	abstract = {Pikeperch (Sander lucioperca) has a high potential for inland aquaculture diversification in Europe. Bottlenecks (i.e. low survival, cannibalism and deformity rates) hamper further expansion of pikeperch culture, because of the weak production performances at the nursery level. To improve the production of pikeperch juveniles under recirculation system we used a pilot scale larval rearing system (700 L tanks) and multifactorial designs. Three successive larval rearing trials (duration: 35-49 days) were conducted to identify the best combination of en- vironmental, feeding and population factors. Considering the main significant effects observed on survival, growth, swim bladder inflation rates and biomass gain, a favourable combination of twelve factor (F) modalities was proposed (F1- initial density: 100 larvae.L-1, F2- no sorting of fish jumper, F3- no sibling population, F4- eggs from large females, F5- discontinuous feeding, F6- no co-feeding, F7- light intensity: 50 lx, F8- beginning of the weaning at 16 dph (days post-hatching), F9- weaning duration: 9 days, F10- water renewal rate of 100 \% per hour, F11- tank cleaning during morning and F12- tank bottom-up water current). A final validation step was realized over a last trial (seven replicates, duration: 49 days), and validated with the best productive results obtained over the global experimental period (2015-2018). These results were: a final body weight of 815.64 {\textpm} 95.34 mg, a survival rate of 16.9 {\textpm} 1.7 \%, a specific growth rate of 15.1 {\textpm} 5.9 \%.d-1, a final fish biomass of 9.55{\textpm}0.23 kg, a swim bladder inflation rate of 92.6{\textpm}3.2 \% and a food conversion rate of 0.65 {\textpm} 0.02 (dry food). The final stocking density was 13.6 kg.m-3\&nbsp;of rearing volume. Authors were able to validate and provide a reliable basic protocol for pikeperch larval rearing using recirculating units.},

	abstract = {<p>The aim of the study was to evaluate the influence of different dietary protein and lipid levels and their ratios on larval growth, survival and the incidence of cannibalism in Pseudoplatystoma punctifer. Larvae were raised in a recirculation system from 3 to 26\&nbsp;days post-fertilization (dpf) (2{\textendash}25\&nbsp;days post hatching, dph) at an initial density of 40 larvae L-1, 27.8\&nbsp;{\textpm}\&nbsp;0.65{\textdegree}C and 0L\&nbsp;:\&nbsp;24D photoperiod. Larvae were fed from 4 to 12 dpf with Artemia nauplii and weaned onto four different compound diets from 13 dpf within 3\&nbsp;days, then fed exclusively with these diets until 26 dpf. These diets contained 30\&nbsp;:\&nbsp;15, 30\&nbsp;:\&nbsp;10, 45\&nbsp;:\&nbsp;15 or 45\&nbsp;:\&nbsp;10 protein\&nbsp;:\&nbsp;lipid (P\&nbsp;:\&nbsp;L) (in \% of dry matter) levels. A control group was fed Artemia nauplii until 17 dpf and weaned thereafter with the 45P\&nbsp;:\&nbsp;10L compound diet. The experiment was carried out in triplicate. Results showed higher growth and survival rates and lower incidence of cannibalism in the group fed the 45P\&nbsp;:\&nbsp;15L diet than in the other treatments. Differences in larval survival and growth performance were associated with the higher protein and lipid content rather than the protein\&nbsp;:\&nbsp;lipid ratio of this diet. When comparing diets with the same protein level, the increase in dietary lipid led to an improvement in growth, suggesting that energy from lipids spares protein for growth in P.\&nbsp;punctifer fingerlings. An Artemia feeding period longer than 12 dpf did not improve larval growth or survival.</p>
