“…The existence of significant maternal and paternal effects suggests that cleaning behaviour in lumpfish may have a genetic component (Imsland et al . ). Achieving efficient delousing is key for controlling sea‐lice though the use of cleaner fish.…”

“…They feed on most other organisms in approximately the same proportion as their availability, the dominant prey being crustaceans (harpacticoids, calanoids, cladoceroids), which make up to 91% of the diet, followed by molluscs and small fish, including conspecifics (Ingólfsson & Kristjánsson ; Imsland et al . , ). It might be possible to increase delousing efficiency by selecting individuals that have a greater affinity for consuming sea‐lice, and perhaps also by conditioning them prior to deployment.…”

“…The behaviour of lumpfish in cages has been studied via underwater cameras (Imsland et al 2014c;Imsland et al 2016a), and an ethogram has been constructed which identified 14 different behaviours, with and without Atlantic salmon present (Imsland et al 2014c). Although lumpfish spend relatively little time removing lice, it is sufficient to reduce parasite loads significantly.…”

Efficient sea-lice control remains one of the most important challenges for the salmon farming industry. The use of wrasse (Labridae) as cleaner fish offers an alternative to medicines for sea-lice control, but wrasse tend to become inactive in winter. Lumpfish (Cyclopterus lumpus) continue to feed on sea-lice at low temperatures, and commercial production has escalated from thousands of fish in 2010 to well over 30 million juveniles deployed in 2016. However, production still relies on the capture of wild broodstock, which may not be sustainable. To meet global industry needs, lumpfish production needs to increase to reach c. 50 million fish annually and this can only come from aquaculture. We review current production methods and the use of lumpfish in sea cages and identify some of the main challenges and bottlenecks facing lumpfish intensification. Our gap analysis indicates that the areas in most need of research include better control of maturation for year-round production; formulation of appropriate diets; artificial selection of elite lines with desirable traits; and development of vaccines for certified, disease-free juvenile production. The welfare of farmed lumpfish also needs to be better quantified, and more information is needed on optimal densities and tank design. Finally, the risk of farmed lumpfish escaping from net pens needs to be critically assessed, and we argue that it might be beneficial to recover cleaner fish from salmon cages after the production cycle, perhaps using them as broodstock, for export to the Asian food markets or for the production of animal feeds.

The effect of austempering parameters on impact energy of non-alloyed cast iron with nodular graphite was examined. The analysis involved the austenitizing temperature in the range of 830-950°C for the time of 60 min and the austempering temperature in the range of 300-400°C for the time of 8, 16, 32 and 64 min. The value of the impact energy KV was determined. It has been found that the austenitizing temperature and austempering conditions affect the impact energy of ADI. The conducted analytical studies helped to develop a method for the selection of heat treatment parameters to obtain the ausferritic ductile iron with appropriate impact energy KV. The applied machine learning methods included support vector machine, decision trees, artificial neural networks and the method of variational component analysis.
