  30. <meta content="This study determined the effect on growth efficiency, nutrient retention and apparent digestibility
  31. of varying dietary protein concentration and protein/energy ratio for juvenile southern rock lobster,
  32. Jasus edwardsii. Isoenergetic diets were formulated at six crude protein levels (5% increments
  33. between 24% and 50%) and at each of two lipid levels (5% and 9%). Duplicate groups of 10 lobsters
  34. (initial weight mean 3.58 SE 0.86 g) were held in 50-l tanks, in a recirculating seawater system at 18 degrees Celsius and fed to 95% satiation over a 12-week growth trial. There were significant ( P < 0.05) differences in
  35. apparent crude protein digestibility (76.4-83.2%), but no difference in dry matter (mean 59.1 SE 0.8%) or
  36. energy digestibility (mean 77.7 SE 0.8%). Survival, feed intake, digestive gland index, protein efficiency
  37. ratio, energy efficiency ratio and whole-body composition were not significantly affected by dietary
  38. treatment. The relationship between nutrient intake and weight gain indicated optimal dietary
  39. digestible crude protein (DCP) levels of 29% and 31% when lobsters were fed diets containing 5%
  40. and 9% lipid, respectively. For the two lipid levels studied, the optimal dietary protein/energy
  41. requirement was similar for maximum weight gain (29 gDCP/ MJ DE) and feed conversion ratio

  296. of varying dietary protein concentration and protein/energy ratio for juvenile southern rock lobster,&#13;
  297. Jasus edwardsii. Isoenergetic diets were formulated at six crude protein levels (5% increments&#13;
  298. between 24% and 50%) and at each of two lipid levels (5% and 9%). Duplicate groups of 10 lobsters&#13;
  299. (initial weight mean 3.58 SE 0.86 g) were held in 50-l tanks, in a recirculating seawater system at 18 degrees Celsius and fed to 95% satiation over a 12-week growth trial. There were significant ( P &lt; 0.05) differences in&#13;
  300. apparent crude protein digestibility (76.4-83.2%), but no difference in dry matter (mean 59.1 SE 0.8%) or&#13;
  301. energy digestibility (mean 77.7 SE 0.8%). Survival, feed intake, digestive gland index, protein efficiency&#13;
  302. ratio, energy efficiency ratio and whole-body composition were not significantly affected by dietary&#13;
  303. treatment. The relationship between nutrient intake and weight gain indicated optimal dietary&#13;
  304. digestible crude protein (DCP) levels of 29% and 31% when lobsters were fed diets containing 5%&#13;
  305. and 9% lipid, respectively. For the two lipid levels studied, the optimal dietary protein/energy&#13;
  306. requirement was similar for maximum weight gain (29 gDCP/ MJ DE) and feed conversion ratio&#13;
  307. (FCR, 30 gDCP/MJ DE).</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">http://www.elsevier.com/locate/aqua-online&#13;
