Abstract

Research about comparative study of food types of fish Keperas (P. binotatus) inthe river of Aek Pahu Tombak, Aek Pahu Hutamosu and river of Parbotikan DistrictBatang Toru that have aim to determine the types of food in fish and feeding habit ofPuntius binotatus. The research was occured in the river of Aek Pahu Tombak, AekPahu Hutamosu dan river of Parbotikan District Batang Toru in January-March2013.The method of fishing is used by elektrofising gear 12 volt. The analysis of dataincludes the relationship of fish length and weight, condition factor, bulk index (IndexPropenderance), the index of food options, wider food niche, and niche overlap of food.The result showed that fish keperas (P. binotatus) eat 6 groups of organisms that arepresent in all research station, types of Bacillariophyceae is the main food,Chlorophyceae, Monogononta, Ciliophora, and detritus as a supplement food, andCyanophyceae as additives food.

Abstract

Research about content of heavy metals in various fish species have been done inBatang Toru River, Aek Pahu Tombak and Aek Pahu Hutamosu district South Tapanuliin March-April 2013. The purpose of this study was to determine the content of heavymetals that accumulate in the body of fish and the water, and to determine the waterquality of River Batang Toru, Aek Pahu Tombak and Aek Pahu Hutamosu. The methodfor determining the location of sampling for fish sample is "Purposive RandomSampling" in 6 (six) observation stations. Analysis of heavy metal analyzed on fishmeat and water using Atomic Absorption Spectrophotometric (AAS). The resultsshowed that the content of heavy metal in fish body didn’t exceeded the qualitystandard by SNI/7387/2009. Content of heavy metals accumulated in the water didn’texceeded the quality standard based on Regulation No.82 of 2001. Aek Pahu TombakRiver has a very good quality of water but Batang Toru River and Aek Pahu Hutamosuhave a good quality of water.
