Effect of dietary supplementation of fatty acids and vitamins on the breeding performance of the carp Catla catla

Abstract

-Five isonitrogenous diets (∼33% crude protein) were fed to the brood female carp, Catla catla (weighing 3.0 to 5.5 kg), for a period of 93 days in order to observe their breeding performance in earthen ponds. Diet-I (control) contained only basic ingredients like rice bran, groundnut oil cake, roasted soybean meal, fish meal and mineral mixture; diet-II contained added vitamins; diet-III contained added vitamins and vegetable oil (rich in n-6 polyunsaturated fatty acids, PUFA); diet-IV contained added vitamins and fish oil (rich in n-3 PUFA); and diet-V contained added vitamins and a mixture of vegetable and fish oils. The results showed that nutritional quality of the diet considerably influenced breeding performance in the species. The total number of matured females was the highest in the diet-V group and maturity was advanced by 35 days in this group compared to the control. In diet-III and diet-V groups, all the maturated females bred fully and the relative fecundity was increased significantly in diet III, IV and V. The maximum (73.4%) fertilisation rate was observed in the diet-V group, followed by 61.3%, 56.8%, 49% and 22.7% in diet-I, diet-IV, diet-III and diet-II groups respectively. Most of the eggs in the diet-II treatment group remained immature. The various data thus obtained suggest that dietary supplementation of both n-3 and n-6 PUFA, is essential to improve gonadal maturation, breeding performance and spawn recovery in the Catla female broodstock. diet / fatty acid / broodstock / breeding performance / Catla Reprod.

Effect of lipid feeding regimes and conditioning periods on gonads fatty acid profile and reproductive performance of the Nile tilapia (Oreochromis niloticus) broodstock

“…Same trend was observed after four weeks period. SBO-based diet revealed same trend in findings of Santiago and Reyes (1993) and Nandi et al (2001). Concerning linolenic acid (ALA), female broods delivered FO source in their diet in different forms (FO cont.…”

“…Tilapia broods fed mixture of palm oil+fish oil(9:1) diets showed better reproductive performance than those fed palm oil-based diet (Hajizadeh et al, 2008). Furthermore, Nandi et al (2001) observed that the broodstock females carp Catla catla fed mixture diet (SBO+FO 9:1) had the highest fully matured females and relative fecundity followed by fish fed SBO diet without significant differences, while broods fed FO diet showed the lowest reproductive performance. The same were confirmed by the results reported in Table 8, where tilapia broodstock that fed MIX diets in forms (MIX cont.…”

“…or SBO am /FO pm ) showed generally the best reproductive performance followed by fish fed SBO diet without any significant differences. Based on these results it could be suggested that despite the importance of n-6 fatty acid family for tropical fish like tilapia (Teshima et al, 1982;Lovell, 1989;NRC, 1993;Popma and Masser, 1999;Shiau, 2002), it seems that broodstock may also need lesser quantities of n-3 fatty acid family (Santiago and Reyes, 1993;Nandi et al, 2001;Hajizadeh et al, 2008) to obtain the best reproductive performance. Otherwise, El-Sayed et al (2005) stated that no significant differences for reproductive performance among fish fed FO, SBO or MIX diets for 165 days under condition of 0% salinity.…”

On-farm evaluation of formulated feeds on the breeding performance of Catla catla reared in rural ponds

“…But the breeding success and seed production of this species is comparatively low because of several factors, including gonadal fat accumulation, improper gonadal maturation and partial spawning (Chaudhuri & Alikunhi 1957; Chaudhuri 1960; Badami & David 1964; Bhowmik et al 1978). Our earlier study (Nandi et al 2001) reveals that this occurs occasionally in spite of taking intensive care of recommended management measures. Izquierdo et al (2001) pointed out that the important limiting factor for the successful mass production of seed of many cultured fish species is due to the unpredictable and variable reproductive performance.…”

Effect of plant and animal protein sources on the growth, gonadal maturity and proximate composition of Labeo rohita (Hamilton, 1822)

“…Brood stock nutrition of carps is one of the most poorly researched areas in aquaculture. So far few studies have been made on brood stock nutrition of carps (Singh and Dhawan 1996;Khan et al, 2003Khan et al, , 2005Anonymous 2006;Nandi et al, 2001Nandi et al, , 2007. To a large extent, this may be due to the necessity of suitable indoor or outdoor culture facilities for maintaining large groups of adult fish and the consequent higher cost of running and conducting extended brood stock feeding trials (Varghese et al, 2009).…”
