{"title":"The Distribution of Oceanographic Parameter Conditions in the Swordfish (Xiphias gladius) Fishing Ground in the Southern Indian Ocean off Java","authors":"None Hasmawati, None Adam","doi":"10.9734/ajee/2023/v22i3490","DOIUrl":"https://doi.org/10.9734/ajee/2023/v22i3490","url":null,"abstract":"The Southern Indian Ocean off Java is one of the potential locations for catching swordfish. One crucial factor in improving fishermen's productivity is the availability of information regarding the characteristics of waters related to potential fishing areas. This research aimed to determine the distribution conditions of several oceanographic parameters such as sea surface temperature, salinity, chlorophyll-a, and surface currents using remote sensing data at the swordfish (Xiphias gladius) fishing ground in the Southern Indian Ocean off Java. This research was conducted from April 27, 2022, to December 12, 2022, in the Indian Ocean. Data for several oceanographic parameters were obtained from the data.marine.copernicus.eu website from April 2022 to December 2022, and the coordinates of the swordfish (Xiphias gladius) fishing ground were obtained from KM Lulu Marina 08, which operates in WPPD 57. Data from data.marine.copernicus.eu are the result of reanalysis methods developed by the Copernicus Marine Service (CMS) using multisensor satellite images data such as MODIS-AQUA, NOAA20-VIIRS, NPP-VIIRS, and Sentinel 3A-OLCI. The spatial resolution of the data was standardized to 0.001 degrees using resampling techniques with B-Spline interpolation. The highest sea surface temperature (SST) at each fishing ground was recorded in April 2022 at the fishing ground ST 1, reaching 27.52°C. The lowest SST was observed in November 2022 at fishing ground ST 6, measuring 21.70°C. The lowest salinity values at each fishing ground were recorded in June 2022 at fishing ground ST 1, measuring 34.09 psu, while the highest salinity values were found in April 2022 at fishing ground ST 6, measuring 35.38 psu. The lowest chlorophyll-a concentration values at each fishing ground were recorded in December 2022 at fishing ground ST 6, measuring 0.062 mg/m3, while the highest concentration values were found in September 2022 at fishing ground ST 6, measuring 0.357 mg/m3. The lowest catch was recorded in September 2022, with only 2 fish caught, while the highest catch was recorded in November 2022, with a total of 42 fish caught. The optimal swordfish catch rate falls within the range of SST 23.47-24.74°C, salinity 34.45-34.78 psu, and chlorophyll-a concentration in the range of 0.079-0.124 mg/m3.","PeriodicalId":173278,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135966148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study area comprises of eight villages where human population varies from 83 to 312 in uphill villages and 76 to 150 in foothill villages. The cultivated area ranges from 3.37% to 18.85% of the total village geographical area with per capita cultivated area 0.117 to 0.329 ha.. The quality of forest has been affected due to absolute dependency on resources which calls for taking appropriate step to enhance forest productivity. All villages depend on rain fed agriculture, natural stream water is used to cultivate paddy in valleys, shifting (Podu) cultivation practiced in uphill areas, mid hill orchards below the Podu area and home garden adjoining habitation. Cereals, pulses and oil seeds are grown together in Podu areas. Maize is a major cereal as staple food grown in uphill villages. The village productivity of Millets, legumes and paddy is much lower than other settled agriculture areas of the state. The home garden areas are grown with vegetables and cereals especially for domestic use. However, vegetables like Tomato, Brinjal, Bin, Sweet Potato, Chilly from foothill villages are marketed. Home garden provides variety of requirements to the tribal community round the year. The production of agriculture sub-system is not sufficient to meet the food requirement of villages and rice distributed to villagers meet this gap. However, crops grown as horticulture products (Jackfruit, Pine apple, Banana, Orange, Mango) and a few Millet crops in the uphill villages like minor Millets, are exported to markets for earning money as these are only assets recorded as high energy valued products. Odisha Millet Mission (OMM) may need to provide interventions to these villages with modern approach to increase Millet productivity including improvements in seed quality and health condition of the tribal community. To ensure sustainability of the traditional cultivation and livelihood system, involving the people of these villages in forest-based activities other than agriculture will lead to protecting the indigenous biodiversity of this region.","PeriodicalId":173278,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136155241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Households were considered as sampling units and these were selected using systematic random sampling technique. The interviews were conducted in a semi-structured manner and colored photographs of the Mountain bongo and 12 other selected mammals found in the region were used to assess respondent’s basic knowledge about the animals.