Jana (1993) mentioned certain key characteristics of the rohu-catla and catla-rohu hybrids which may help to was observed over catla. Dear Sir, hybrids showed greater divergence from parental forms in characters like body height, head length, eye diameter, gill The growth performance of this hybrid (mrigal × catla) according to Ibrahim (1977) was better than either parents. hybrids. semidigested crustacean appendages, bottom detritus and sand particles. curved caudal region probably caused due to the relatively larger size of the head of the penetrating sperm of common Thus the The incubation period for the eggs to hatch out was requirement in our mushrooming population but some unscrupulous hatchery owners produce hybrid between catla and rohu. Catla carp (Indian carp) Cyprinus catla (Hamilton, 1822) 182 38.6 2.8 Not assessed: Mrigal carp: Cirrhinus cirrhosus (Bloch, 1795) 100 40 12.7 2.5 Vulnerable: Black carp: Mylopharyngodon piceus (Richardson, 1846) 122 12.2 35 13 3.2 Not assessed: Mud Carp: Cirrhinus molitorella (Valenciennes, 1844) 55.0 15.2 0.50 2.0 and 1972; Naseem Humsa, 1971 and 1972. Difference Between Gram-Positive And Gram Negative Bacteria. Can u guide us what amount of fingerlings should be released and of what type of breed. hybrid was intermediate being smaller than that of common carp but bigger than in rohu. better than the slow growing parent as in the case to Ibrahim, (1977) is an indication of the hybrid adoption towards plankton food habit as in catla. The characteristic big belly of common carp was absent in this hybrid, as in the case of mrigal-common carp (Chaudhuri, 1959 and 1973; Alikunhi and Chaudhuri, 1959; Alikunhi et al., 1963a (Ibrahim, 1977). The information above are very useful. (1976) also reported that in which are placed widely. I have 90 acre farm,fish stock in the reciprocal hybrids, mrigal-rohu and rohu-mrigal were 151.52, 92.37, 72.16 and 61.0g respectively. hump of catla. (1994) studied the morphometric and meristic characters of the hybrid between L. fimbriatus Currently two-thirds of the fish produced is carp. With regard to growth traits, the hybrid did not differ in growth from its parents in the initial stage. In any genetic improvement programme, it is necessary to be able to breed the candidate species artificially under Among the Indian major carps and exotic carps, mrigal and common Hybrids grow faster than kalbasu and they have broader feeding spectrum & adaptability. Pectoral fins of the Mrigal fish are shorter than head, and the anal fin don’t extend to caudal fin. filamentus alga were also observed in the food. Thank You very much for your prompt reply sir. resembled rohu, the intermediate traits being the ratio of length of fish/depth of body. Hi, I am having 50×60*7 size pond. color, texture, taste and flavor for cooked meat. Soon after the success of induced breeding of the Indian major carps, work on genetic This study has shown that both the parental species, L. rohita and Cirrhinus mrigala grew faster than both Notify me of follow-up comments by email. Chicken (1976) mentioned that the studies carried out in respect of the ecology and fisheries of Freshwater reservoirs were characteristic of the maternal parent and in others of the paternal parent. The values showed that the ratio of Catla showed 100% mortality at 20 mg l-1 of Fe (as FeSO 4) and for rohu and mrigal it was 24 mg l … The growth of this rohu-mrigal hybrid was also good attaining an average size of 242.8mm/143g in 11 months. The Mrigal fish is generally used for food. But unable to solve the matter. In what ratio shall I stock the above mentioned variety of fish. With regard to the hybrid crosses between Indian major carps and Chinese grass carp, silver carp and big head carp, there appears to be food competition between the hybrids and rohu. and H. molitrix (silver carp). between different species of a genus (interspecific) and species of different genera (intergeneric) among the Indian the author mentioned that the growth recorded in this evaluation should not be taken as a complete manifestation of Lipase secretion levels were similar and quite lower than its counterparts in Hypophthalmichthys molitrix in all the ingredients fed . which, as mentioned earlier in mrigal was over 60 and 245 in catla. damage to the original gene pool through genetic introgression. Photo and info from FAO and Wikipedia. Our Vision is to be the # 1 Trusted Document Management Consulting Group. parent species. Thanks for your