EFFECT OF RATION, TEMPERATURE AND BODY WEIGHT ON GROWTH OF BLACK PORGY,sparus MACROCEPHALUS (B.)

Chinese Journal of Oceanology and Limnology 1997年第4期15卷 289-295页

作者：李军徐世宏徐长安

Growth of black porgy. sparus macrocephalus was studied experimentally at four ration lerels from starvation to sltiation and tour temperatures ranging from 14.8 to 26.8℃ .At maximum rations. the specific growth rate (SGR) increased with temperature and was a negative linear function of body weight. The relationship betaren SGR and ration levels was a decelerating curve. Stepwise mpgression was used to derelop the predictive models for the specific growth rates. Maintenance rations and optimum ratlons both increased with increased temperature. The relationship between maintenance. optimum rations and body welght wds influenced by temperuture. Conversion efficiencies increased with ration from zero at maintenance ration to a peak at the optimum ration, then declined with further inceased ration.

The residual concentrations of HCHs, TC, DDTs, THCs and PCBs were measured in sparus auratus collected from the eastern and western sectors of the Egyptian Mediterranean Sea, as the most common fish species in the area. Gas chromatograph equipped with 63Ni-electron capture detector and 35% phenyl polysilphenylenesiloxane capillary column was used for the analysis and quantification after well-established extraction techniques. The concentrations (wet weight) of PCBs, DDTs, TCs, HCHs were: (1.87 - 616.66 ng·g-1), (0.42 - 98.28 ng·g-1), (0.06 - 2.94 ng·g-1), (0.35 - 11.77 ng·g-1), respectively in sparus auratus collected from the eastern sector. However, these concentrations as wet weight in sparus auratus from the western sector were: (5.75 - 605.53 ng·g-1), (1.53 - 226.47 ng·g-1), (0.09 - 8.12 ng·g-1), (0.26 - 5.80 ng·g-1), respectively. In general, concentrations of pesticides and PCBs in sparus auratus either from the western or eastern Egyptian Mediterranean coast were far below the international permissible levels.
