Size Distribution and Growth of young Payangka Fish, Ophieleotris aporos (Bleeker) from Lake Tondano

The research was conducted at the location of Lake Tondano, Minahasa District.The young payangka fish, locally known as nike fish by fishermen of the area. This study aims to determine the size distribution, length-weight relationships and to know the captivity growth in the aquarium. The research is expected to be a source of information about the fish of young payangka (Nike) and be able to contribute on the efforts of nike fish management in Lake Tondano for the future. Sampling is done by using a triangular shaped trap (sibusibu) with a length of 4m, width of 1.30m (top), and a mesh size of 0.5mm. The length frequency distribution with the size mode appeared most during the first of observation was in the range of 13.5 to 15.4 class size and changed in size in the third week of the 19.5-21.4 class sizes. Later in the fifth week the mode is in the range of 15.5-17.4 class size and changes in size in the seventh week at the range of 23.5-25.4 class size. The length-weight relationship of the study was showed by allometric growth (b = 2.70; b <3) which means the length increases faster than weight gain. Absolute weight growth of 0.2532g was recorded and absolute length growth of 10.12mm for 12 weeks was observed as well. Growth of a relatively large weight gained with value of 0.067mg occurs between the seventh week and the eighth week.Keywords : Nike Fish, growth, Tondano ABSTRAKPenelitian ini dilaksanakan di lokasi Danau Tondano Kabupaten Minahasa.

The thyroxine has been known as a hormone that can increase fish growth especially in the larvae stage. The provision of hormone thyroxine on larvae fish can be conducted through dipping. Determination of dipping time are very important to increase growth. The purposes of this research are determining the optimum dipping time for the growth and survival rate of snakehead larvae. This research was done at Laboratorium Dasar Perikanan, Aquaculture, Faculty of Agriculture, University of Sriwijaya, Indralaya. The method used Competely Randomized Design (RAL) with five treatments and three replicates, with dipping time are 24, 27, 30, 33 and 36 hours. The parameters observed are the absolute length growth, absolute weight growth, survival rate of larvae and water quality (temperature, pH and disolved oxygen). The results showed that the duration of immersion in thyroxine hormone solution in snakehead larvae showed relatively faster growth on treatment (P5) with 36 hours of dipping time. While the regression test result showed the optimal growth of snakehead larvae at the time immersion for 27,92 – 29,49 hours. Thyroxine hormone increased the growth of snakehead larvae but has no statistically significant effect. The length of time of thyroxine hormone 24-36 hours with a dosage of 0.1 mg l-1 did not affect the survival of snakehead larvae. Water quality of maintenance media is still tolerance for supporting the growth and survival of snakehead larvae.

Mechanical Shock

It is the key to guide rock-breaking design and engineering practice for how to obtain a reasonable test indicator to assess the cuttability of the rock. Some sandstone samples were tested by using the linear rock cutting machine in the school of mining engineering, University of New South Wales (UNSW), Australia. The curves characteristics for the weight percent of the broken debris with the mesh size distribution were obtained through the screening statistics. Furthermore, the fractal dimension of the specimen broken debris was derived through theoretical calculations and statistical analysis. The results showed that the rock cutting fragmentation is of significant fractal features under the mechanical shock loads. The broken debris fractal dimension of the structural integrity specimens is bigger, the range of the fractal dimension is smaller and the broken debris size distribution is more even than that of the poor structural integrity specimens. The fractal dimension is the ideal test indicator to assess and analysis the rock-breaking degree.
