“…A solution was prepared containing fresh water and tricaine methane-sulfonate (MS-222) (Sigma-Aldrich) (50 mg/L) to anaesthetize the fish and reduce handling stress. The freshwater medium was used as an anesthetic to reduce the stress as well as for easy handling [6,7]. After the fish had been anaesthetized, parasites were collected from the external skin surfaces of infested areas of the fish such as the head, body and both sides of the inner operculum using surgical dissecting forceps [6,7].…”

Fish parasites such as Caligus clemensi are a serious concern for cultured fish in many regions of the world, including Malaysia. This study was designed to elucidate the parasites’ prevalence and intensity coupled with the morphology and molecular identification of C. clemensi on cultured Lutjanus erythropterus in Jerejak Island, Penang, Peninsular Malaysia. The study was carried out on 200 fish specimens of cultured L. erythropterus obtained from the GST group aquaculture farm. Parasites were collected from the infested part of L. erythropterus fish, and their prevalence and intensity were determined. The parasites were identified morphologically using a field emission scanning electron microscope. Molecular studies were performed through PCR amplification and sequencing. MEGA 5 was used to construct a phylogenetic tree using the pairwise distance method. The results showed that only the C. clemensi parasite was found prevalent on L. erythropterus fish with a prevalence and mean intensity (S.D) of 198 (99%) and 36.4 ± 12.2, respectively. The prevalence varied significantly with respect to fish length (p < 0.05). The nucleotide BLAST sequence for 18S ribosomal RNA partial sequences showed 97% with 100% query similarity, E-value 0 with C. clemensi with the accession number DQ123833.1. Conclusively, C. clemensi remains a major parasite of L. erythropterus in the study area.

“…Given this, nonpharmacological interventions are preferable for disease management in terms of both animal welfare and sustainability (Lieke et al 2020). For example, nano-filtered, hyposaline water is effective against sea lice and AGD, demonstrating the feasibility of more sustainable and welfare-friendly treatments (Mc Dermott et al 2021).…”

With the increasingly global scale and scope of aquaculture, the need to match this development with improvements in fish welfare is a central societal and industry goal. We provide a comprehensive assessment of the farmed Atlantic salmon (Salmo salar) literature with targeted examples focusing on Atlantic salmon farmed in Tasmania, Australia. We synthesise insights from both small- and industry-scale perspectives, highlighting other reviews that provide discussions of particular sub-areas of farmed salmon research. We focus on recent advances and improved methods for farmed Atlantic salmon handling and management, behaviour, health issues and breeding. We also address wildlife interactions resulting from fish farming, as well as future research directions and system development. This review can serve as the basis for the development of aquaculture management guidelines that place individual fish welfare as a primary goal.

“…Sea lice management in salmon farms involves applying different techniques to control the abundance of the parasite and to mitigate the impact on the livestock. Among the different existing approaches to delouse the salmon are: (a) administration of veterinary medicines, either topically or in-feed; (b) cleaner fishes, such as the lumpfish Cyclopterus lumpus (Imsland et al, 2014) provide positive effects as part of a sea lice management plan; (c) filtration methods have also proven to be an efficient method for removing all stages of sea lice (O'Donohoe and McDermott, 2014); (d) thermal and hyposaline treatments control sea lice numbers on salmon farms in the West of Ireland, especially during the summer months (McDermott et al, 2021).…”
