“…The magnitude of difference in IGF-1 levels of carps and other fish species was in the order of 2-200. Available evidence suggested that serum IGF-1 levels in teleosts positively correlate with growth rates of individuals and could be used to evaluate the growth performance for aquaculture and stock assessment (Silverstein et al, 2000;Beckman et al, 2004a;Dyer et al, 2004;Li et al, 2004;Picha et al, 2009;2012). The results on serum IGF-1 levels of IMCs also provide supportive evidence to the above earlier reports on several other species as indicator of fish growth.…”

“…The number of insulin and IGF receptors in fish is regulated by the nutritional status so that it can be altered according to the physiological need (Planas et al, 2000). Reports are available on the levels of serum IGF-1 in different fish species such as chinook salmon Oncorhynchus tshawytscha (Beckman et al, 2004a;b), coho salmon O. kisutch (Pierce et al, 2004;Beckman et al, 2004a;b), Atlantic salmon Salmo salar (Dyer et al, 2004;Shimizu et al, 2006), tilapia Oreochromis mossambicus (Uchida et al, 2003), gilthead seabream Sparus aurata (Pé rez-Sá nchez et al, 1995;Mingarro et al, 2002;Gómez-Requeni et al, 2004;2005), channel catfish Ictalurus punctatus (Silverstein et al, 2000;Li et al, 2004) and Atlantic cod Gadus morhua (Davie et al, 2007).

The insulin-like growth factor-1 (IGF-1) plays an important role in the regulation of development and growth of fish.Aquaculture researchers consider it as a potential growth rate indicator. Reports on the IGF-1 of carps are limited. This study was undertaken to determine the serum IGF-1 levels of Indian major carps (IMCs) cultured in the normal pond, sewage-fed pond and captive conditions. Labeo rohita of the normal pond recorded the highest serum IGF-1 level (2.10±0.14 ng/ml), followed by Catla catla (1.99±0.17 ng/ml) and Cirrhinus mrigala (1.82±0.12 ng/ml). Captive held C. catla recorded the highest serum IGF-1 (2.10±0.19 ng/ml) compared to L. rohita (2.04±0.08 ng/ml) and C. mrigala (1.90±0.09 ng/ml). In the sewage-fed pond, C. catla, L. rohita and C. mrigala recorded the serum IGF-1 levels of 2.38±0.36 ng/ml, 2.06 ±0.03 ng/ml and 1.07±0.06 ng/ml, respectively. Significant differences existed among the serum IGF-1 levels of C. mrigala reared in the normal and sewage-fed pond as well as the captive and sewage-fed pond (P < 0.05). It appears from the results that C. catla and L. rohita are the ideal cultivable species under the sewage-fed aquaculture. The serum IGF-1 level may be an effective indicator of the differences in growth of carps.

Abstract.-A 9-week growth study was conducted to compare the fingerling performance of two genetic groups of channel catfish Ictalurus punctatus (U.S. Department of Agriculture [USDA] 103 and USDA303) with that of blue catfish I. furcatus and their hybrid in an aquarium rack system. Fish of approximately 20 g were randomly selected from multifamily populations and acclimated to the aquarium rack system for 2 weeks prior to the start of the 9-week study. Differences in growth indices, feed and protein efficiency, nitrogen retention, whole-body proximate composition, and plasma cortisol levels were determined at the completion of the study. The USDA303 channel catfish gained significantly more weight and consumed more feed than each of the other genetic groups. Feed and protein efficiency were similar among USDA103, USDA303, and hybrid catfish but were lower for blue catfish. Nitrogen retention was highest for hybrid catfish and lowest for blue catfish. No differences in final body composition were observed between genetic groups when final weight was used as a covariate. Plasma cortisol levels after 9 weeks ranged from 9.7 ng/mL in blue catfish to 24.5 ng/mL in USDA103 channel catfish but were not significantly different among genetic groups. This study demonstrates improved growth of the USDA303 channel catfish after two generations of selection for increased body weight and reports significant differences in performance among channel catfish, blue catfish, and hybrid catfish in an aquarium rack system.The majority of catfish grown and sold in the United States for human consumption are channel catfish Ictalurus punctatus. In the early 1990s, interest in another ictalurid, the blue catfish I. furcatus, as a potential culture species prompted several studies to compare culture characteristics of the blue catfish to those of the channel catfish (Dunham et al. 1990(Dunham et al. , 1993Tidwell and Mims 1990). More recently, a slow economy and the threat of foreign fish imports to the profitability of U.S. catfish farming have prompted further interest in the blue catfish as well as renewed efforts in genetic improvement of channel catfish and hybridization between channel catfish and blue catfish. Several studies comparing the performance of channel catfish, blue catfish, and their hybrid in ponds have been published (Dunham et al. 1990(Dunham et al. , 1993Tidwell and Mims 1990;Argue et al. 2003;Bosworth et al. 2004;Li et al. 2004). However, little has been published regarding the impact of genotype-environment interactions on performance evaluations. Efficient performance evaluations of large numbers of catfish strains or families require very large pond or tank facilities with good environmental control. Often, the constraints of space and environmental control dictate the use of aquaria for large comparative studies of juvenile performance. The choice of culture system may, however, skew the results of the comparison. In one study, Dunham et al. (1990) found that hybrid catfish grew faster than channel catfish i...

A pond production trial was conducted to evaluate the economics of raising Channel Catfish Ictalurus punctatus in intensively aerated ponds operated under the single‐batch cropping system. Channel Catfish fingerlings averaging 0.09 lb were stocked at 6,000, 8,000, 10,000, and 12,000 fish/acre with six replicate ponds (1 acre) per treatment. A treatment of hybrid catfish (♀ Channel Catfish × ♂ Blue Catfish I. furcatus) fingerlings stocked into five replicate ponds at 12,000 fish/acre was concurrently evaluated to compare the economic performance of hybrids and that of Channel Catfish. All ponds were provided with a fixed‐paddlewheel aerator (10 hp/acre) and were fed once daily to apparent satiation for 206 d. For Channel Catfish, the gross yield ranged from 6,562 to 9,039 lb/acre, showing nominally linear trends of increasing yield with stocking density. However, the same trend was not seen in the relationship between costs and stocking density: the highest breakeven price (US$1.07/lb) was associated with the lowest density treatment (6,000 fish/acre), and the least cost ($0.96/lb) was associated with the intermediate density of 8,000 fish/acre. Average annual net cash flows from all Channel Catfish treatments were insufficient to make the investment in intensive aeration profitable in the long run (10 years). The hybrid catfish treatment (12,000 fish/acre) outperformed all Channel Catfish treatments in terms of yield (17,542 lb/acre), which offset some of the fixed costs associated with intensively aerated ponds and resulted in a lower cost of production ($0.85/lb) and better long‐term returns (17%). This study indicated that Channel Catfish do not perform well—either biologically or economically—at densities greater than 8,000 fish/acre in single‐batch, intensively aerated ponds. The study reflects current industry trends, where integrated farms (farms with their own processing plants) with yield‐maximizing business objectives prefer raising hybrid catfish in single‐batch systems, while nonintegrated farms prefer raising Channel Catfish in multiple‐batch systems.
