Energy and protein requirements of growing fish can be quantified as the sum of the amounts of energy and protein retained as growth plus the amounts simultaneously lost from the body. The requirement for dietary gross ...

Traditional treatments of parasitic and bacterial diseases are based on chemotherapeutic com- pounds such as chloramine-T and CuSO4. Although many compounds are used in fish treat- ments, their undesirable effects are not ...

Experiments were performed to investigate the influence of meal frequency on growth, gonad weight and fertility in an ornamental fish, the red swordtail Xiphophorus helleri. Five groups of uniform-sized 30-day juveniles ...

Triplicate groups of subadult catfish (Clarias gariepinus; 102.18±30.48 g) were fed a purified diet to satiation twice or three times a day during the daylight hours for 26 days. Fish fed twice a day consumed 1.42±0.49% ...

The DNA of five strains of discus (Symphyodon aequifaciata) were compared by random ampli- fied polymorphic DNA (RAPD PCR) using seven primers. Only two primers (ZG4 and ZG8) were suitable. Using primer ZG8, the red turquoise ...

One-year rope-grown mussels (Mytilus galloprovincialis Lam.) with a mean length of 37.6±0.52 mm and live weight of 5.02±0.28 g were collected from fish farm mooring ropes and cultured in cotton or nylon socks in a long-line ...

Three diets including 13.2%, 22% or 30.5% carbohydrates as extruded wheat meal were fed to rainbow trout, Oncorhynchus mykiss (initial weight 34.8 g), for twelve weeks to investigate their influence on growth, protein and ...

An allelic cross between Salmo trutta fario and Salvelinus alpinus was carried out under con- trolled hatchery conditions. Survival to the eyed stage was significantly lower for the hybrid than for both purebreds. There ...

Rainbow trout, Oncorhynchus mykiss (mean weight 70.8±1.0 g SEM) raised in the Sea of Marmara (Turkey), were used for a preliminary gastric evacuation study. After being starved 72 hours, three groups of 110 fish, each, ...
