Daftar Isi:
- This research are carried out in July – August 2008, placed in Indoor Fishery laboratory, Animal Husbandry Faculty – Fishery Muhammadiyah University Malang. Purpose of this research are to fins out the giving of frozen blood worm (Chironomus sp.) with different percentage to the speed of growth, FCR and the lifelines of the origin of freshwater lobster (Cherax quadricarinatus). Results of this research are hoped giving information to the society or practitioner who involved in cultivation of freshwater lobster, about the use of a blood worm (larva Chironomus sp.) as the woof of freshwater lobster. This research is using experiment method by data taking using direct observation. Design of research that used is complete random design (RAL) with 4 treatments and 3 times repeat. The treatment giving frozen blood worm (Chironomus sp.) to the origin of freshwater lobster (Cherax quadricarinatus) with different percentage, those are 7% from biomass weight (treatmen A), 9% from biomass weight (treatmen B), 11% from biomass weight (treatmen C) and 13% from biomass weight (treatment D). Result from random examination shows that giving frozen blood worm (Chironomus sp.) in different percentage gives significant impact to the growth of origin of freshwater lobster (Cherax quadricarinatus) with account F are 4,95 (Table F 5% = 4,07 and 1% = 7,59) that means refuse H0 and accept H1. From this research gained growth speed means specific (SGR) origin of freshwater lobster during this research were in about 6,99 – 7,50% BW/day lobster’s age are 10 days. For the treatment D (13%) shows growth speed means specific (SGR) that is the best with 7,50% BW/day, followed by treatment B (9%) 7,44% BW/day, treatment A (7%) 7,13% BW/day, and the lowest treatment are treatment C (11%) 6,99% BW/day. Result from random examination shows that giving frozen blood worm (Chironomus sp) in different percentage gives significant impact to the Food Conversion Rating (FCR) origin of freshwater lobster (Cherax quadricarinatus) with account F 17,09 (Tabel F 5% = 4,07 and 1% = 7,59). The best Food Conversion Rating (FCR) was in treatment A (7%) with value 13,2 gram and the lowest are treatment D (13%) 24,98 gram. Treatment B (9%) are 24,23 gram, then treatment C (11%) are 16,92 gram. Resulit of random investigation shows that treatment give indifferent impact to the lifelines (SR) origin of freshwater lobster (Cherax quadricarinatus) with account F are 0,90 (table F 5% = 4,07 and 1% = 7,59). From this research gained value of lifelines (FR) origin of freshwater lobster (Cherax quadricarinatus) during this research are 70-100%. Result of measurement of water quality as the support parameter during this research is homogeny and still in the value that are suitable to life and the growth of origin of freshwater lobster (Cherax quadricarinatus) in temperature around 22,23 – 22,55 C and dissolved oxygen around 7,82 – 8,01 mg/1, pH around 7,70 – 7,79. From this result can be concluded that giving frozen blood worm (Chironomus sp.) in different percentage (7%, 9%, 11% and 13%) giving significant impact to the Speed Growth Ratio, giving significant impact to the Food Conversion Ratio and did not give significant impact to the lifelines (SR) to the origin of freshwater lobster (Cherax quadricarinatus). Based on this research hoped in increasing good speed growth in raising freshwater lobster (Cherax quadricarinatus) the food is should be natural food, fresh blood worm (Chironomus sp) or in life based on the best doses and also need improvement in cultivation of blood worm (Chironomus sp.) as an alternative food for freshwater lobster (Cherax quadricarinatus).
