“…Phagocyte cells play a role in killing pathogenic bacteria by producing reactive oxygen through the respiratory burst process (Neumann, Stafford, Barreda, Ainsworth, & Belosevic, ; Uribe, Folch, Enriquez, & Moran, ). Respiratory burst activity increased can affect the increase in free radical production used to fight pathogens (Sugiani, Sukenda, Harris, & Lusiastuti, ). Based on the results obtained, it was shown that the rise in total leukocytes was in line with the increase in phagocyte activity and respiratory burst.…”

“…Based on the results obtained, it was shown that the rise in total leukocytes was in line with the increase in phagocyte activity and respiratory burst. Vaccinated tilapia shows an increase in total leukocytes followed by the rising of phagocytic activity (Hardi et al, ; Sugiani et al, ). Phagocytic activity increase in vaccinated fish can affect the increase in respiratory burst (Harikrishnan & Balasundaram, ).…”

This study aimed to examine the use of Streptococcus agalactiae polyvalent vaccine in tilapia broodstock and the effect of maternal immunity and resistance on their offspring against S. agalactiae strain. The broodstock was injected with polyvalent vaccine of S. agalactiae at a dose of 108 CFU per fish at 2nd gonadal maturity until spawning. Challenge test was carried out on the offspring at the 5, 10, 15 and 20 days after hatching using NK1, N17O, N14G, N3M, N4M strain respectively and combination of them. We observed immunological parameters in broodstock, eggs and larvae and relative per cent survival (RPS) of larvae after challenged with pathogenic S. agalactiae. The results showed that the leukocytes, phagocytic activity, respiratory burst, lysozyme activity and antibody levels of vaccinated broodstock had higher level compared with unvaccinated broodstock. The high level of the lysozyme activity, antibody levels and recombination activating gene 1 (RAG1) were also observed in eggs and larvae from vaccinated broodstock. Larvae produced from vaccinated broodstock when challenged with variety strain of pathogenic S. agalactiae had RPS value more than 50% until 20 days after hatching. In conclusion, polyvalent vaccine of S. agalactiae administrated in the broodstock could enhance immunity in the broodstock and protect their offspring from pathogenic S. agalactiae.

“…[5]. Occasionally, co-infections between A. hydrophila and S. agalactiae in tilapia were also reported [21,22]. Previous studies suggested that co-infections involving viral and bacterial pathogens might aggravate the disease and increase mortality in the affected fish [7,17,23].…”

A high death rate among red hybrid tilapias was observed in a farm in Selangor, Malaysia, in January 2020. The affected fish appeared lethargic, isolated from schooling group, showed loss of appetite, red and haemorrhagic skin, exophthalmia and enlarged gall bladders. Histopathological assessment revealed deformation of kidney tubules, and severe congestion with infiltrations of inflammatory cells in the brains and kidneys. Syncytial cells and intracytoplasmic inclusion bodies were occasionally observed in the liver and brain sections. Tilapia Lake Virus (TiLV), Aeromonas hydrophila and Streptococcus agalactiae were identified in the affected fish, either through isolation or through PCR and sequencing analysis. The phylogenetic tree analysis revealed that the TiLV strain in this study was closely related to the previously reported Malaysian strain that was isolated in 2019. On the other hand, A. hydrophila and S. agalactiae were closer to Algerian and Brazilian strains, respectively. The multiple antibiotic resistance index for A. hydrophila and S. agalactiae was 0.50 and 0.25, respectively. Co-infections of virus and bacteria in cultured tilapia is a new threat for the tilapia industry.

“…D 1305224 BKC) (Maskur, 2013). The combination of two vaccines created from Streptococcus agalactiae dan Aeromonas hydrophila antigens has been developed to improve the efficiency and capability of product against tilapia diseases (Sugiani et al, 2012). Availability of vaccine products for tilapia is an essential factor not only to cope with disease outbreaks but also to improve the quality of tilapia production and replace the use of antibiotics in tilapia culture.…”

This paper discusses the current status of tilapia aquaculture production, historical development based on the production growth, technological advances in genetic improvement and culture system, trade and product development, strategies, and policies in maintaining and improving national production. All data and information used in this manuscript were collected from available publications relating to the past and present status of tilapia cultivation in the country. Nowadays, Indonesia is the second-largest tilapia producer in the world with the contribution of about 25.89% to tilapia global production. In Indonesia, tilapia is the largest production among other cultured species. The annual growth production of tilapia is inccread 11.61% from 2011 to 2018. West Java Provinceis the largest tilapia producer followed by West Sumatra, South Sumatra, and Central Java. In the last six years, most of tilapia production comes from pond culture followed by floating cages, net cages, paddy fields, and pen culture. The success of tilapia culture is much influenced by technological improve in grow-out and genetic improvement of the local varieties. A side of that, trading and global market oriented are also established with various acceptable products. Tilapia aquaculture in Indonesia shows the succsess story of freshwater aquaculture program from nothing before 1990 to be something at present time. To maintain and increase the future production of tilapia, it needs strategies and policies in production and trade. The tilapia program maybe used as a role model for another economic imprortant freshwater species in Indonesia.
