In this work, we examined the effects of rapid changes in salinity on the availability (mobility and swimming) of the prey rotifer Proales similis. Rotifers were transferred as follows: 5 to 15, 25 and 35 (T1); 15 to 5, 25 and 35 (T2); 25 to 5, 15 and 35 (T3) and 35 to 5, 15 and 25 ppt (T4) during 1-240 min. Results showed that in T2 and T3, the percentage of mobile rotifers in the water column recovered up to 100% after 15 min. At T1 and T4, mobility regained slower at 35 and 5 ppt respectively. All individuals transferred at 15 and 25 ppt maintained their mobility above 93% after 15 min. In general, swimming speed ranged from 0.37 to 0.65 mm s −1 and was higher at 15 ppt and lower at 35 ppt. In all salinities, swimming increased with time and recovered better in T2 and T3. These data suggest that P. similis can acclimate to a wide range of salinity gradients in the short term (1-240 min). According to the literature and our results, P. similis has a greater tolerance to sudden salinity changes than brachionid rotifers used traditionally in fish larviculture.

“…Rotifers are among the smallest metazoans with which good results are noted when feeding pikeperch larvae (Yanes-Roca et al 2018, Imentai et al 2019). These organisms have several advantages including their small size, slow swimming, extended suspension time in the water column, rapid reproduction, high autolysis, appropriate protein and energy contents, and non-selective filter feeding behavior (Lubzens 1987, Dumont et al 1995.…”

Pikeperch, Sander lucioperca (L.) is a valuable species that is in high demand among consumers due to its nutritional features such as delicious meat, white and soft texture and lack of intermascualr bones. The main barriers in the development of pikeperch aquaculture are the challenges of its larviculture. A major problem in the larval period is that pikeperch must feed on live food, which imposes high costs on producers. Therefore, substituting live food with formulated diets is necessary, but this process cannot be performed easily and it requires an action plan to be successful. The aim of this study was to provide a brief overview of different aspects related to pikeperch nutrition including its natural feeding habits, nutritional requirements, digestive tract ontogeny, and the most common live foods used in pikeperch first feeding. Moreover, different weaning methods in pikeperch culture are provided to introduce an appropriate strategy to assist this fish in adapting to formulated diets.
