[Cited 30 March 2018]. Various scientists have described the life history of the Indian Major Carp. Keywords: Cirrhinus mrigala, Histophysiology, Oreochromis niloticus, Pancreas, Wallago attu Introduction The pancreas, a compound gland, consisting of exocrine and endocrine tissue is present throughout the entire vertebrate series with various degrees of Rome. In the larval stage, they mainly feed on zooplankton such as nauplii, rotifers, cladocerans, and copepods (Hora and Pillay, 1962). The pH of in the intestinal fluid in the intestinal bulb ranges from 6.8-7.1, but decreases to within a range of 6.2 to 6.5 in the hind gut (Figure 5). A feeding trial of 60 days was conducted to delineate the effect of dietary synbiotic on maximum growth, body composition, digestive enzyme activity and subsequently gut microbiota in Cirrhinus mrigala fingerlings. Seven different mixed feeding schedules were evaluated in Cirrhinus mrigala fingerlings having mean body weight (BW) of 2.84g employing a low (L) protein (20.29%) diet and a high (H) protein (40.12%) diet, feeding @ 3% Bwd -1 for 45 days. Caudal fin homocercal and deeply forked. Scales large and cycloid. They are predominantly planktonic feeders but they also eat rotten plants or plant parts (Jhingran and Khan, 1979). Body bilaterally symmetrical and streamlined, its depth about equal to length of head; body with cycloid scales, head without scales; snout blunt, often with pores; mouth broad, transverse; upper lip entire and not continuous with lower lip, lower lip most indistinct; single pair of short rostral barbels; pharyngeal te… Contact us  | Terms and Conditions |  Scam Alert, Aquaculture Feed and Fertilizer Resources Information System. Protein digestion occurs at pH 7.0 to 7.1 in the midgut. Fecundity varies from 1 – 2 x 104 depending upon the size of the fish. Morphological specializations of the buccal cavity in relation to the food and feeding habit of a carp Cirrhinus mrigala: A scanning electron microscopic investigation Madhu Yashpal Skin Physiology Laboratory, Centre of Advanced Study, Department of Zoology, Banaras Hindu University, Varanasi, Uttar Pradesh 221 005, India Copyright © 2020 Elsevier B.V. or its licensors or contributors. With the survival levels lying in the narrow ranges of 44.01–46.71% in mrigal and 53.03–56.65% in rohu, no significant differences (P > 0.05) were recorded between the treatments. Lateral line continuous to centre of caudal fin base (Figure 1). Feeding frequency of one, two and three times daily as three treatments were evaluated against a control without feeding in triplicate tanks in two separate trials of 15 days each. A feeding trial was carried out to assess the effect of dietary chromium supplementation on apparent nutrient digestibility coefficient (%) of gelatinized and non-gelatinized corn in Cirrhinus mrigala fingerlings for 90 days. They also feed on rotifers, insects and their larvae, crustaceans, bryozoans etc. Present study is an attempt to elucidate the feeding habits of the carp, viz. Morphological specializations of the buccal cavity in relation to the food and feeding habit of a carp Cirrhinus mrigala: a scanning electron microscopic investigation. Map showing the location of Harike wetland Figure 2.Scanning electron micrograph of scale of Cirrhinus mrigala taken as control showing regularly placed lepidonts on circuli. Figure 1. Their body is bilaterally symmetrical and streamlined. Feed on plankton, but also grazes on algae. (A) Metaphase stage (control), (B) karyotype of the chromosomes of C. mrigala without butachlor exposure. The alimentary canal becomes functionally complete on the third day after hatching, when it is a simple, nearly straight tube. Add Documents. C. cirrhosus has four barbells whereas mrigala has only two barbells; dorsal branched rays are 15-16 in cirrhosus vs. 12-13 in mrigala.” From Simonsen et al. Hatchlings of mrigal normally remain in the surface or sub-surface waters, while fry and fingerling tend to move to deeper water. The mrigal carp (Cirrhinus cirrhosus), (Bengali: মৃগেল, romanized: mrigél) also known as the white carp, is a species of ray-finned fish in the carp family.Native to streams and rivers in India, the only surviving wild population is in the Cauvery River, leading to its IUCN rating as vulnerable. (iv)Karyotype was comprised of 15 pairs of metacentric chromosomes. Cirrhinus mrigala with other major carps is commonly cultured in sub-continent.

