Assessing the Influence of Dietary Pediococcus acidilactici Probiotic Supplementation in the Feed of European Sea Bass (Dicentrarchus labrax L.) (Linnaeus, 1758) on Farm Water Quality, Growth, Feed Utilization, Survival Rate, Body Composition, Blood Biochemical Parameters, and Intestinal Histology

Abstract

The probiotics are being used as ecofriendly and bioremediation tools for developing sustainability to aquaculture. The present study was conducted to explore the practical capability of using dietary lactic acid bacteria (Pediococcus acidilactici) probiotics and see how its dose variation affected the water quality, growth performance, survival rate, body composition, blood biochemical parameters, and intestinal histology of European sea bass (Dicentrarchus labrax L.). A total of 120 fingerlings with an initial weight of 9 ± 0.2 g were divided into four groups, each with three replicates. The feeding experiment lasted for 60 days. In addition to the control (without probiotics) (T0), fish were fed diets containing (T1) 2.0, (T2) 2.5, and (T3) 3.0 g of probiotics per kg of diet twice a day. When compared to the control, sea bass fed probiotic-supplemented diets had significantly higher growth parameters, fish body “crude lipid,” and villi height ( p < 0.05 , p < 0.01 , and p < 0.001 ). The P. acidilactici probiotic treatments improved survival rate, feed conversion ratio, body composition, and blood biochemical markers, but not statistically significant ( p > 0.05 ). Also, in regard to water quality, P. acidilactici drastically reduced ammonia and pH levels. In this experiment, fish fed with a dosage of 3.0 g of this commercial probiotic per kg of probiotics performed better. The study found that including probiotics in the diets of European sea bass improved growth, body composition, survival rate, blood biochemical markers, intestinal histology, and some water quality parameters.

“…Dietary probiotics are considered as a bioremediation and environmental friendly tool for the aquaculture development and sustainability (Ahmad et al, 2017; Eissa et al, 2022; Zibiene & Zibas, 2019), as they have proven to be a great substitute for antibiotics developing the beneficial microflora in the digestive truck of the fish (Huerta‐Rábago et al, 2019; Kavitha et al, 2018; Mamun et al, 2019; Munir, Terence, et al, 2018; Wang et al, 2020). Therefore, fish fed with dietary probiotic supplement exhibited the enhancement of growth performance and health status of several studied fishes like Malaysian mahseer (Sharifah Lia et al, 2022), Asian snakehead (Munir, Roshada, Abdul‐Manaf, & Azizah, 2016; Munir, Roshada, et al, 2018; Munir, Roshada, Yam, et al, 2016; Munir, Terence, et al, 2018; Talpur et al, 2014), common carp and grass carp (Sahandi et al, 2012), tilapia fish (Mohamed et al, 2013).…”

Effects of Dietary Pediococcus acidilactici and Isomaltooligosaccharide on Growth Performance, Immunity, and Antioxidant Defense in Juvenile Common Carp

“…There is a lot of research reporting the positive effects of PA alone or in combination with prebiotics on growth performance and nutrition indices in different fish species [ 7 , 30 , 31 ]. European sea bass fed dietary PA as a probiotic had significantly higher growth parameters and villus height compared to the control [ 32 ]. Besides, probiotics alter the bacterial community in support of improved water quality and subsequently fish growth performance [ 33 ].…”
