Dietary protein requirement of sharpsnout sea bream (Diplodus puntazzo, Cetti 1777) juveniles

Evaluation of Protein Levels in Diets for Salema Porgy (<i>Sarpa salpa</i>) Juveniles, a New Candidate Species for the Mediterranean Aquaculture

“…This condition has also been reported for white seabream [21], in zebra seabream [22], in sharpsnout seabream [24,42], and in Blackfin seabream [31]. The finding in the present study for the feed intake in salema porgy is in agreement with earlier reports, in terms of increased feed intake (p<0.05) with the decrease of protein levels in the diets.…”

“…Similar to the findings in the present study, protein requirements for two-banded seabream (Diplodus vulgaris) were reported between 35-36% in earlier studies [23,30], while a lower protein level of 27% was recorded for juvenile white seabream (Diplodus sargus) [21]. In contrast, higher protein levels for best growth were found for other sparids such as Blackfin seabream (Acanthopagrus berda) (42%) [31], zebra seabream (D. cervinus) (43.8%) [22], and sharsnout seabream (Diplodus puntazzo) (43-47%) [24,32]. Tacon and Cowey [33] reported that generally fast growing fish species require higher protein levels in their diets compared to the slow growing species.…”

“…Similar to the findings in the present study for salema porgy, Sá et al [21] and Coutinho [22] also reported other sparid candidates such as white seabream (Diplodus sargus) (0.89%/day) and zebra seabream (Diplodus cervinus) (0.8%/day) as slow growing marine species, respectively. On the other hand, higher SGRs of 1.22%/day [23] and 1.54%/day [24] were recorded for two-banded seabream (Diplodus vulgaris) and sharpsnout seabream (Diplodus puntazzo), respectively.…”

Effects of Dietary Lipid Level on Growth and Feed Utilisation of Gilthead Seabream (Sparus AurataL.) Reared at Mediterranean Summer Temperature

“…However, our results are in agreement with previous findings on the same species (Venou et al, 2006;Couto et al, 2008;Bonaldo et al, 2010) and on other species like Sunshine bass (Hutchins et al, 1998) and European seabass (Peres and Oliva-Teles, 1999). This pattern may be due to the higher content of starch in low lipid diets, which could stimulate a de novo lipid synthesis and deposition in the liver (Evans et al, 2005) or increase hepatic glycogen deposition (Wilson, 1994;Couto et al, 2008;Coutinho et al, 2012). Nevertheless, the VSI was not significantly affected by dietary lipid levels even thought a slight sloping trend was observed from D20 towards D24, most likely correlate to the HSI values.…”

Macronutrient Requirements of Silvery-Black Porgy (Sparidentex hasta): A Comparison with Other Farmed Sparid Species

“…Comparison between the optimum dietary protein/energy (P/E) ratios in the on-growing stage of different sparid species. The table includes fish body weight range tested, dietary protein and energy range tested and optimum dietary protein and P/E ratios in different sparid species [8,9,[11][12][13][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. …”
