Consistent Approach

AbstractThe Ghana/Côte d'Ivoire case is the first time that an ITLOS ad hoc chamber has addressed the lawfulness of unilateral hydrocarbon activities in a disputed maritime area. This paper analyzes the Chamber's ruling on Côte d'Ivoire's submission no. 2, which covers several important issues: the jurisdiction of the Chamber to decide on submission no. 2, the alleged violation of sovereign rights, and the alleged violation of Article 83(3) of UNCLOS. The paper argues that the Chamber's jurisdictional basis of forum prorogatum is questionable, and that there are inconsistent approaches between the Judgment and the Order of the provisional measures. Additionally, there are not only inconsistent understandings of the “Ivorian maritime area” within the same submission no. 2 by the Chamber, but also a logical gap in the Chamber's reasoning with regard to submission no. 2(iii). Consequently, the Chamber's inconsistent approaches may jeopardize the persuasiveness of its judgment.

The length–length and length–weight relationships and condition factor for Macrobrachium vollenhovenii are described using samples collected from the rivers of Côte d’Ivoire. The maximum carapace lengths (CLs) registered for males and females were 63.00 and 53.60 mm, respectively. All relationships between body length and CL and weight and CL were found to be highly significant, with r2 > 0.76 (P < 0.001). In the length–length relation, the allometry coefficient (b) ranged from 0.75 to 1.46 and varied according to the considered length and groups. The value of b of the length–weight relationship varied from 2.55 to 3.30. Although the three allometry types were observed, overall, M. vollenhovenii exhibited negative allometry. The condition factor (K) did not significantly vary among males and females. The K value decreased from the eastern to western Côte d’Ivoire. The present study presents, for the first time, results on the allometric growth and condition factors of M. vollenhovenii from the rivers of Côte d’Ivoire. Further, a biological database is established for use by fishery managers and in further research on the ecology, reproductive biology and aquaculture potentialities of this species.

The Nile tilapia, Oreochromis niloticus is a fast growing fish and has a great importance for fisheries, aquaculture, and screen aquarium in Côte d’Ivoire. Parasitic infections constitute significant economic loss in fish production. The work based on Epidemiology of gill Monogenean parasites of O. niloticus from the Agneby River between August to December 2020, for the first time, was aimed to characterize the physicochemical parameters of this River, to inventory the gill Monogenean species in Nile tilapia, to analyze the parasitism as a function study areas and to highlight the parasite species’ distribution on the gill. A total of 102 specimens of fishes was sampled and examined for parasites. Gill helminthofauna of this fish consisted of Cichlidogyrus cirratus, C. tilapiae, C. halli and Scutogyrus longicornis. Fishes of the Agneby River at Agboville are more infested than the other ones due to environmental conditions. The examination of the two sides of the fish revealed that parasites species have the same affinity for the both sides of the fish. In contrast, at the level of the gill arch, these parasites preferred median gill arches (arches II and III).

Food resources of the straw-colored fruit bats Eidolon helvum (Kerr, 1792), a near-threaned species in Abidjan-Plateau were studied from August 2007 to July 2008. Faeces collection under sleeping trees and direct observations were made in order to access qualitative composition and temporal distribution of food resources of Eidolon helvum. Results show that 16 species of plants grouped into eight families and classified in three categories of plant organs were exploited by these bats. Among them, three species of plants appeared for the first time in the diet of the frugivorous bats in Côte d’Ivoire. Fruit food resources were most abundant (83%) and fruits of Ficus genus were dominant (45%). The distribution of food resources varied with the season.

Two Sides

This study was conducted in two sides of Bingerville (Abatta and Anna) in southern Côte d'Ivoire. The objective was to inventory the entomofauna of poultry farms in order to verify the presence of Alphitobius diaperinus (Coleoptera: Tenebionidae) in Côte d'Ivoire. It also aimed to establish correlation between Alphitobius diaperinus density in livestock buildings and the loss on poultry production. Thirty (30) poultry buildings were investigated during 3 months. A survey questionnaire on farm characteristics, diseases and mortality was submitted to farmers. The poultry litter was collected, transported to the laboratory and excavated. Insects were determined and counted. A total of 19661 insects were collected on both sites. Alphitobius diaperinus accounts for 96.63% of collected insects. The statistical comparison showed that A. diaperinus is the most representative insect (P <0.0001). This insect is unevenly distributed in chicken farms (n = 89, F = 3.67, and P ˂ 0.00001). Out of 18998 Alphitobius diaperinus collected, a total of 14362 (75.60%) were recorded in the column of feeders and waterers, and only, 4636 (24.40%) off feeders and waterers’. The study also revealed a strong correlation (R = +0.88) between the density of A diaperinus and the loss on chicken production due to avian diseases such as Gumboro, Newcastle, and Mareck. This insect is suspected to be the vector of these aggressive diseases of poultry. Our results reveal for the first time, the effective presence of Alphitobius diaperinus in poultry farms in Côte d'Ivoire.

The Future

Abstract The maritime boundary delimitation decision in the Ghana/Côte d’Ivoire Case is remarkable as the first decision of an ad hoc chamber of the International Tribunal for the Law of the Sea (ITLOS). This article evaluates the advantages of this critically under-examined dispute settlement mechanism, its operation in this case and the consequent prospects for the future use of such chambers. To date, the ad hoc chambers of both ITLOS and the International Court of Justice (ICJ) have rarely been used. Examining their respective procedures, legal frameworks, and performance, this article evaluates the comparative advantages and disadvantages of ITLOS ad hoc chambers vis-à-vis both ad hoc arbitration and the full bench of ITLOS. Although limited conclusions on the prospects for the mechanism’s future use can be drawn from this single decision, in light of the broadly positive outcome, prospective parties may be drawn to the possibilities and potential advantages of the ITLOS ad hoc chamber mechanism in the future.

Zanthoxylum mezoneurispinosum Ake Assi and Zanthoxylum psammophilum Ake Assi are species endemic to Côte d’Ivoire. In this study, we determined, for the first time, the composition and biological activities of essential oils obtained from each of these plants. Essential oils were obtained by hydrodistillation from different organs of each plant with a Clevenger-type apparatus and analyzed by gas chromatography–mass spectrometry (GC-MS). Thirty-four components, accounting for more than 99.9% of the overall composition, were identified in the oils. The Z. psammophilum leaf and trunk bark oils exhibited two unusual methylketones, undecan-2-one and tridecan-2-one, whereas the root oil was rich in thymol and sesquiterpenoids. The Z. mezoneurispinosum leaf and trunk bark oils were rich in monoterpenoids, whereas sesquiterpenoids were predominant in the root oil. These samples produced, for the first time, some new chemical profiles of essential oils. The oils’ antioxidant activities were determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity and ferric reducing antioxidant power (FRAP) assays. The results showed that the essential oil isolated from roots of Z. mezoneurispinosum had the highest antioxidant activity, which is in accordance with the high thymol content of that oil. We also determined the lipoxygenase inhibitory activities of the essential oils. The results showed that all of the tested oils displayed high and close lipoxygenase inhibitory activities.