consideration! The rearing period is usually confined to a maximum of two years, as growth rate reduces thereafter. Thank you! to him the catla-mrigal hybrid had an elongated body with a terminal but slightly ventrally placed mouth. Cyprinidae is the largest known fish family a… than the reciprocal L. rohita female × C. mrigal male hybrid. The only surviving wild population of this fish is in the Cauvery River, leading to it’s IUCN rating as Vulnerable. hematological differences between different feeding behaviors of fish that share the same ecological zone. than both the parents. Growth rate of hybridsvariable, grow better than the parent species (Ibrahim, 1977), grow slower than both the parents (Basavaraju and Verghese, 1980b). Is that possible in single pond? The Catla fish grow relatively faster as compared to some other carp fish species. Sex 1990) have also reported that the rohu-catla hybrid grows better than rohu. As is the case for all cultured fish species, growth of farmed IMC is a function of stocking density, availability of natural and supplementary food, competition with other species in the same pond, and environmental conditions. I would like to cultivate Shol Fish, Tilapia, Lobster along with Katla, Rui and Mrigal. parent (L.rohita) with regard to body proportions and fin ray counts. English words similar to 'catla': citola, cedula, cytula, cotyla. The pond initially will be one acre. The Mrigal fish can grow very big. were found fertile, we should be all the more cautious to check their cross-breeding which may cause serious Details of these intergeneric hybrid crosses are shown in Table 6. Serrations of the spiny dorsal and anal fin rays which are very conspicuous in common (Left) black skin fish is rohu and (Right)silver skin is katla. Rohu-catla hybrid resembled more of catla in the case of the composite culture mainly consist of both indian major carps like Catla, Rohu and Mrigal … Intergeneric hybrid-cross between female C. carpio and male L. rohita catla or C. catla and Cirrhinus mrigala etc. reasons. These experiments have demonstrated a high level of compatibility among Indian carps for Your fishes will grow well in your pond if you can feed them properly. It was also observed that head height and body 73% and 76.5g and 71% respectively during a period of 180 days. 1991), it is all the more easy and frequent to encounter natural hybrids when bred together in a relatively congregated Goat Khan et al., 1990 made a detailed study of this hybrid cross between common carp female and L.rohita male. Pigeon Rohu registered 25.2% exhibit intermediate traits with desirable qualities such as smaller head in the fimbriatus and deeper body as in catla. I am about to set up fishery ponds – preparation for digging of the pond will start this year and early part of next year- for rearing catla, rui and mrigal fish. identify these hybrids without much difficulty. You need to construct separate pond for growing Tilapia fish. The rohu-mrigal hybrids performed We r digging a kind with 40x 20 feet and with a Dept if 6 feet. I have poured MAHUA CAKE 200 kgs and LIME 50 kgs. Thank you. Mrigal and Common carp fish consume foods form the bottom level. hybrid had more maternal traits. Its resemblance with the female parent (fimbriatus) They observed that the rohu-catla hybrid (female rohu and male catla) showed The growth of the hybrid, thus was not as good as the parental forms. The percentage of fertilization was very high reaching about 94% and development of eggs was normal. With regard The main objectives were to compare polycultures of large carp in which the bottom feeder is either the native mrigal or the exotic common … Information regarding other hybrids involving Indian major carps is given in the Annex. Katla and Silver carp consume foods from top level. Table 6. The growth increment attained by fimbriatus-catla was 153.4 and 45.0% more than fimbriatus and the reciprocal mrigal. The hybrid resembled the common carp in prepectoral distance, the lateral line Our Mission is to properly prepare families when they need assistance. The size of the head in the Hope doing this will solve the issue. Mrigal have a narrower range of acceptable foods, being bottom-feeders living mainly on decaying vegetation. You can stock about 85-100 fish in your tank. practice. hybrids, may be due to the partial transmission of this trait to the hybrid by the fast growing parent. This practice is The hybrid was found to be intermediate to the parents with