It plays a very important role in fishing activities because it determines whether fishermen go fishing. In the North-Eastern part of Madagascar, the strong trade wind locally called “Varatraza” which blows from the East to the West was observed from the month of May until the end of October. This period corresponds to the decrease in fishing products in this north-eastern part of Madagascar and including the Rural municipality of Ampisikinana. In addition, the west wind called the Monsoon locally called “Talio” which brings rain accompanied by storms extends from the beginning of November to April. In the rainy season, the majority of winds in this region do not exceed 25 km/h, except during cyclones (SAVA region monograph) which determines the abundance of fishing products. 2.5 Hydrography The Loky-Manambato MPA entire region benefits from a dense hydrographic network (monograph of the SAVA region) of which several rivers bring nutrient salts to all fishing areas. The noted most important rivers are that of Manambato in the South; the Andravina and Manankolana rivers in the center and the Loky river in the north. These four rivers provide the renewal of nutrient salts almost throughout the year, especially the two rivers at the southern and northern ends of the MPA. The existence of these rivers is an important indicator for the management of fisheries resources. Because these rivers not only play the role in the renewal of nutrient salts but also they hold the irreplaceable and unique ecosystem sheltering incredible biodiversity and are among the most productive ecosystems in the world (FAO, 2009) thanks to their mouth provided with mangrove ecosystem. Knowing the environmental parameters of the understudy zones, the research methodology considered for the present work is discussed in the next section. 3 Investigation on Research Methodology and Used Materials The methodology adopted and deployed in order to obtain the data and information necessary to resolve the problem of our research subject is investigated in this section. To have information and knowledge on the theme of the study and the study area, it was necessary to carry out bibliographic readings. These must be done before, during and after field work. The bibliography before the field trip above all makes it possible to properly prepare data collection strategies in order to obtain reliable results. These bibliographic searches are carried out not only on the internet but also in the University of Antsiranana libraries. 3.1 Decision making and information sharing One reminds that the rural municipality under study belongs to the district of Vohemar (SAVA region monograph). It recorded a total of 4,000 inhabitants according to the monograph of the SAVA region in 2003. The population of the rural municipality and including Fokontany Antsampilay is made up of various ethnic groups but the Sakalava ethnic group largely dominates with more than 80%. It should also be noted that Fokontany is marked by a high proportion of “non-natives”. This requires the establishment of a fisheries management policy as well as fisheries resources in order to increase fishing products while reducing overexploitation. The Antsampilay fokontany, even if it is part of the rural municipality, the information system keepspace with the advancement of modern technology. In addition to the meeting of the village community, the information and fishing regulations adopted can be communicated by telephone “Orange and Telma operators”. The aim of sharing information in the context of resource management is to improve transparency on the management method and the structure that we will adopt in the fishing sector. The success of fishing activities depends on the used physical materials as specified in the next subsection. 3.2 List of physical materials During field trips, numerous fishing products were captured and exploited. They belong to the groups of pisces, shellfish and cephalopods. These types of fishing technique are practiced mainly by men who have been able to dive with equipment (Figure 10) such as fins, mask and tubas. To carry out this work, certain materials are necessary described as follows: A camera equipped with a GPS to take the geographic coordinates of these study sites as well as photos of the
