Abstract

This study was conducted to determine morphometric kijing taiwan at several locations in Minahasa District and North Minahasa regency and its association with the abundance of plankton and water quality. Sampling gravestone taiwan and water quality obtained from the four (4 ) locations: Rap Rap Village, BBAT Tatelu North Minahasa Regency, Paleloan and Tataaran II Village, Minahasa regency. Morphometric measurements kijingg taiwan include dimensional measurements and weighing of the shell. Measurement of shell dimensions include length , width , and thickness. Include the weighing of the weighing of the total, shell weight and wet weight of meat. Water quality measurements carried out directly at the sites include measurement of temperature, pH, dissolved oxygen and water base texture, while the identification of plankton carried in Pathology and Clinical Laboratory of Fish Diseases, Faculty of Fisheries and Marine Sciences, University of Sam Ratulangi. Morphometric measurements will be taken in any of 50 individual kijing taiwan each location. The results of morphometric measurements in multiple locations showed uniform size Tataaran II contained in the Village, the Village and Village Paleloan Rap Rap while in BBAT Tatelu uniformity of size only in size from 7-18 to 9-74 cm was caused by Taiwan in the pool because kijing BBAT Tatelu regarded as pest extermination so regularly done. Relationships shell length and total weight kijing taiwan to change at any time is influenced by several factors such as the condition of gonadal maturation , water quality and availability of food in the waters.

Abstract

Penelitian ini bertujuan untuk menetapkan dosis penambahan ekstrak daun ketapang dalam pakan untuk meningktkan. Ikan uji adah benih nila berukuran 5-8 cm dengan beratr ata-rata 2,93 g yang diperoleh dari Balai Perikanan Budidaya Air Tawar Tatelu. Bahan uji berupa Daun Ketapang  (Terminalia catappa) dengan dosis A= 0, B= 5 g/kg, C= 10 g/kg, D= 20 g/kg dan E= 40 g/kg  diberikan kepada ikan selama 21 hari. Ikan diberi pakan perlakuan dua kali sehari yakni pukul 09.00 am dan 16.00 pm dengan dosis pemberian 5%/berat tubuh/hari. Hasil penelitian didapatkan pertumbuhan terbaik dicapai pada kosentrasi ekstrak daun ketapang 5 g/kg.  Sebagai kesimpulan adalah ekstrak daun ketapang dapat digunakan dalam akuakultur untuk meningktkan pertumbuhan ikan.Kata kunci : Daun Ketapang, tanaman obat, ikan Nila,  A. hydrophila, budidaya ABSTRAKThe research aimed to  establish the accurate dose of catappa leave extract supplemented into feed to enhance fish growth.  The fish measuring 5-8 cm with an average weight of 2.93 g were obtained from Board of Freshwater Fisheries Aquaculture Tatelu. Catappa leave extract as much as A= 0, B= 5 g/kg, C= 10 g/kg, D= 20 g/kg dan E= 40 g/kg were added into feed and fed to fish for 21 days.  The fish wee fed twice  day at 09.00 am and 16.00 pm at 5% of body weigth a day.  Research result showed that application of 5 g of leave extract per kg of feed gave the best absolute and specific growth of fish.  Thus, supplementation of leave extract into fish feed was potential ti improve fish growth.Keywords: catappa leave, medicinal plant, Nile tilapia, aquaculture, A. hydrophila.