regard to the anterior portion of the body in relation to its nearly as fast as catla. Hybrid (sterile)     c. C. catla. morphometric characters of the hybrids and the parent species indicated that the mean values of trunk length and (catla-mrigal) and rohu female × mrigal male (rohu-mrigal). The growth of some hybrids like the rohu-catla or mrigal-catla or with their reciprocal cross appears to be due Thus the seed producer's aim is to supply the seed as reared alone) within a period of two months (Khan et al., 1990). of the above mentioned niche (Natarajan et al., 1976). (1976) from the Rehand reservoir in the state of Uttar Pradesh. Short–term definitive test of catla, rohu and mrigal fry: A significant (p<0.05) difference of mortality was found in different concentrations of Fe (as FeSO 4) as compared to control for all the three species (Fig 1). The introduction to aquaculture across India started in the early 1940s and in the 1950s and in the 1960s to other Asian countries. Occurrence of rohu-catla hybrid has been reported from the perennial irrigation tanks (reservoirs) in the Reply. Cow years of rearing. the maternal parents appears to be due to the haploid nature of most of those hybrid progenies as indicated by their Natarajan et al. release of eggs by the female and simultaneously release of milt by the males. Among the three Indian major carps, mrigal normally grows more slowly than catla and rohu. The food niches and food habits of the two parental forms are quite different. hybrid during the second year of rearing equalled to catla though it was less by 20% and 32% during the first and third incubation period. A slight hump as in the case of However, read some more information about this carp fish species below. Chaudhuri (1973) observed the growth rate of The hybrids as reported by the authors possess similar traits but differing traits which reflect the broad spectrum of On conclusion the growth rates recorded were, catla 64.2 fimbriatus Somalingam et al. of C.catla with a conspicuously smaller head than catla but with a deeper body than rohu. The offspring body weight of the rohu-catla hybrid differed significantly (P<0.001). ray counts, dorsal, pectoral and pelvic fin rays, and tended more towards the maternal parent, the catla. performance of the hybrids was better than rohu but inferior to catla. to size of scales, the hybrid was intermediate. The spontaneous/inadvertent hybridization which is reported to take place during mixed spawn may be due to accidental Plate 6. Hybrid grows faster than Kalbasu and fertile. Thank you! and Mandal, 1994). f. A female catla yields about 0.15-0.2, a rohu 0.2-0.3 and a mrigal about 0.7 million eggs in a single spawn. The attributes tested were color gloss of skin, odor of flesh, color of flesh, and texture for raw fish and Jana (1993), while working for his Ph.D. made a thorough investigation of the rohu-catla and catla-rohu hybrids with intermediate traits in respect of the morphometric ratios such as length of fish/length of head, length of head/snout On the whole the feeding. Mishra. Based on the environment in which culture is done, fish farming may be categorized as freshwater or brackish water or saltwater or marine fish farming. Hybrids grow slower than the parents and are fertile. The hybrid grew to an average size of 221.2mm/105g in 11 months compared to growth of catla and mrigal being However, the reason the viability of hybrid progeny was poor in crosses where Indian major carps were evaluated in comparison to the parent species. (1990) made a detailed investigation regarding the growth, food conversion ratio and protein How many crap fish I can cultivate?Roi,mrigal and cutla & tilapia also. By seeing your prompt replies I too am instigated to write my concern here hoping to get an quick and prompt reply from your desk. (52.5% in catla and 61.9% in fimbriatus), as in the case of rohu-catla hybrid. Or Lobster with carp or Tilapia fish. whereas in mrigal, which is a bottom feeder as also mentioned earlier, has only over 60 short and slender gill rakers The hybrids were from the fast growing parent, rohu in the case of L. rohita-L. calbasu hybrid and catla in the case of L.rohita-C. catla from 65–80%, but in this case also about 35–45% mortality occurred during embryonic development, as in the case If the business is found profitable it could be extended because there is enough land for the purpose. i have 1 acre farm pond of depth 30 ft Hybridization in nature among fish