Abstract. Patawari AMY, Anna Z, Hindayani P, Dhahiyat Y, Hasan Z, Putri IAP. 2022. Sustainability status of small-scale fisheries resources in Jakarta Bay, Indonesia after reclamation. Biodiversitas 23: 1715-1725. Reclamation in Jakarta Bay was initially implemented by constructing a giant 60 km long embankment in the area and 17 small islands in front of the coast of North Jakarta, but then it was stopped in 2018. After reclamation closures have affected fishery resources, especially small-scale ones that rely on catchment areas around the coastal waters of Jakarta Bay. To ensure the resource utilization level that meets the needs of the present and future generations, managing sustainably small-scale fish resources is crucial. This study aimed to analyze the sustainability status of small-scale fisheries in Jakarta Bay after reclamation. The results showed that efforts to manage small-scale fishery resources in the waters of Jakarta Bay-from the dimensions of fisheries, ecological, social, legal and institutional- are in unsustainable conditions. To improve the status, policy makers should consider 16 prioritized attributes on ecology, resource potential, economic, social, legal and institutional.

Abstract. Paujiah E, Dhahiyat Y, Herawati T, Iskandar, Haryono, Zulfahmi I, Fahri. 2023. Length-weight relationships and condition factors of brackish water catfish, Mystus gulio (Hamilton, 1822) from three different estuaries, West Java, Indonesia. Biodiversitas 24: 2855-2864. This study investigated the biometric condition of brackish water catfish (Mystus gulio Hamilton 1822) collected from three different estuaries in Cianjur District, West Java Province, Indonesia. Data (class interval, growth pattern, and factor condition) were sorted based on time, location, and season. Water quality parameters measured include temperature, conductivity, TDS, hardness, resistivity, pH, DO, total oxygen, ORP, and salinity. The correlation between K-Value and water quality parameters was analyzed using multivariate analysis. Our results showed that the worth pattern of M. gulio was allometric, with condition factors value ranging from 0.904-1.042. There were variations in the growth patterns according to time, location, and fish sex. The lowest condition factor values were found in August for males and April for females. Meanwhile, the highest condition factor values were found for males on 4 June 2022 and 5 February 2022 for females. The NMDS analysis places the water resistivity and conductivity on a different axis from other environmental factors. The results of our study suggest that the estuaries in Cianjur District were adequate for supporting the survival and growth of M. gulio by providing food and suitable habitat.

Abstract. Vatani L, Hosseini SM, Akbarinia M, Shamsi S. 2017. Natural woody species biodiversity after Cypress (Cupressus sempervirens var. horizontalis) reforestation in Hyrcanian Forest,. The present study was conducted to investigate the impact of Cypress (Cupressus sempervirens var. horizontalis) reforestation (15 years old ) on woody species diversity comparison natural Hyrcanian forests. 9 sample plots with 20 × 20m area were taken in each stand by a random systemic statistical method and also control area, then natural regeneration number of woody species were measured. Shannon-Wiener for diversity index, Mechanic for richness index and Simpson for evenness index were calculated to evaluate species biodiversity, using Ecological Methodology and SPSS software. The results showed that sixteen tree and shrub species were appeared in Cypress understory naturally, that some of the species were rare. There was no significant difference between the diversity and richness index obtained for Cypress reforestation and natural forest. Regarding the rate of evenness, only in one area was found a significant difference was observed between Cypress reforestation and natural forest that in reforestation was more than natural forest (p<0.05). Regarding the results obtained on the study, Cypress reforestation did not reduce the woody plant biodiversity until the age of fifteen years old and findings of this investigation suggested that the conditions under the Cypress canopy might be suitable for the presence of some woody species, 15 years after reforestation.
