Caractérisation De La Diversité, De La Structure Des Tailles Et Du Stress Écologique Au Niveau Du Peuplement Des Poissons Sur Le Fleuve Bandama (Côte d’Ivoire, Afrique De l’Ouest)

La connaissance de la faune ichtyologique des eaux ivoiriennes préoccupe à la fois les scientifiques et les responsables de développement du secteur de la pêche. En effet, l’intensification croissante de l’exploitation des ressources halieutiques en milieu continental fait planer de réels risques de régression et de disparition des espèces.Cette étude vise à caractériser la variation spatio-temporelle de la fauneichtyologique et d’identifier les indices biologiques qui déterminent la distribution des espèces de poissons et l’état d’exploitation de ces poissons dans le fleuve Bandama.Les poissons ont été échantillonnés de juillet 2019 à juin 2020 à partir des captures des pêcheurs locaux. Chaque spécimen identifié, est pesé et mesuré.L’analyse spatio-temporelle a indiqué une variation non significative (p > 0,05) de la faune ichtyologique et des indices de diversité H’ et E. Néanmoins, L’analyse de la structure du peuplement (H’ de 2,09 à 2,34; E de 0,83 à 0,85) a révélé un milieu fluvial assez diversifié. Il est dominé par les Cichlidae et Cyprinidae au niveau des familles et Labeo coubie, Coptodon zillii et Chrysichthys nigrodigitatus au niveau des espèces quel que soit le site de pêche. Ce peuplement est composé majoritairement de spécimens juvéniles. Les résultats de ce travail constituent une étude de base pour les gouvernants dans la mise en place de plan de gestion durable des ressources halieutiques en milieu continental.L’essentiel de la production du fleuve Bandama est fourni par les Cichlidae et dans la localité de Tiassalé. Néanmoins, les indices de diversité calculés montrent une ichtyofaune diversifiée. Cette ichtyofaune est dominée par des juvéniles. Knowledge of the ichthyological fauna of Ivorian waters is of concern to both scientists and those responsible for the development of the fishing sector. In fact, the increasing intensification of the exploitation of fishery resources in the continental environment poses real risks of regression and disappearance of species.This study aims to characterize the spatio-temporal variation of the ichthyological fauna and to identify the biological indices which determine the distribution of fish species and the state of exploitation of these fish in the Bandama River.The fish were sampled from July 2019 to June 2020 from the catches of local fishermen. Each identified specimen is weighed and measured.The spatio-temporal analysis indicated a non-significant variation (p> 0.05) in the ichthyological fauna and the indices of diversity H 'and E. Nevertheless, the analysis of the structure of the stand (H' of 2.09 at 2.34; E from 0.83 to 0.85) revealed a fairly diverse fluvial environment. It is dominated by Cichlidae and Cyprinidae at family level and Labeo coubie, Coptodon zillii and Chrysichthys nigrodigitatus at species level regardless of the fishing site. This stand is mainly composed of juvenile specimens. The results of this work constitute a basic study for those in charge in the establishment of a plan for the sustainable management of fishery resources in the continental environment.Most of the production of the Bandama River is supplied by the Cichlidae and in the locality of Tiassalé. Nevertheless, the calculated diversity indices show a diversified ichthyofauna. This ichthyofauna is dominated by juveniles.

Juridical analysis of the regulation of fishery resources in the Indonesian exclusive economic zone

As an archipelagic country, Indonesia has a wealth of living and non-biological natural resources, especially in its exclusive economic zone, specifically in this zone, there are an abundant wealth of fishery resources, but the economy and welfare level of traditional Indonesian fishers are still below the poverty line, in addition to the management of exploration and exploitation of fishery resources, Indonesia faces various problems, one of which is a problem with legal provisions. Therefore, researchers will analyze legal problems in managing fishery resources in this study's exclusive Indonesian economic zone. To answer the questions in this study, the authors used normative juridical research methods, and the results of the analysis were described using qualitative methods. After reviewing the literature, the study results indicate that legal problems in the fisheries sector are due to overlapping regulations and conflicting regulations. For this reason, in this study, the authors suggest the need to revitalize the law in the fisheries sector by harmonizing the law.

Opportunities and Strategies for the Blue Economy Through the Empowerment of Sumatera Coastal Communities in Supporting the Realization of the National Food Security

A strategic step on food security was directed by president to the Ministry of Defence. Coastal communities are key actors in the realization of the blue economy and are the determinants of the successful implementation of Indonesia’s policy to becoming the Global Maritime Fulcrum. There are ten provinces on Sumatera which have marine coastal areas with abundant fishery potential. However, that potential has not been fully utilized. This article aims to review opportunities and strategies in realizing the blue economy by empowering coastal communities in the Sumatra. The method was a qualitative exploratory method with SWOT and combined with SSM analysis. The data sources were obtained through secondary data from literature studies, comparisons through multi institutions data. The study found that community empowerment can be done by considering the potential of fishery resources and the community’s interest in managing the fisheries sub-sector. The development of national food barns should be focused on the Blue Economy sector and can be started through the Sumatra region. Stakeholder synergy can be integrated in fostering, supervising and mobilizing coastal communities in supporting their welfare.

EEL (Anguilla bicolor bicolor) Rearing Techniques at the UPTD for Conservation and Supervision of Marine Fishery Resources of Sicincin, West Sumatra

Eel has a savory meaty taste and contains high levels of Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA). The purpose of this observation was to determine intensive rearing techniques for eel (Anguilla bicolor bicolor) at the UPTD KPSDKP for Conservation and Supervision of Marine Fishery Resources of Sicincin, West Sumatra. The preparations conducted for rearing the eel consist of providing seeds, pond preparation, water supply, feed management, water quality control, disease control, growth sampling, and harvesting eel for consumption size. The eel seeds were obtained from natural catches of glass eel in the Cimandiri river, Pelabuan Ratu, West Java. Preparation of the eel pond included cleaning the concrete pond, filling the water by observing the water input into the eel pond. The provision of water for eel rearing was obtained directly from the Kapalo Ilalang Sicincin irrigation channel to the holding tanks before flowing to the eel rearing pond. Feeding management was carried out 2 times a day, namely the percentages of feeding in the morning (35 %) and at night (55%) with a feeding rate of 3%-5%. The feed provided to these eels was in the form of a paste made of powdery pellets. Measurements of water quality for eel rearing during observations were temperature (27-29°C), pH (6-7), DO (5.9-7.8 ppm), salinity (3-4 ppt) and NH3 (0.02-0.07 mg/l). In our observations, parasites shaped like cotton were discovered, which attacked the eel body, causing death. In growth sampling, the measurement of the length and body weight of the eel once a month is necessary to be done.
