Sediments from a new farming ponds (A) and an old one (B) were sampled and used to carry out indoor experiments for researching on nitrogenous compounds diffusion at the water-sediment interface of farming ponds.

From 2004 to 2005, the pond culture experiment of Tinca tincal.

The composition,the proportion of edible part,and the amino acid content,the fatty acid content and mineral content in the edible part of crab(Eriocheir sinensis) were analyzed and compared between pond cultured type and wild type found in the Yangtze river.

Pond culture of grass carp fingerling was studied after adding 0.

To solve the pond eutrophication, the bacillus had been isolated from the aquaculture ponds and determined its ability of phosphorus decomposition.

This study was carried in Dongli District and Xiqing District aquaculture ponds in Tianjin,and the experiment included controls,zeolites,urease inhibitors,bacillus and their combination treatments.

The concentration levels and their changes of 17 aquatic eco-factors including chlorophyll-a, water temperature, pH, DO, COD, NH_4~+-N, PO_4~(3-)-P, NO_3~--N, NO_2~--N, NH_3-N, CO_2, turbidity, alkalinity, hardness, Ca~(2+), Mg~(2+) and total bacterial count were analyzed in totally 62 detecting times in 16 Siniperca chuatsi culture ponds in Xinhui and Nanhai cities of Guangdong Province.

By investigating of 12 culture ponds of Litopenaeus vannamei in Beihai, Guangxi, species composition and densities of microalgae have been studied.
