Abstract

Fishes used seagrass ecosystem as nursery, spawning, feeding ground, daily ruaya and food for hebivorous fish. This research aims to describe the daily variability of fish communities in seagrass ecosystems, analyze seagrass communities and analyze seagrass associations with seagrass fish. The research was conducted in March 2017 in the waters of Ketawai Island, Central Bangka Regency. Line transect methode was used for seagrass data retrieval and swept area method for fish data capture.It was found that total number of individual fish as much as 244 ind/6.000m², consisting of 17 species during the day and 13 species at night. The highest abundance of daytime fish species Gerres filamentosus 68ind / 6.000m² and Hypoatherina barnesi 81ind/6.000m² at night. Diversity index is 1,917 at daytime and 1,074 at night. The uniformity indes is 0,677 at daytime and 0,419 at night. The dominance index is 0,258 at daytime and 0,583 at night. Spesies density, species frequency, species closure, Important Value Index of seagrass were dominated by three species of seagrass is Cymodocea rotundata, Thalassia hemprichii and Enhalus acoroides. Correspondence Analysis between the density of seagrass and the abundance of fish in the afternoon forming 2 groups and at night forming 3 groups of seagrass and fish associations. The Atherinidae fish family prefers the Thalassia hemprichii seagrass species.

Abstract

One of the causes of disease in fish is declining immunity or immunity. Giving an immunostimulatory treatments deemed effective enough to reduce some of the infections that occur in addition to the use of drugs. Studies related to the use of immunostimulants in fish immune enhancement has a lot to do, both in the form of synthetic chemicals, microorganisms intact and component derivatives, as well as natural immunostimulatory ingredients derived from animal and plant groups and derivatives. Short communication study aims to elaborate immunostimulant, especially the potential of herbal plants that have been implemented so far to improve the immunity of fish infected by Aeromonas sp in freshwater fish commodities

Abstract

There are many problematic issues challenging the success of fish farming. In particular, the very intensive, monocultural nature of fish farming raises some fundamental questions about the sustainability of this type of farming. Using genetically modified organisms (GMO) for fish cultivation is one of those to help the farmer to increase the production. By focusing on "technological and management improvements" to maximize economic growth, genetically engineered (GE) food pushes the ecological and social systems to accept the logic, time scale, and control of global capitalist markets and their corporate captains. But all over the globe, industrial-style fish farming with GMO or GE development is threatening native fish and their habitats. There are also significant concerns relating to farmed fishes (including eggs) escaping into the natural environment competing with wild fish species for food and also possibly endangering wild other (fish) populations and genetic variation. But if transgenic fish are adequately contained, they will pose little risk to native population. Prevent the escape of transgenic fish and sterilization is also developed to decrease the risk. Nowadays, we just need a perspective that recognizes that the health value of fish for humans depends on the health system in which they are raised. The sustainable wild fishing practices and the establishment of organic standards for aquaculture could provide healthy fish far into the future

Abstract

Floating Net Cage (FNC) system were applied to mariculture of groupers (Family Serranidae) in marine waters of Pongok Island, Regency of South Bangka. The economic carrying capacity of the system have been evaluated based on R/C, NPV, PP, and IRR analysis. The result revealed that FNC system still gives a big opportunity as an alternative income for the local residents since it provides a multiplier effect to 127 households in the basic of symbiotic mutualism. Area suitability for grouper mariculture in Regency of South Bangka estimated only used about 0,5% of waters which provides the economic advantage for 127 households, or about 4,3% of 2.959 fishermen in the District of Lepar Pongok. Economic carrying capacity proved to be positively correlated with social carrying capacity to move the economy in the small island with reef fishery resources like Pongok Island. The government policies needed in order to support the FNC system as an economic prime mover in the coastal area or small island with potential reef fishery like in Pongok Island

Abstract

Lead (Pb) is non-essential heavy metal that is toxic to cultured fishes. Culture media containing Pb lead to health impacts on cultured fishes or even death. Compost is a material that can be used to adsorb Pb due to its humic acid and fulvic acid content. Compost with a C I N ratio of different raw materials will lead to different content of substances. This study aims to compare the leafs of gamal and Api-api used as raw material to produce the compost and its properties to adsorb Pb in fish culture media. The experiment design used a completely randomized design to determine the best level of gamal leaves and Api-api leaves compost, then followed by multiple comparison test to find the best type of compost to adsorb the Pb. The results showed that the best type of compost to adsorb the Pb in cultivation media was gamal leaf compost at 9 g/1. Water treatment with all kinds of compost and its level, low Pb content in fish meat, the survival rate and the growth, except the leaf compost gamal level of 5 g/1.

Abstract

Phytoremediation, an emerging cleanup technology for contaminated soils, groundwater, and wastewater that is both low-tech and low-cost to remove, contain, or render harmless such environmental contaminants as heavy metals, trace elements, organic compounds, and radioactive compounds in soil or water. Bangka Island has some environmental problem that caused tin mining activities. One of them is the formation of pits that have an impact on the carrying capacity of land resources and environmental quality. The aims of research were to identify some native aquatic plants from tin-mined pit and to test some selectable native aquatic plants for bioremediation on medium treatment. Bioremediation tested have been done using 4 selectable plants on 5 combinations of water and medium treatment. The experiment is conducted with 4x5 designs of random factorial pattern and three replications. The measured parameters were: contents of heavy metal (Pb, Cu, Zn) of water, plant canopy and root; fresh weight ratio of the root/canopy, total fresh weight plant; total dry weight plant; DO; and pH. Field surveys in several districts of Bangka (Pemali and Riding Panjang) found some potential aquatic plants for phytoremediation. There were 14 species from 11 genuses. Most of them were Cyperacea. They were species in Pemali and Riding Panjang pit ponds. The selectable plants which used for phytoremediation test were E. ochrostachys, L. articulata, S. cucullata, dan T. angustifolia The phytoremediation treatment showed 4 aquatic plants had good potential for phytoremediation. Based on the heavy metals measurements of Pb, Cu, and Zn, L. articulata was the best plant to accumulate Pb metal (317,35 ppm), and T. angustifolia was the best plant to accumulate Cu and Zn metals (43,55 and 167,25 ppm). Both were phytoaccumulation plants and using phytoextraction mechanism. The selectable plants could increase the DO value and pH rising on the medium treatment

Abstract

Social mapping of coastal communities in TWP Padaido was expected to provide a preliminary picture of the living conditions of the communities in coral reef management priorities location of COREMAP program. This study seeks to collect informations mainly from the focus group discussion (FGDs) and the study of literature both in Biak Numfor and Jakarta. The findings showed that “the three furnace system” e.g. the role of traditional leaders, churches, and government agencies are very dominant in influencing fisheries management rules. In TWP Padaido, the government through the program COREMAP primarily involved in providing policy support for implementing local regulations. In general, traditional systems have a positive impact on society such as sasi. This system can avoid disputes in the resources uses and provide a better incomes for fishermen in TWP Padaido.
