Tubifex worm are often used as a live food for fish, especially tropical fish and certain other freshwater species. Contractile heart is found in the 8th segment. Clitellum is formed in the 11th and 12th segments.Ħ. Setae Forked and hair-like in dorsal bundles and only forked in Ventral bundles.ĥ. Each body segment except the last few are provided with four bundles of setae on the dorsal and ventral sides.ģ. Tubifex is a small slender worm, measuring about 4 cm in length and reddish in color.Ģ. The animal lives in tubes made up of mud and minerals glued together by mucin.ġ. Habit and Habitat: Tubifex is a fresh water form, occurs in patches on the muddy bottom in the freshwater ponds and lakes. Bring home, pour into a bucket, filled with 3/4 full, stir and let the worms settle in the centre, from there, i pour out the water, till abt. Arenicola is generally used as bait in fishing.Īrenicola can be beneficial by negatively impacting the population of small rodents and insects. Bro, previously what i did was, that i buy a whole packet for abt. Posterior region or post branchial region is much thinner consisting of a variable number of segments devoid of parapodia setae and gills.Ĩ. Middle region or branchial region comprises thirteen segments bearing parapodia and branched gills.ĥ. Body is divisible into three regions, anterior middle and posterior.Ĥ. Body is stout, elongated, cylindrical worm- like measuring up to 20 to 25 cm in length and brownish or greenish in color.ģ. Arenicola is commonly known as lug warm or lobe-worm.Ģ. It is found in Mediterranean and European shores.ġ. Habit and Habitat: Arenicola is a marine worm that lives in U-shaped burrows of sand and mucus. auratus brooder fed with bioencapsulated Tubifex was seen compared to control group fed with depurated Tubifex.Distribution: Arenicola is distributed in Europe and the U.S.A. Likewise, a significant improvement in total wet weight gain (p<0.009), FCR (p<0.01) and SGR (p<0.04) of C. auratus fed with bioencapsulated Tubifex showed less (55%) signs of tail/fin rot. The survival was significantly higher (p<0.05) in bioencapsulated Tubifex fed group (44%) than in control (22%). auratus fries were infected with Pseudomonas fluorescents, the bioencapsulated Tubifex fed group resisted the infection.
was recorded at a level of log 5.11/g on the 90th day of experimentation. None of the bacteriological parameters of the fish gut between the experimental and control groups differed significantly (p>0.05). in Tubifex showed significant improvement in total wet weight gain (p0.05) in bioencapsulated Tubifex fed group. auratus fries when fed with bioencapsulated Lactobacillus sp.
in live fish food organism Tubifex for use in the culture of gold fish Carassius auratus. Abstract An attempt was made to feed bioencapsulate Lactobacillus sp.
