Green water technology for the production of pacific white shrimp, Penaeus vannamei (Boone, 1931)

Abstract

Materials and methods Design of experimentThe experiment was conducted in 6 high density polyethylene (HDPE) lined ponds (300 m 2 ) at King Abdulaziz University (KAU) Fish Farm, Faculty of Marine Sciences, Obhur, Jeddah for a period of 96 days. Semi-intensive type of culture method was followed for rearing shrimp. Both control and treatment experimental ponds were triplicated. All ponds were sundried and limed ABSTRACT A study was conducted to assess the efficiency of green water culture strategy for production of Pacific white shrimp Penaeus vannamei (Boone, 1931) in high density polyethylene (HDPE) lined ponds (300 m 2 ) for a period of 96 days. Green water from a broodstock fish pond was used for rearing shrimp in treatment ponds; whereas, filtered seawater was used for growing shrimp in control ponds, with both treatment and control in triplicates. Shrimp juveniles (specific pathogen free, SPF) of uniform size (1.74±0.46 g) were stocked at the rate of 100 nos. m -2 per pond. Feeding, water exchange, sampling and water quality analysis were done as per standard shrimp growout procedure. Shrimp health status and microbial load in culture ponds were recorded periodically. Water quality parameters did not show significant variations between control and treatment ponds. Enhanced growth, survival (19.7%) and biomass (23.3%) were observed in treatment ponds when compared to control. Significant reduction in bacterial population and improved shrimp health status were also noticed in treatment ponds. Green water culture technique reduced harmful bacterial population in culture ponds and enhanced shrimp growth, survival, health and production.

“…According to FAO (2020) production of L. vannamei accounted for 52.9% of crustacean aquaculture in 2018 and rapidly expanded from 2.64 million tons in 2010 to 4.96 million tons in 2018. Technically, the positive trend was also driven by technology, including the breeding technology (Argue et al., 2002; Wang et al., 2019; Xiong et al., 2011), development of biofloc and green water technology (Arantes et al., 2017; Chithambaran et al., 2017), feed management system (Reis et al., 2020; Silva et al., 2019), biosecurity technology (Lightner, 2005; Moss et al., 2012) and raise awareness about sustainability in shrimp production system (Lebel et al., 2010; Lebel et al., 2016). All these technologies and innovations could optimise the seed quality, growth, survival rates and culture environments of L. vannamei , thus reducing uncertainty in the production system.…”

Mutualistic interactions of green microalga Chlorella sp. with bacterial quorum sensing degrader Bacillus spp isolated from biofloc and freswater prawn Macrobrachium rosenbergii

“…There are several methods to control bacterial diseases in aquaculture such as immunostimulants, vaccines, water disinfection, probiotics including green water technique. Green water can also be a potential technique to control diseases where it improves water quality and enhances aquatic organism resistance to diseases (Chithambaran et al, 2017). Furthermore, previous researches have reported that bacteria greatly affect the growth of microalgae (Grossart et al, 2005), because the organic carbon such as dissolved and particulate particles from live and cell lysis of dead microalgae can promote bacterial growth.…”
