“…Traditional ways of controlling Argulus spp. continue to rely on the use of toxic chemicals and anti-parasitic drugs (Hakalahti-Sirén et al 2008 ; Hemaprasanth et al 2012 ; Raja et al 2022 ). Several chemicals like common salt, potassium permanganate, organophosphate and deltamethrin are commonly in use for the treatment of argulosis (Sahoo et al 2012 ; Das et al 2018a ).…”

Aquaculture and fisheries are salient flourishing sectors in the world but their sustainability is often afflicted by several pathogenic diseases. Among all the pathogenic diseases of fish, parasitic diseases are found to be a major cause of concern. Argulosis is one of the dominant parasitic problems encountered in Indian aquaculture practices. Argulu s siamensis is the most prevalent argulid species harming the Indian major carp species including Labeo rohita. The major carps respond to parasitic infestation by elevating various immune relevant genes. The therapeutic chemicals, synthetic drugs and other plant extracts have made a progress in the fight against argulosis. However, there is no effective vaccine and drugs are available for this disease. Thus, designing efficient, cost-effective and eco-friendly control and treatment strategies for argulosis is presently needed. Keeping the aforementioned facts in mind, the current review elaborated the immunological interaction between A. siamensis and L. rohita , available combat tactics, highlighted the already identified vaccine candidates to design effective control measures and illustrated the use of omics technology in future to combat argulosis.

“…Fish were observed daily for their general behaviour, feeding and mortality. Criteria such as position in water column (e.g., crowding at the water surface; near the outlet or inlet pipe), ashing, gasping, hyperactivity, lethargy, abnormal pigmentation, equilibrium loss, and other uncommon behaviours and/or signs were noted for assessing general sh behaviour (Misganaw and Getu 2016; Ananda Raja et al 2020Raja et al & 2022.…”

“…Lernaea sp. which feeds on the blood, causing mechanical injuries to the host and erosions leading to augmented vulnerability of sh to super-infections, anaemia and death (Wootten et al 1982 Raja et al 2020Raja et al & 2022. Hence identi cation and treatment strategy for such parasitic infestation is paramount important with scienti c and legal regulations.…”

Parasitic infestations and their control programmes are one among the challenges to be considered the most significant in aquaculture. A parasitic infestation was studied elaborately in Asian Seabass, Lates calcarifer juveniles with clinical signs, post-mortem findings, morphological and molecular identifications. In addition, those fish were also treated with emamectin benzoate (EMB) @ 50 µg kg-1 of fish body weight (BW) d-1 for 10 consecutive days under the controlled wet lab facility by feeding through the medicated feed at 4% BW. Results showed that the parasitic prevalence, parasitic intensity (PI) and mortality were 45.5%, 8.17 ± 0.15 per fish and 40% over a period of one week in that existing cage culture. The parasite was identified as a crustacean bloodsucker, anchor worm Lernaea sp. and EMB was found to be 100% effective with significant reduction in PI over a period of 10 days with improved survival rate of 90% against the untreated group. Infested but treated group revealed substantial haematological improvement in parameters such as RBC, WBC, Hb, PCV, large lymphocytes, small lymphocytes and total lymphocytes (P < 0.01). Similarly, comparative histopathology of vital organs also revealed no discernible lesions between the healthy and treated fish juvenile as compared to that of infested untreated group. Hence, EMB can be used to control the Lernaea sp. infestation in Asian Seabass.
