Intensive aquaculture is adopted by more and more fish farms in China. This paper focuses on the typical water monitoring and controlling methods in intensive fish culture in Chinese fish farms. The paper illustrates the main factors in fish culturing and the way to control them: dissolved oxygen (DO), temperature, PH, particulate matter and ammonium.

BACKGROUND Preliminary studies have identified known bacterial pathogens in the knees of patients with osteoarthritis (OA) before arthroplasty. AIMS The current study was designed to determine the incidence and types of bacteria present in the synovial fluid of native knee joints from adult patients with diagnoses of septic arthritis and OA. PATIENTS AND METHODS Patients were enrolled betwe...

An experiment was conducted in nine 200-m2 earthen ponds at the Asian Institute of Technology (AIT), Thailand from 17 July 2003 to 3 March 2004 (230 days). The objectives of the study were to assess the feasibility of co-culture of lotus and hybrid catfish in intensively fed ponds, to assess nutrient recovery from feed waste by lotus plants, to assess pond mud characteristics after lotus-fish c...

Growth hormone (GH) transgenes can significantly accelerate growth rates in fish and cause associated alterations to their physiology and behaviour. Concern exists regarding potential environmental risks of GH transgenic fish, should they enter natural ecosystems. In particular, whether they can reproduce and generate viable offspring under natural conditions is poorly understood. In previous s...

Fermented fish food products have been extensively studied in Asia's fermented food culture. We have attempted to categorize the different types of fermented fish products seen in some of the Asian countries as part of a cultural context indicator analysis. Categorization is available through two cultural context indicators: the macro cultural context indicator and micro cultural context indica...

Real-time PCR and fluorescence in situ hybridization (FISH) were evaluated as rapid methods for the diagnosis of bacterial meningitis and compared to standard diagnostic procedures. For PCR, a LightCycler approach was chosen, implementing eubacterial and specific PCR assays for the most relevant bacteria. For FISH, a similar probe set containing eubacterial and specific probes was composed of p...

The objectives of the present study were to compare growth performance and feed conversion ratios of brook trout (Salvelinus fontinalis) and Black Sea trout (Salmo trutta labrax) in monoculture and duo-culture tank reared conditions. The fish were about 9-month-old hatchery reared brook trout and Black Sea trout with initial weights of 24.18±0.64 (n=60) and 23.87±1.11 (n=60) g, respectively. Fi...

Fish that are colored in nature often acquire faded coloration under intensive culture conditions. Experiments adding top-coated algae to the diets of ornamental fish have resulted in color enhancement. Freshwater red velvet swordtails Xiphophorus helleri, rainbowfish Pseudomugil furcatus, and topaz cichlids Cichlasoma myrnae became significantly more intensely colored when fed a diet containin...

Group B streptococci (GBS) are the most frequent pathogens in neonates with sepsis. A rapid screening method is required to identify carriage of GBS in pregnant women at the time of delivery. In order to detect GBS in vaginal specimens, the efficiency of the standard culture versus fluorescent in situ hybridization (FISH) was investigated. In 258 examined vaginal specimens, FISH identified 58 o...
