Argyrosomus regius (3.0 ± 0.9 g) were exposed to different concentrations of ammonia in a series ... more Argyrosomus regius (3.0 ± 0.9 g) were exposed to different concentrations of ammonia in a series of acute toxicity tests by the static renewal method at three temperature levels (18, 22 and 26°C) at a pH of 8.2. Low temperature clearly increased the tolerance of the fish to total ammonia nitrogen (TAN) and unionized ammonia (NH3) (P < 0.05). While the 96-h LC50 values of TAN were 19.79, 10.39 and 5.06 mg L−1, the 96-h LC50 of NH3 were 1.00, 0.70 and 0.44 mg L−1 at 18, 22 and 26°C respectively. The safe levels of NH3 for A. regius was estimated to be 0.10, 0.07 and 0.04 mg L−1 at 18, 22 and 26°C respectively (P < 0.05). This study clearly indicates that A. regius is more sensitive to ammonia than other marine fish species cultured on the Mediterranean and Eastern Atlantic coasts.

In Pond A, the pre-seasonally produced post-larvae (PL) grew linearly from 0.2 g to 22.6 g in 140 days (Y = 0.19 X- 2.69; R2 = 0.97) with DGR (daily growth rate) of 0.06 g day-1. In Pond B, the over-wintered juveniles grew from 3.8 g to 30.5 g with DGR of 0.41 g during the first 30 days (weight gain of 14.42 g) and 0.13 g between 30 and 140 days (weight gain of 14.32 g). Regression equation for growth was calculated to be Y = 9.62 Log (X) + 4.51 (R2 = 0.99). Compensatory growth due to starvation or over-winter fasting has, for the first time, been demonstrated in this penaeid shrimp species in the present study. Food deprivation during the winter months resulted in growth compensation after refeeding under appropriate culture conditions. During the compensatory grow...

In experiment 1, food intake (FI) of Marsupenaeus japonicus PLs (0.96 g), injected with NPY at 0.6 microg per g BW, was investigated within 48 h posttreatment. In experiment 2, oral administration of NPY (at doses of 0, 0.125, 0.25, 0.5 microg g(-1) food) on feed intake and growth performance of Penaeus semisulcatus PLs (0.27 g) was examined for 6 weeks. In experiment 1, NPY injection significantly increased average daily FI of M. japonicus PLs within the first 24 h compared to the control (P<0.05), but its stimulatory effect decreased on the second day (P>0.05). The increase in FI was 33% during the first 24 h and 17% during the next 24 h. In experiment 2, significant (P<0.05) differences were found among the groups in terms of weight gain and food utilization (P<0.05). Mean FI significantly increased (as much as 1.3-fold...
