Through the the the mountain three different water pond major chemical factors (pH value, SS, of of COD Cr , ΣP, NH 3 -N In NO 2 -N, NO 3 -N, phenol, mineral oil) content and grass, silver carp, carp muscle nutrients (crude protein, crude fat, moisture, flavor amino acid), and phenol content determination to study the correlation between the the main hydration factor fish muscle composition and muscle quality, designed to identify the mountain pond major water chemistry factor their degree of impact on the quality of aquatic products, for the reasonable future to improve a mountain pond water environment, production Aquatic provide a scientific basis. The results of measurement showed that: 1. SS, the CODCr content type Ⅰ Shelters> Ⅱ Tong> Ⅲ Tong and the the type Ⅰ ponds content significantly higher than type Ⅲ Tong, type II and III type Tong, the difference was not significant. 2. ΣP, NO 2 -N content of the three types of ponds content have been exceeded, but the three categories Tong difference was not significant. 3. Phenol, NH 3 -N content I type Tong> Ⅱ type Tong> Ⅲ-type pond, and type Ⅰ Tong was significantly higher than that of Ⅱ, Ⅲ type pond type II Tong and Ⅲ Tong differences are not significant . 4. , Ⅲ type pond, mineral oil content type Ⅰ Tong> Ⅱ type Tong> Type I Tong extremely significantly higher than Ⅱ type III pond type II Tong very significantly higher than that of type Ⅲ pond. 5. The three types of pond grass, silver carp, carp muscle crude protein, crude fat content of type Ⅰ Tong> Ⅲ Tong> II-type pond, and type Ⅰ Tong Tong was significantly higher than that in type Ⅱ, Ⅲ type Tong Tong type Ⅱ significant difference. 6. Grass carp, carp muscles flavor amino acid content type Ⅲ Pond> The type Ⅱ Pond> Ⅰ pond, in addition to the grass carp alanine Ⅲ type Tong significantly higher than Ⅰ, Ⅱ type pond, the other three amino acids that glutamate days aspartic acid, glycine content of type Ⅲ the pond very significantly higher than Ⅰ type II pond type II Tong also very significantly higher than that of type Ⅰ Tong. The pond fish muscle flavor amino acid content of different fish and different, that carp silver carp> grass carp. 7. Grass carp, carp muscle phenol content I Tong> type Ⅱ Tong> Ⅲ Tong and type Ⅰ Tong extremely significantly higher than Ⅱ type III pond type II Tong very significantly higher than that of type Ⅲ pond; different fish differences carp> silver carp> grass carp. Comprehensive evaluation of the test results from water quality and fish muscle, three types of ponds are subject to varying degrees of pollution, but the the type Ⅲ pond water quality is better than I and type II pond. The type Ⅰ pond water pollution is very serious, especially carp phenol content seriously overweight.
