This article reviews the current state-of-theart for algae use in aquaculture, plus recent developments in algal biomass as a microor bulk ingredient in formulated animal feeds (terrestrial livestock and aquaculture species). Microalgae provide an important direct or indirect feed source for early developmental stages of many farmed finfish, shellfish and invertebrate species. Hatcheries typica...

radiographic evaluation of the third molar tooth to determine its position and degree of development is an important part in diagnosis and treatment planning, as well as in forensic dentistry procedures. the objective was to investigate the developmental stages of third molars in relation to chronologic age, gender and location (maxillary/mandibular) in an iranian population.the data were colle...

The development of the nervous system is a rather complex process known to be affected by different drugs and chemicals. Therefore, regulatory test guidelines have been adopted for the prediction and assessment of developmental neurotoxicity (U.S.EPA OPPTS 870.6300 and OECD TG 426). However, current in vivo test methods are laborious, costly and necessitate use of considerably high numbers of l...

Fish oocyte development monitoring is a mandatory operation when studying breeding in captivity as well the wild. In aquaculture, it required to determine best fertilization time. wild, helps detect spawning grounds, distribution of fish species and interaction between animals their environment. both settings, conventional technique for developmental stage identification consists handling sampl...
