“…The suitability of Tubifex as food for catfish larvae could also be because of their very high digestibility (Mann, 1935 as cited by Ponnuchamy et al., 1981; A.D. Evangelista and S. F. Baldia, unpubl. data) and high nutritive value (Galinat, 1960 as cited by Ponnuchamy et al., 1981). Moreover, this could be associated with the fact that these organisms thrive in areas resembling the natural habitat and spawning ground of the catfish (Shim, 1986).…”

Comparison of some live organisms and artificial diet as feed for Asian catfish Clarias macrocephalus (Gunther) larvae

Experiments were conducted to evaluate the efficacy of five live organisms (Artemia, Brachionus calyciflorus, Chironomus plumosus, Moina macrocopa and Tubifex sp.) and an artificial diet (40% protein) in the larval rearing of Asian catfish Clarias macrocephalus. The larvae were fed three times daily starting at the onset of exogenous feeding. Results showed that the catfish larvae utilized the live organisms more efficiently than the artificial diet. The Tubifex-fed larvae consistently showed the highest growth rate. In trial 1, length increment (64.9 mm), weight gain (3192 mg) and specific growth rate (13.1%) after 8 weeks of feeding were significantly higher (P < 0.05) in catfish larvae given Tubifex than those in all other treatments. In trial 2, length increment after 4 weeks of feeding was highest in larvae fed Tubifex (22.9 mm) although it did not significantly differ from that of larvae given Moina (21.0 mm). However, weight gain of larvae fed Tubifex (253.0 mg) was significantly higher than that of larvae fed Moina (171.6 mg). The specific growth rate was highest for larvae fed Tubifex (15.0%) followed by larvae fed Artemia (14.5%), Moina (14.4%) and Chironomus (12.0%). Survival rates of the catfish larvae ranged from 9 to 39% after 8 weeks in trial 1 and from 26 to 83% after 4 weeks in trial 2. The present results suggest that Tubifex is an excellent food and a potential substitute for Artemia in the rearing of catfish larvae.

This study aims to determine the effect of giving several types of natural feed and evaluate the best type of feed for thebody length of super red arowana fish (Scleropages formosus). This study used the Complete Randomized Design (RAL) method with 3 treatments and 3 repeats with 3 types of natural feed, namely crickets (A), Hong Kong caterpillars (B), and white shrimp (C). The maintenance of super red arowana fish is carried out for 70 days with a frequency of feeding three times a day and given satiation (ad satiation). The results showed that the feeding of crickets for super red arowana fish gave the highest length of 0.84±0.08 cm, the highest specific growth rate of 6.00±0.59%, and the survival rate (SR) at the end of the study was 100%. The results of measuring water quality parameters, namely temperatures of 28.7° C -30.4 °C, pH 7.97-8.14, and dissolved oxygen 4.6-5.4 mg.l⁻¹, are in the optimal range for the maintenance of super red arowana fish.

“…Food intake, assimilation efficiency and gross and net conversion efficiencies (K1 and K 2 : %) were calculated following the procedures detailed by Katre and Reddy (1976) and Ponnuchamy et al (1981b). The production of new tissues (= conversion) was calculated by adding the exuvial weight to the gain in total weight of the prawn and the actual growth was calculated by subtracting the exuvial weight from the gain in total weight and expressed as "yield".…”

Effects of different ration levels on survival, moulting and food conversion in two freshwater prawns

Effects of different daily rations of the oligochaete worm Tubifex tubifex on survival, moulting and food conversion of Macro brachium lanchesteri (Palaemonidae) and Caridina weberi (Atyidae) have been described. Moulting is a metabolic necessity for either species and occurs even at the expense of organic reserves of starving prawns. The geometric derivation of the growth-feeding rate relations in M. lanchesteri indicated that, 88, 162 and 204 mg live food/g live prawn/dav represent the maintenance, optimum and maximum feeding rates respectively. The corresponding values for C. weberi were 96, 236 and 3% mg. Food availability has a marked influence on the food partitioning and biochemical composition of either species.