In this study, food and feeding habits of selected … Protease concentrations slightly varied but variations were prominent from species to species. Its herbivorous feeding habit has been reported by most of the earlier researchers [30-33,36-39]. A study of the food and feeding habits of fish is very important in any Fisheries research programme since feeding habitats are related with the digestive system of the fishes which differ from one species to another. The bottom feeder and omnivorous feeding habit of Cirrhinus mrigala was confirmed by the index of preponderance and grading of various food items. Pectoral fin… 41236).Please send references, or more studies are needed. Anal fin not extending to caudal fin. Cultured Aquatic Species Information Programme. Hatchery produced spawn were stocked at the density of 10 million/ha. Jhingran (1991) has summarised the feeding habits of several Indian species viz., Catla catla, Cirrhinus mrigala, Hypophthalmichthys molitrix and Puntius species. The bottom feeder and omnivorous feeding habit of Cirrhinus mrigala was confirmed by the index of preponderance and grading of various food items. A six-week experiment was conducted in six glass aquaria to study the feed conversion ratio (FCR) of Cirrhinus mrigala fingerlings fed on cotton seed meal (35.69% CP), fish meal (50.41% CP) and barley (9.98% CP). Mrigal is widely cultured along with catla and rohu. Mouth terminal and wide, lips without fringe, upper lip not continuous with lower lip. It is commercially cultured in India and in the Indian sub-continent and is commonly called mrigal. Fish meal is rich (2005): “The Indian major carp species [Catla catla, Cirrhinus cirrhosus, and Labeo rhoita] are known A 6 kg female can lay a million eggs (of 1 mm diameter) (Ref. Yadav (1997) reported the food and feeding habits of Catla catla and Labeo rohita. The alimentary canal remains shorter than the body length up to 7 days after hatching and thereafter increases at a much faster rate, becoming longer than the body (Kamal, 1967). Feeding Habit Cirrhinus reba is a bottom feeder [5,30-35]. In the present study, the feeding habit and preferred food contents of Cirrhinus mrigala from Ukai reservoir of Gujarat was discussed with reference to index of preponderance. Updated 21 February 2006. In natural waters breeding occurs during the south-west monsoon season in shallow newly inundated wetlands and or river side pools. Spawning occurs in marginal areas of the water body with a depth of 50-100 cm over a sand or clay substrate. Mrigal - Cirrhinus mrigala (Hamilton, 1822) [Cyprinidae] Taxonomic and biological features: Distinguishing characters Body elongate with depressed and obtusely rounded snout (Figures 1 and 2). The Mrigal fish is a species of ray-finned fish in the carp family. A study of the food and feeding habits of fish is very important in any Fisheries research programme since feeding habitats are related with the digestive system of the fishes which differ from one species to another. Lateral line continuous to centre of caudal fin base (Figure 1). monthly fluctuations in feeding activity and gastrosomatic index (GaSI) is in agreement with each other. Mrigal have a narrower range of acceptable foods, being bottom-feeders living mainly on decaying vegetation. The effect of feeding frequency on growth, survival and feed utilization in mrigal, Cirrhinus mrigala, and rohu, Labeo rohita, during raising fry were studied in 50-m 2 cement nurseries provided with 10 cm soil base. distinguishable in the Cirrhinus mrigala. Scales large and cycloid. supplementation increased feed palatability and growth. It is a bottom-feeding fish and often referred to as a scavenger. Key words: Feeding stimulants, Cyperus rotundus, Cirrhinus mrigala, Aspartate aminotransferase, Alanine aminotransferase INTRODUCTION Most aquaculture waste originates from the feed, which constitutes a major part of waste output in any fish farming operation (Cho et aL, 1991}" Consequently, 93245). It is also called One hundred eighty … By continuing you agree to the use of cookies. Issue The species Cirrhinus mrigala (Hamilton, 1822) is considered as valid in Eschmeyer (CofF ver. Yadav (1997) reported the food and feeding habits of Catla catla and Labeo rohita. Similar to all carp species, the mouth of mrigal is devoid of any teeth on the jaws. Hypophysation is practiced to induce spawning under captive conditions. Yadav (1997) [15] reported the food and feeding habits of Catla catla and Labeo rohita. Hanumantha Rao (1974) reported first maturity of mrigal at 349 mm, when the fish are 2 years old. Fry of this species exclusively feed on the animalcules and water fleas; while fingerlings consume in the order of preference the vegetable debris, unicellular algae, detritus and mud [38]. Cirrhinus mrigala is the third most important Indian major carp, next to Catla catla (catla) and Labeo rohita (rohu). Ahmed (1944), Alikuni and Rao(1951), Alikuni (1956) described the early stages of minor and medium sized carp, such as Labeo gonius, L. bata and Cirrhinus reba. Sinha GM.
