| Botos (Inia geoffrensis) are currently provisioned for use in tourist attractions in five sites in the Brazilian Amazon. Despite the known negative effects associated with human-wild dolphin interactions, this activity has been regulated and licensed in the Anavilhanas National Park in Novo Airão, Amazonas State, Brazil. We present an updated evaluation of the perception of the local community concerning the possible socioeconomic impacts of this tourism in Novo Airão. In April 2011, 45 interviews were conducted with inhabitants. A small segment of Novo Airão perceives currently itself as being economically dependent on the botos feeding tourism. Despite that, the economic benefits of this controversial activity apparently are not shared among most... |

| Introduction: Among the problems found in mollusc hatcheries, the feeding of growing post larvae is of primary concern. It is therefore essential to reach algal production rationalisation through precise knowledge of the nutritional requirements of the different species of spat produced, and this for a diversity of size classes. Many authors, such as HARTMAN and EPIFANIO (1973), PRUDER and al. (1976), have attempted to establish appropriate food rations in laboratory for various post larvae mollusks according to their average weight. However, it is difficult to adapt those results to hatchery experiments, since raising conditions and yield issues are totally different. The purpose of this work is to determine nutritional rations required for different post... |

| Dans le but de promouvoir l’alimentation du Tilapia en élevage dans les fermes aquacoles tunisiennes, quatre aliments composés secs ont été élaborés à partir de matières premières conventionnelles et contenant différents taux de farine de poisson de fabrication locale (0 %, 10%, 20 % et 30 %). Ces aliments composés, de 36 % de protéines brutes et 6 % de lipides, ont été testés sur des alevins de Tilapia de poids moyen initial de 2 g. Après 45 jours d’expérimentation, les poids moyens finaux ont varié entre 21,33 g et 29,34 g selon les traitements. Les meilleurs taux de croissance et de transformation alimentaire ont été obtenus par les aliments contenant 20 % et 30 % de farine de poisson, avec des taux de croissance spécifiques (TCS) respectifs de 5,82 %... |

| The effects of artificial diets were studied with different store times, between 1 week and 6.5 months in juveniles culture shrimps in fattening phase. The artificial diets were stored at environmental temperature. The quality of raw materials and finished products were controlled during the storage time with physical, chemical, organoleptical and entomological analysis also it was evaluated the growth, protein efficiency, the food conversion factor and the survival of the shrimps. The nutriments affected during storage were the proteins, lipids and the % of free fatty acids, due fundamentally to the contamination with acarids and insects. It was found that the growth and protein efficiency of juveniles shrimps decreased with the age of the feed, without... |

| The first results in the development of a standardized methodology to estimate Mnemiopsis leidyi intake rates and their impact on fish recruitment are presented. M. leidyi capability to consume lyophilized fish eggs and level of consumption of such type of preys, Artemia nauplii and rotifera were assessed. Although M. leidyi can consume lyophilized fish eggs, intake rates were extremely low, often null and in all cases lower than those estimated for the other types of preys offered. The increase of feeding rate on each prey was proportional to ctenophores size growth. The results observed suggest that consumption of fish eggs would not affect recruitment. However, there is not a uniform methodology in the literature that allows for standardized... |

| In the frame work of a PhD thesis dealing with the use of artificial diets as an algal substitute for mollusks, the Laboratory of Aquaculture & Artemia Reference Center (State University of Ghent, Belgium) is organizing an inquiry which aims at drawing up an inventory of algal substitutes, their cost and applications, and their relative importance and cost-efficiency compared to live algae. The questionnaire has been sent to more than 200 people who are involved in the practice of culturing bivalves. The results will be treated as part of the PhD work and a free copy of the resulting report will be sent to all those who are returning the form. The questionnaire will be presented at Aquaculture Europe 1991 in Dublin under the form of a poster. The... |
