The samples were collected at 60 min intervals over a period of 12 h per day during two wks. Livest Res Rural Dev. The improper disposal of mercury-containing substances may cachaa toxicity and accumulate in fish tissues. To enhance the nutritional value of plant materials for fish, simple methods for processing suitable for marginal areas have been investigated.

Animals and Feeding Trial A total of juveniles of Piaractus brachypomus with a similar initial body weight of All the energy values of the tested ingredients were relatively low and aquatic macrophytes can be described as a feed source poor in lipids and soluble carbohydrates, which do not possess desirable features to be used as an energy source.

Fish, Acute Toxicity Test. Este valor es cercano a lo registrado en otras especies de peces y representa el primer registro de toxicidad aguda para el mercurio en cachama blanca. Particularly, diet and dietary compound digestibility are essential for exact determination of nutrient demands in fish metabolism.
