Abstract

The knowledge of fish reproduction is the most important in freshwater management continously. The research was done from February-July 2013, was aiming to describe information on reproductive aspects of belida fishes (Notopterus notopterus),i.e. sex ratio, gonado somatic stages, gonado somatic index, first size of maturity, fecundity, and spawning type. The fish Samples was taken by gill net which had many sizes such as 2, 2.5, 3, and 4 cm. Each gill net has length 30 m and width 2 m. Belida fishes have caught during research amounted 497 ind, which consisted of: 237 male and 260 female. Sex ratio male and female fish were relatively balance. The maturity gonad of male fish is faster than female fish. Featherback do spawn every month for each observation during the research. The spawning type of Featherback is partial pattern (step by step). The first size of maturity gonad from male fish was in length 135 mm and female fish was in length 162 mm. Fecundity of Featherback was in range 1.051-6.057 eggs. Fecundity is not influenced by length or weight body. For the sake to keep Featherback population needed a regulation, such as: the mesh size regulation of gillnet have to 30 mm or equal with 1.5 inci.

Abstract

Penyerang river is one of rivers which located in district of Puding Besar, Bangka regency. The mining and agricultural activities were increased at the district that lead to the decreasing of the quality of the environment, especially  for the biodiversity of fish. The aim of this research was to investigate the diversity of fish, similarity index, and domination index of fish in Penyerang rivers, district of Puding Besar, Bangka Regency. The method used was survey-sampling method by placing six observation stationsin way of purposive sampling. It was divided on certain stations, such as up, middle and down stream station, whereas two for each stations.The data collected was chemical and physicalwater parameters and fish sampleby using gillnet, scoopnet and frock. The result shows that 18 fish species in Penyerang Rivers in District of PudingBesar , Bangka Regency composed of 13 genus and 9 families were found. The diversity of fish population and species in Penyerang River indicating on average range and was not dominate by certain species. Taken together, the populations of fish in Penyerang River were uniform.

Abstract

Desa Tanah Bawah merupakan salah satu Desa yang terdapat di Kecamatan Puding Besar, Kabupaten Kab.Bangka., Kepulauan Bangka Belitung. Desa Tanah Bawah memiliki potensi besar di ekosistem pesisir seperti ekosistem mangrove yang terdapat di muara sungai upang, Ekosistem-ekosistem pesisir ini, menujang kehidupan masyarakat Desa Tanah Bawah dimana sekitar 30% masyarakat hidup bergantung ke ekosistem tersebut yang berprofesi sebagai penangkap ikan di sepanjang sungai upang. Saat ini masyarakat juga belum mengerti dan mengetahui adanya aturan Perpres No 73 Tahun 2012, yang melarang melakukan penebangan di area hutan mangrove sekaligus mengatur mengenai pelaksanaan dan pengelolaan ekosistem mangrove secara berkelanjutan. Karena keberadaan ekosistem mangrove merupakan habitat tempat tinggal berbagai macam sumberdaya yang bernilai ekonomis. Selain itu sudah terdapat aturan mengenai sanksi yang akan dikenakan ketika masyarakat terbukti tertangkap sedang melakukan kegiatan penebangan mangrove. Sungai upang yang mengalir di daerah Desa Tanah Bawah menyimpan potensi jenis ikan yang sangat tinggi baik itu yang dapat digunakan untuk ikan konsumsi maupun untuk ikan hias. Masyarakat Desa Tanah Bawah mayoritas belum begitu mengetahui ikan apa saja yang dapat dimanfaatkan untuk meningkatkan perekonomian warga. Sungai upang menyimpan potensi jenis ikan sebanyak 14 spesies, terdiri dari ikan konsumsi 7 spesies, hias 3 spesies dan konsumsi-hias 4 spesies

Abstract

Characteristics of Bangka Island which is an archipelago region with high economic potential of marine and fishery resources, it is deemed necessary to conduct research on the diversity of freshwater fish to support the increase of economic, ecological and conservation value of freshwater fish resources. Because of considering the research especially freshwater biodiversity of fish is seldom doing in Bangka Island, this research need to done. The aim of this research is to compile and identify the diversity of freshwater fish species in Bangka Island and to identify the potential utilization of freshwater fish species in Bangka Island based on the characteristics of dichromaticism and dimorphism. There are 63 species of 24 families of freshwater fish in the waters of Bangka Island. 2 unidentified fish species. Family Cyprinidae is the most caught type of 18 individuals. Fish potential analysis shows that there are 26 species of fish with potential for consumption, 33 species of fish have ornamental potential, 5 types of fish have ornamental potential and consumption, and 1 species of unidentified fish potential. Analysis of water quality in three observation streams indicates that water quality is still good for fish life

Abstract

Tempuring fish (Puntius gemellus) is a freshwater fish that belongs to the family cyprinidae, genus puntius. Ecobiological information on Tempuring fish at Bangka Island has not been found yet. The Information about Tempuring fish is limited to the study of abundance and diversity of fish species. This research aims to determine growth patterns of Tempuring fish, based on weigth and length relationship aspects. This research used a survey method, and purposive sampling.This research was carried out on the Lubuk Bakong Tua Tunu River in Pangkalpinang City Bangka Island. The results showed that growth pattern of Puntius gemellus is a negative allometric fish (b = 2.25) with a growth model W = 0.056L2.25. The parameters of aquatic environment indicate that the water quality of the measured parameters is still at an adequate threshold for the development of freshwater fish.
