| dc.description | opment for microbial control strategies since disease outbreaks are recognized as important constrains to aquaculture [1].One of the methods gaining recognition for controlling pathogens within the aquaculture industry is the use of beneficial or probiotics bacteria [1,2,3]. The use of antibiotic to treat or control disease in aquaculture has been reported to disrupt the fish intestinal microflora [4] pollute the environment, increase cost of production and ultimately cause prevalence of antibiotic resistance [4]. To keep a sustainable growth pattern and health management, strategies must go beyond antibiotics and chemotherapeutics, which create resistant bacteria and immunosuppression in the host [5]. The antibiotic resistant bacteria have been reported to be capable of proliferating after an antibiotic has killed off the other bacteria and they can also transfer their resistance genes to other bacteria that have never been exposed to antibiotic [2]. Resistance mechanism can arise in one of these two ways: chromosomal mutation or acquisition of plasmids. Several bacteria pathogens can develop plasmid mediated resistance. At the high population densities of bacteria found in aquaculture ponds, transfer via viruses and even direct transformation from DNA observed to the particles in water or on sediment surface could all be likely mechanism of genetic exchange [6] In view of the above, the development of non-antibiotic agent is one of the key factors for health management in aquaculture. One of the most significant technologies that evolved in response to disease control problem is the use of probiotics. The application of probiotics is prevalent in United State of America, China, Japan, Indonesia, Thailand and European countries with commendable achievements. However, although the Nigeria aquaculture industry is expanding the application and development of probiotics is very meagre when compared to other countries. This study was primarily carried out to investigate the growth performance of C. gariepinus fed L. acidophilus supplemented feed for 90 days | |
| dc.description.abstract | The aim of this work was to evaluate the usefulness of Lactobacillus acidophilus as a potential probiotic in fish farming using C. gariepinus as biological model. The experimental fish were divided into four groups, the first group was fed on diet supplemented with 0.5ml of L. acidophilusand designated as Group A ,the second group was fed on diet supplemented with 1 ml of L. acidophilusand designated as Group B the third group was fed on diet supplemented with 1.5ml of L. acidophilusand designated as Group C and the fourth group was served as control fed on L. acidophilus-free diet. The final weight of the groups that received L. acidophilus were not statistically different with the following mean values 390g, 395g and 400g for Group A ,B and C respectively but the mean weight of the control that does not receive L. acidophilus was 350g which is statistically different from the groups that received L. acidophilus. The result obtained revealed that percentage of fish that survived in the groups fed with L. acidophilus were 84%, 88% and 88% for Group A ,B and C respectively and 72% for the control that was not fed with L. acidophilus the corresponding percentage mortality was calculated to be 16%, 12%,12% and 20 % respectively. The result indicated that percentage mortality was very high in the control group that was not fed with L. acidophilus.This study was able to establish that L. acidophilus could be a good probiotic candidate in fish production because of its ability to enhance growth of C. gariepinus. | |
