DETECTOR ELEMENTS (SEO) TO IDENTIFY FOOD NEEDS IN THE EARLY STAGES OF ORNAMENTAL FISH LARVAE: REVIEW OF METHODS AND PRINCIPLES APPLIED

Knowledge of nutritional requirements ornamental fish larvae is limited and mostly qualitative information obtained to very little information is more accessible. Assessment of food requirements reasons like small size and sensitivity ornamental fish feeding in the early stages of life can be stopped. The fact that most species of fish larvae stage using the following nutrients (microdietes) will not grow as well as problems such as determining the exact ratio of taking food and diet digestibility of accountability is very important and necessary. Today detector elements in order to study better understanding of nutritional needs of the decade to 60 deaths intensity are used. Studies also limit the detector elements and results should be interpreted with some limitations to be done in terms. This is a review article on the methodology used tracer elements in feeding studies, including marine ornamental fish larvae: their advantages and limitations, and describe them with examples of related studies, such as getting food, digestion, absorption and utilization of nutrients is. Some of the methods applied tracer elements in feeding larval stage was run in this information is available. These studies may improve physiology Pain feeding larvae of marine ornamental fish and their food requirements. Feeding method, a feeding tube labeled and radiation is significant (usually carbon 14 is marked), based on the browser to identify the stool is available to be followed, in the tissues is maintained and is dissimilation. After a few hours to determine the capacity of digestion/absorption of amino acids (AAs) different fatty acids (FA) and categories as well as fat ratios energy supplement is used. A basic combination of live food that proteins with a stable isotope is marked and a technique spectroscopic/spectrometric the enriched isotopes in the individual amino acids can determine, is that using this method can be essential amino acid to the diet to the ideal estimation. How food can be measured both techniques using micro nutrients live food marked with radiation or stable isotopes to assess the factors such as how to get food, get food of nutritional requirements and digestive physiology is improved. However, the results of tracer elements necessarily representative of Gastroenterology and metabolic efficiency in larval feeding or breeding system are not Open Ocean. When the method in the standard conditions are used, can be determined as a tool for comparison between changes in attendance and antigenic study be used. However, the effects of long-term verification tests and nutritional needs of early larval growth are advisable.
