 ppm The maximum level of total organic matter in vaname shrimp ponds is 150 ppm. The main sources of organic material in aquaculture ponds are organic fertilizer, feces, food waste, phytoplankton, zooplankton and benthos, zooplankton and benthos (Jefri et al, 2020). The accumulation of organic material that is appropriate to the pond's carrying capacity has a positive impact, because it can produce nutrients that are beneficial for aquatic organisms.…”

The effect of using different types of fertilizer on plankton abundance and growth rate of backyard shrimp farm

“…The volume of vannamei (Litopenaeus vannamei) production in 2019 was 517,397 tons and experience significantly increase of 120% in 2024 to 1.290.000 tons [1]. The increasing productivity of shrimp culture sector is line with the high intensification of shrimp farming systems which causes the environmental degradation [2,3,4]. Various efforts and innovation have been made, especially through the development of aquaculture technology based on the land characterstics and infrastructure availability and feed efficiency [5,6].…”
