Abstract

The surrounding community activities in the area of milkfish ponds include residential and household waste so that it will affect the water source used for milkfish farms (Chanos chanos Forskal). Due to changes in water quality, it will be known how the condition of pond water quality will affect the abundance of phytoplankton and the growth of milkfish (Chanos chanos Forskal). This study aims to determine the relationship of plankton abundance with the growth of milkfish (Chanos chanos Forskal) in traditional ponds. The method used is the descriptive method. The study was conducted in March - May. The results of the regression analysis for plankton abundance found a relationship that affects a specific growth rate of 83% and 17% influenced by other factors. The correlation coefficient (r) obtained is 0.91 so that it can be said that the abundance of plankton influences the specific growth rate classified as strong. Based on the value of b = 0.0156x (positive relationship) means that if plankton abundance rises the rate of growth also increases by 0.015. If the plankton does not exist or 0 then the rate will decrease by 94.

Abstract

The province of South Kalimantan has the largest peat swamp that is named Danau Panggang Swamp with an area of 5,390.7 Ha. This swamp has ecological, economic and potential functions of a large fishery resource. The purposes of this study are to evaluate the exploitation rate of Snake Head Fish (Channa striata) in Danau Panggang Swamp, by population dynamic analysis using FISAT program of Von Bertalanffy method.  The results showed that the growth pattern of Snake Head Fish (Channa striata) has the tendency to grow negative allometric with 63.4 cm of long infifer (L¥), growth rate (k) 0.15 per year, theoretical age at the time of the fish is equal to 0 (t0) is -1.48257 years. While the natural mortality rate (M) was 0.43, the mortality rate due to catch (F) of 0.69/year and the total mortality rate  (Z) of 1.12/year, and the rate of exploitation value E = 0.62.  These results indicated that the exploitation rate of Head Snake Fish (Channa striata) in Danau Panggang swamp has a tendency to overfishing.

Abstract

Marine area which is planted by seagrass called as seagrass beds. Seagrass is one of the typical ecosystems in marine waters. Bangka Belitung Province is one of the areas in Indonesia that has seagrass ecosystem. This study aims to determine the diversity, density, and coverage area of seagrass beds in the waters of South Bangka Regency. The research was conducted in Tukak, Tanjung Kerasak, and Tanjung Kemirai. The data is collected using quadratic transect method and also data of physics-chemical parameters such as temperature, salinity, pH, depth, velocity and water substrate. The results of the research showed that 7 species of seagrasses in South Bangka Regency are Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis, Enhalus acoroides, Thalassia hemprichii, Syringodium isoetifolium and Halophila minor. Seagrass in Lempeng waters which has the highest density is Cymodocea serrulata, about 58 ind/m2. The highest frequency of seagrass species in Tukak is Thalassia hemprichii about 1%. Seagrass species of Cymodocea serrulata has the highest cover percentage in Lempeng waters about 29.56%.