&#x0D; Results: The results captured 142 informants where 71.8% of the respondents could identify the mountain bongo but only 18.3% were aware of its vernacular name. Knowledge on habitat requirements, feeding habits, threats and conservation value differed significantly from what was expected (p<0.05). Based on logistic regression, the knowledge could be predicted based on gender and age and whether one had a previous interaction with the animal. We found that 57% of the respondents supported bongo conservation whereas 40.8% were undecided and this was associated with lack of knowledge about the animal. In addition 27.5% of the respondents appreciated mountain bongo because of attracting tourists, 12.0% felt that the antelope was attractive, 8.5% liked its size, 4.2% liked its products such as bushmeat, 4.2% liked its aggressiveness and 0.7% liked its interesting behaviour.&#x0D; Conclusion: Although bongos could be identified by most respondents, basic ecological knowledge of the animal is limited in the community. A pro-conservation attitude towards bongos exists in the community, but the utilitarian value attached to it and its habitat could be a threat to its conservation in the Mt Kenya. Local community support for conservation of the Mountain bongo in Mt Kenya was influenced by gender, age and knowledge of the animal and these factors should be considered when creating conservation awareness in the community.","PeriodicalId":173278,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134913349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, an analysis of alpha diversity in the Banas River corridor of Gujarat was conducted using the quadrate sampling method. The flora of the Banas River corridor in Gujarat demonstrates moderate levels of species diversity, evenness, and richness, indicating a vibrant and diverse ecosystem. Total 133 tree and Shrub species were observed from area. The Shannon diversity index, which measures the variety of plant species present, yielded a value of 2.26. This indicates a reasonable level of species diversity within the area. The Simpson diversity index, which assesses the distribution of individuals among species, resulted in a value of 0.88, suggesting a balanced distribution and promoting a healthy ecosystem. Additionally, the evenness value of 0.92 indicates an equitable representation of species, ensuring that no single species dominates the flora and allowing for the coexistence of multiple species. The Menhinick index, which measures species richness, provided a value of 2.16, indicating a moderate level of species richness in the Banas River corridor. This suggests that the area is home to a diverse range of plant species. Overall, the data from the alpha diversity analysis highlights a diverse and stable ecosystem in the Banas River corridor, characterized by a vibrant mix of plant species. This diversity promotes ecological resilience and the coexistence of different species, contributing to the overall health and functioning of the ecosystem.","PeriodicalId":173278,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135099557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But current literature indicates that studies on the formation of participatory forest management boundaries for governance of forests are scanty. Thus this paper uses Arabuko-Sokoke Forest Reserve as a case study to examine the extent to which its forest resource and resource users’ boundaries are developed by utilizing a qualitative approach for data collection. The researchers purposively sampled 100 respondents from communities involved in participatory forest management and 90 non-participating communities in the participatory forest management arrangement. Also 30 key informants from heads of government agencies such as Kenya Forest Service, Kenya Wildlife Service, National Museum of Kenya, Non-Governmental Organizations such as Nature Kenya, Community Based Organizations and leaders from the business community working in the Arabuko-Sokoke Forest Management were utilized in the study. The analysis of qualitative data from written notes and audio recordings was coded into similar themes and used to answer the study objective. The results show that both participating and non-participating communities in the participatory forest arrangement are aware of the forest resource and resource users’ boundaries. It is concluded that boundaries are essential in governance of forest resource and users’ boundaries. It is recommended that policy makers need to clearly define boundaries for resource use and resource users’ for enhanced conservation of forest resource and improved community livelihoods.","PeriodicalId":173278,"journal":{"name":"Asian Journal of Environment & Ecology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129315503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