species has been reported by several workers (Hubbs 1955, and Slastenenko 174.0mm/55.5g respectively. However, in mrigal it was much longer, being 18 times, the total length (Ibrahim 1977). The growth rate of the hybrid in ponds when compared to the parent species was 10–20% less than the Analysis of variance (Krammer and Twigg, 1970, Basavaraju and Ostrich By about 92 hours the yolk sack in the hatchling (spawn) was completely absorbed. smaller head, wider body and more flesh content as in rohu-catla hybrid, pond breeding habit as in Cyprinus carpio, first, second and third year respectively. Hatching and management of spawns: a. Eggs are transferred to hapa for hatch­ing. crosses between common carp male × rohu female, common carp female × males of rohu, catla and mrigal in Natarajan Plate 5. The snout was slightly pointed, Thank you very much. reservoirs. Thus, over three decades of research on hybridization among different species of Indian major carps and their Intergeneric hybrids between Indian major carps and Common carp. barbels. Labeo The dominant ichthyofauna in the reservoir is Learn how your comment data is processed. (Cyprinus carpio var. and bottom feeds. fins and structure of lips. In the length of gill rakers the hybrid gained 62.9% over mrigal and there was a loss of How many fingerings of katla,rohu and mrigal can be stored in pond .and fish can be grown properly or not. But today they are feed commercial feeds in commercial production. They reported that the developmental stages of the hybrid This ecological niche is not utilized properly. a. L. rohita     b. A maxillary pair of barbels was reported to be present. Catla are a surface feeder and sustain on phytoplankton mainly. Plate 2. Please advice. Hello,sir I am having a rearing pond having catla & mirgal in it but when I want to collect them I can catch catla but mirgal could not be collected easily pl advice me. It is easily identified by the consumers. grow-out stage the growth rate of the hybrid has been reported to vary. They can generally reach a maximum length of around 1 meter, with an average length of around 40 cm. You can stock around 100 prawns in your pond. Again, relatively better survival of the hybrid progeny was observed in the crosses between female common carp × Konda Reddy and Varghese (1983) produced this catla-rohu intergeneric hybrid and studied the embryonic and larval Average live body weight of the fish is around 1-2 kg, with a maximum length of around 12.7 kg. The observation of Alikunhi et al. However, further investigation may be necessary, especially on hybrids between Indian major carps and minor carps Hatchlings of Mrigal generally remain in the surface or sub-surface waters. Privacy Policy And the mature fish are bottom dwellers. Table 1. The pharyngeal complex in the hybrid with 144 gill rakers has shown significant deviation from both the parents In “bundh” breeding occurrence of natural hybrids may be due to congestion in the spawning ground. Thank you! Plate 7. major carps viz., hybrids produced by crossing female rohu × male catla (rohu-catla), catla female × male mrigal The catla-rohu The of both the hybrid crosses were highly viable and their growth rate was superior to their slow growing parent viz. The growth of mrigal is poorer than that of catla or rohu. Hybrids grow faster than rohu. hybrid though gained a little over mrigal in the filtering mechanism, did not gain over the mother. Regression equations for experimental diet showed that maximum linear increase was for test diet followed by reference diet (Figs.1 - 3). Plate 4. female L. fimbriatus and male C. catla (fimbriatus-catla) has been done by Basavaraju et al. Communis) which were observed to possess some useful traits from aquaculture point of So you need to pull the net deep into the water. Thank you! (1983) and Jana (1993). catla Not English Catla has no English definition. In cage of stocking both Mrigal and Grass Carp, you can follow 60:40 ratio (60 percent Mrigal and 40 percent Grass Carp fish). Most of the hatchlings were deformed with a curve in the caudal region and died You can stock same amount of Rui, Katla and Mrigal fish in your pond. Here, males might be following their like species during the chase, ultimately resulting in the All the fish size equal to 200grams per fish piece.. These Of the 13 intergeneric hybrids produced (Table 5) only four hybrids, L. rohita-C. catla, Cirrhinus mrigala-C.catla, calbasu and Labeo rohita (Chaudhuri, 1971). over 97%.
