“…Hosts are usually pelagic and demersal marine teleosts with a preference towards schooling fish, especially those from the family Carangidae. Hosts include smallmouth scad, Alepes apercna Grant, 1987(see Trilles 1976; Indian mackerel, Rastelliger kanagurta Cuvier, 1816 (see Avdeev 1978;Rokicki 1982;Ghani 2003;; blackfin scad, Alepes melanoptera Swainson, 1839 (previously as Atule malam Bleeker, 1851) (see Avdeev 1978); bigeye scad Selar crumenophthalmus Bloch, 1793 (see Rokicki 1982;Bruce 1990;Nagasawa and Petchsupa 2009;Neeraja et al 2014;Cruz-Lacierda and Nagasawa 2017;present study); Herklotsichthys sp.

“…Since the redescription of N. indica in 1990, records of this species from the Indian subcontinent have mainly been made due to the collection of its fish hosts for subsistence and commercial use by local fisherman. Many of its host species, including Selar crumenophthalmus and Decapterus kurroides, are considered to be commercially important fish species (Argente et al 2014;Cruz-Lacierda and Nagasawa 2017). Other publications from this region provided new host or locality information on N. indica as well as some ecological data including prevalence, mean intensity and abundance (Neeraja et al 2014;Behera et al 2016;Jithin et al 2016).…”

Redescription and molecular characterisation of the fish parasitic isopodNorileca indica(Milne Edwards, 1840) (Crustacea: Isopoda: Cymothoidae) with a key to the genus

Norileca indica (Milne Edwards , 1840) is fully redescribed based on ovigerous females collected from Maputo Bay, Mozambique, from the branchial cavity of the fish host Selar crumenophthalmus Bloch, 1793. An identification key to the species of Norileca Bruce, 1990 is given. Furthermore, a fragment of the mitochondrial cytochrome oxidase I (COI) gene from N. indica was sequenced for the first time. This is the first molecular characterisation of a species of Norileca.

“…In Thailand, this parasitic isopod was reported only in Selar crumenophthalmus [38,72]. N. indica was reportedly found in Alepes apercna, Carangoides malabaricus, Decapterus russelli, Herklotichthyes sp., Nemipterus randalli, Rastrelliger kanagurta, Secutor insidiator, Selar crumenophthalmus [5,14,23,39,42,[74][75][76][77][78][79][80]. These isopods are distributed in the Australia-New Zealand region, the Bay of Bengal, India, Malaysia, Mozambique, Pakistan, the Philippines and Thailand [5,14,23,39,43,[74][75][76][77][78][79][80].…”

From a total of 4140 marine fishes examined, eight species of parasitic isopods were reported from marine fishes in the Gulf of Thailand. These isopods were identified in two families, Corallanidae (Argathona macronema and Argathona rhinoceros) and Cymothoidae (Cymothoa eremita, Cymothoa elegans, Smenispa irregularis, Nerocila sundaica, Norileca indica and Norileca triangulata). Most of these parasitic isopods were found in the buccal cavity of their fish hosts with one host recorded as follows: C. eremita was found from Nemipterus hexodon, C. elegans was found from Scatophagus argus, N. sundaica was found from Saurida tumbil. The majority of the isopod specimens recorded in this study was S. irregularis, which was found in the buccal cavities of five host fish, Pampus argentius, Alepes melanoptera, Caranx hippos, Parastromateus niger and Terapon jarbua, with a prevalence of 11.67%, 10.43%, 9.78%, 6.10% and 4.21%, respectively. Argathona rhinoceros was found in the nasal cavity and branchial cavity of Epinephelus coioides, whereas A. macronema and N. triangulata were found on the skin of Epinephelus coioides and Seriolina nigrofasciata, respectively. The highest species diversity was found in E. coioides, which harbored two species of parasitic isopods, A. macronema and A. rhinoceros. Cymothoa eremita, C. elegans, S. irregularis and N. triangulata were recorded for the first time in the Gulf of Thailand. The reported discovery of C. eremita, S. irregularis, N. sundaica and N. triangulata in their fish hosts were new recorded hosts. Moreover, A. macronema and N. triangulata were found for the first time in the central Indo-Pacific region.

“…The body concentration of salt inside this fish is lower than the surrounding water; thus, it requires them to continuously drink water making the gastrointestinal tract over-exposed to waterborne infections [ 14 ]. Infected fish show common symptoms such as loss of appetite, hemorrhages, lethargy, and mortality [ 15 , 16 , 17 ].…”

Vaccine Efficacy of a Newly Developed Feed-Based Whole-Cell Polyvalent Vaccine against Vibriosis, Streptococcosis and Motile Aeromonad Septicemia in Asian Seabass, Lates calcarifer

et al. 2021

Multiple infections of several bacterial species are often observed under natural farm conditions. The infections would cause a much more significant loss compared to a single infectious agent. Vaccination is an essential strategy to prevent diseases in aquaculture, and oral vaccination has been proposed as a promising technique since it requires no handling of the fish and is easy to perform. This research attempts to develop and evaluate a potential feed-based polyvalent vaccine that can be used to treat multiple infections by Vibrios spp., Streptococcus agalactiae, and Aeromonas hydrophila, simultaneously. The oral polyvalent vaccine was prepared by mixing formalin-killed vaccine of V. harveyi, S. agalactiae, and A. hydrophila strains with commercial feed pellet, and palm oil as an adjuvant was added to improve their antigenicity. Thereafter, a vaccinated feed pellet was tested for feed quality analysis in terms of feed stability in water, proximate nutrient analysis, and palatability, safety, and growth performance using Asian seabass, Lates calcarifer as a fish host model. For immune response analysis, a total of 300 Asian seabass juveniles (15.8 ± 2.6 g) were divided into two groups in triplicate. Fish of group 1 were not vaccinated, while group 2 was vaccinated with the feed-based polyvalent vaccine. Vaccinations were carried out on days 0 and 14 with oral administration of the feed containing the bacterin at 5% body weight. Samples of serum for antibody and lysozyme study and the spleen and gut for gene expression analysis were collected at 7-day intervals for 6 weeks. Its efficacy in protecting fish was evaluated in aquarium challenge. Following vaccination by the polyvalent feed-based vaccine, IgM antibody levels showed a significant (p < 0.05) increase in serum against Vibrio harveyi, Aeromonas hydrophila, and Streptococcus agalactiae and reached the peak at week 3, 5, and 6, respectively. The high-stimulated antibody in the serum remained significantly higher than the control (p < 0.05) at the end of the 6 weeks vaccination trial. Not only that, but the serum lysozyme level was also increased significantly at week 4 (p < 0.05) as compared to the control treatment. The immune-related gene, dendritic cells, C3, Chemokine ligand 4 (CCL4), and major histocompatibility complex class I (MHC I) showed significantly higher expression (p < 0.05) after the fish were vaccinated with the oral vaccine. In the aquarium challenge, the vaccine provided a relative percentage survival of 75 ± 7.1%, 80 ± 0.0%, and 80 ± 0.0% after challenge with V. harveyi, A. hydrophila, and S. agalactiae, respectively. Combining our results demonstrate that the feed-based polyvalent vaccine could elicit significant innate and adaptive immunological responses, and this offers an opportunity for a comprehensive immunization against vibriosis, streptococcosis, and motile aeromonad septicemia in Asian seabass, Lates calcarifer. Nevertheless, this newly developed feed-based polyvalent vaccination can be a promising technique for effective and large-scale fish immunization in the aquaculture industry shortly.
