Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kepadatan pada pengangkutan dengan suhu rendah terhadap kadar glukosa darah dan kelulusan hidup ikan nila (Oreochromis niloticus). Penelitian dilaksanakan pada bulan April sampai Oktober 2016 di Laboratorium Basah dan Kolam Percobaan, Ciparanje Unpad. Metode penelitian yang digunakan yaitu metode eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan dan empat ulangan. Perlakuan berupa kepadatan ikan sebanyak 5 ekor/L, 10 ekorLl, 15 ekor/L dengan pemingsanan, serta 10 ekor/L tanpa pemingsanan sebagai pelakuan kontrol. Pemingsanan dilakukan dengan cara penurunan suhu air menjadi 10±0,1 ºC. Pengamatan yang dilakukan terhadap kelulusan hidup setelah pengangkutan, kadar glukosa darah, kelulusan hidup setelah pemeliharaan pasca pengangkutan. Hasil penelitian menunjukkan perlakuan dengan kepadatan 15 ekor/l menunjukan hasil terbaik, yaitu kelulusan hidup setelah pengangkutan 98,33 %, kadar glukosa darah 192 mg/dL serta kelulusan hidup setelah pemeliharaan pasca pengangkutan 88,33 %.

Abstract

Yustiati A, Andriani Y, Herawati T. 2017. Sustainable aquaculture development in floating nets at Cirata reservoir (West Java, Indonesia) through single-sex nilem fish introduction. Asian J Agric 1: 29-34. This research aims to develop a sustainable aquaculture system using single-sex nilem fish in trophic level-based farming and to analyze the feeding habits, types of meal and preference level of the feed in nilem farmed in Cirata Reservoir. In addition, it also aims to determine the fish's ability as a biocontrol agent for water cleaning by measuring the ability to utilize periphyton attached to the floating nets. Research conducted at the Laboratory of Ciparanje, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran and floating nets of Cirata reservoir. Observation of the performance of biological testing and food feeding applies the experimental design method of Completely Randomized Design (CRD) consisting 5 treatments and 3 replications. The five treatments include non-artificial feeding (treatment A), 1% feeding of body weight per day (treatment B), 2% feeding of body weight per day (treatment C), 3% of feeding of body weight per day (treatment D), and 4% feeding of body weight per day (treatment E). The results showed there was no difference in the survival and growth levels of the female single-sex fish given both commercial and non-commercial feed. The highest feed efficiency was observed in the 3% of commercial feeding treatment, amounting to 55.30%. The fish are herbivorous and generalist with trophic levels between 1.03% and 1.45% eating planktons for living. Fish fed with artificial food to 4% of the biomass still graze on phytoplankton as the main source of food, but adapt by changing the natural feeding and tend to be ineffective in utilizing the available food resources in the waters. During the study, the types and amount of periphyton attached to the nets have decreased. Higher commercial feeding level results in the higher density of periphyton in the floating nets.

Abstract

Osteochilus melanopleurus or kalabau fish is indigenous fish of the Kampar River,Riau. The information on morphological and meristical characteristics of this fish,however, is almost none. To understand the morphological and meristical characteristicsof the fish, a study has been conducted from April to September 2017. The fishwas sampled using fish trap and nets (1.15 cm and 5 cm mesh size). Twenty one characteristicswere measured using a Vernier calliper and then each character was comparedto Standard Length (SL). There were 96 fishes captured, consist of 59 males(160-355 mm SL, 100-1800 g BW), 22 females (310-515 mm SL, 850-4000 g BW)and 15 juveniles (80 -180 mm SL, 11.50- 194 g BW). In general, there was no differencecharacteristics in male and female fish. The distance between mouth lip to pectoralfin was around 51% of SL; dorsal fin to pelvic fin was around 39% of SL; dorsalback to caudal bottom was around 28 % of SL and anal fin back was around 21 % ofSL and TL was around 130% of SL. Meristical characteristics of fish are as follows: D.II. 151/2-191/2 ; P. I. 14-17; V. I.8; A.II.61/2; C.VI.6.II. The sex of juveniles, however,could not be identified as gonad in this young fish was not developed yet. Based ondata obtained, it can be concluded that the relative growth of all characteristics measuredwere almost isometric to SL.
