Protein contain is a cornerstone mechanism and form part and parcel of nutritive value in particular rely on season, food intake, breeding and spawning capacity. The protein contain in the fish body constitute as a firsthand source of energy for physiological functions incorporating reproduction. Present investigation display that variations in the protein is observed from the mature fishes of Indian major carps such as Cyprinus carpio comprises 20 to 50cm selected for the estimation of protein study considered as experimental and control fishes upon administration of PGE, ovaprim and ovatide synthetic hormonal doses to the male and female sex ratio separately. Protein in the liver of female major carps may be because of vitellogenin, a lipoprotein which is synthesized in the liver and is transported to the ovary (Wallace, 1985). Moreover, gonadal protein enhanced with maturation amongst these fishes. Protein estimation represents the variations throughout the study period amongst the muscle, gonad and liver. After hormonal injections are given then fishes are kept in the breeding pool at the Fish Seed Production Centres (FSPC) located near Paithan barrage. The protein is estimated upon satisfactory administration of hormonal doses Pituitary Gland Extract and by other two synthetic hormonal doses viz. Ovaprim and Ovatide. Study is conducted during 2013 to 2014.

An adaptive trial was undertaken for early breeding of carps in four private hatcheries of Khordha district in the state of Odisha, India. CIFABROODTM, a promising carp brood diet was used to observe the breeding performance and seed production of carps in early monsoon. CIFABROODTM was provided in experimental ponds while farm made feed prepared by the hatchery owners were used in the control ponds. After 45days of feeding, fishes in the trial ponds became mature while in the control ponds fishes were immature. Average fertilization rate was observed to be 88.14% with an average spawn recovery of 2.14 lakh spawn/kg body weight of female. Highest average fertilization rate was found in mrigal followed by rohu and catla. Similarly average spawn recovery per kg of female body weight indicates a highest recovery in rohu followed by mrigal and catla. In turn the spawn buyers had an average survival rate of 42.18% from spawn to fry and 73.5% from fry to fingerling rearing. This adaptive trial has reconfirmed CIFABROODTM as a proven carp brood diet which has shown to impact at all the three crucial stages of seed production. The positive outcomes of the attributes of innovation were highly towards an increased rate of adoption.

Abstract Genetic and non-genetic aspects of seed quality are discussed. A system of seed production for Indian major carps and Chinese carps, which require sophisticated hatchery facilities, has been established in the country. However, there is concern about deterioration of the quality of broodstock in current hatchery management. Self-recruiting species like tilapia, common carp and silver barb can be bred in decentralized systems but the absence of a regular supply of quality broodstock may lead to poor seed quality due to poor farm management at homestead level.

The effects of different ova diameters on hatching, growth and survival of fry of the common carp (Cyprinus carpio var. communis, Cyprinidae) and Indian major carps viz.Catla catla, Labeo rohita, Cirrhinus mrigala (Cyprinidae) were examined. The four female brooders of different weight and size of each of Cyprinus carpio var. communis, Catla catla; Labeo rohita and Cirrhinus mrigala were collected. The highest mean ova diameter was observed in (Cyc 4) 1.235 ± 0.006 mm, (Cc 4) 5.386 ± 0.098 mm, (Lr 4) 4.94 ± 0.167 mm and (Cm 4) 4.95 ± 0.091 mm; highest fertilization rate (Cyc 4) 92.48%, (Cc 4) 85.42%, (Lr 4) 89.64%, (Cm 4) 86.49%; highest hatching percentage (Cyc 4) 82.32%, (Cc 4) 79.67%, (Lr 4) 81.28%, (Cm 4) 80.17% and highest survival (Cyc 4) 75.57%, (Cc 4) 76.36%, (Lr 4) 80.51%, (Cm 4) 68.35% respectively. The specific growth rate was also found highest in Cyprinus carpio var. communis (Cyc 4) 5.94%, Catla catla (Cc 4) 5.62%, Labeo rohita (Lr 4) 5.81% and Cirrhinus mrigala (Cm 4) 5.86% in fry of brooders having maximum weight. The direct relationship of ova diameter to fertilization rate, hatching, survival percentage and the specific growth rate of Cyprinus carpio var. communis, Catla catla, Labeo rohita and Cirrhinus mrigala were recorded. However, after the fifth week, the growth rate of spawn reduced in all the groups and was least at the end of the eighth week.

AbstractThe present study investigated possible effects of dietary malic acid on the expression of immunity, antioxidant and growth related genes expression as well as skin mucus immune parameters in common carp. Common carp (Cyprinus carpio) fingerlings were fed diets supplemented with different levels (0 [control], 0.5%, 1%, 2%) of malic acid (MA) for 60 days. The results revealed highest expression levels of immune-related genes (tnf-alpha, il1b, il8 and lyz) in skin of common carp fed 2% MA (P < 0.05). Regarding 1% MA treatment comparison with control group, significant difference was noticed just in case of lyz (P < 0.05). Evaluation of growth related genes expression revealed no significant difference between treatments (P > 0.05). The study of antioxidant related genes (gsta and gpx) in common carp skin fed with MA, showed significant difference between treated groups and control (P < 0.05). Carps fed with 2% MA had highest alkaline phosphatase activity in skin mucus compared other treated groups and control (P < 0.05). There were no significant difference between 0.5% and 1% and control (P > 0.05). The study of total protein and total immunoglobulin (Ig) in common carp skin musus revealed no alteration following MA treatment (P > 0.05). The present data demonstrated that feeding with MA altered immune and antioxidant genes expression in skin mucus of common carp.

Signaling Components

Control of cellular function is extremely complex, being reliant on a wide range of components. Several of these are small oxygen-based molecules. Although reactive compounds containing oxygen are usually harmful to cells when accumulated to relatively high concentrations, they are also instrumental in the control of the activity of a myriad of proteins, and control both the upregulation and downregulation of gene expression. The formation of one oxygen-based molecule, such as the superoxide anion, can lead to a cascade of downstream generation of others, such as hydrogen peroxide (H2O2) and the hydroxyl radical (∙OH), each with their own reactivity and effect. Nitrogen-based signaling molecules also contain oxygen, and include nitric oxide (NO) and peroxynitrite, both instrumental among the suite of cell signaling components. These molecules do not act alone, but form part of a complex interplay of reactions, including with several sulfur-based compounds, such as glutathione and hydrogen sulfide (H2S). Overaccumulation of oxygen-based reactive compounds may alter the redox status of the cell and lead to programmed cell death, in processes referred to as oxidative stress, or nitrosative stress (for nitrogen-based molecules). Here, an overview of the main oxygen-based molecules involved, and the ramifications of their production, is given.

Experiments were conducted for the study of nutrient budget in farmers' ponds (0.4–0.6 ha) in Orissa, India, at stocking densities of 0.30–0.38/m2 for scampi (Macrobrachium rosenbergii) and 0.60–0.70/m2 for Indian major carps (Catla catla, Labeo rohita and Cirrhinus mrigala). The average initial body weights of scampi and the major carps were 0.02 and 8–10 g, respectively. The culture period was 272–292 days. Feed was the main input. The FCR (feed conversion ratio) varied from 1.78 to 1.83. Feed and cow dung were applied to these ponds as organic inputs. At harvest time, the average weight of scampi and carps varied from 73 to 92 g and from 718 to 820 g, respectively. Among all the inputs, feed alone accounted for 97.60% total nitrogen (N), 97.90% total phosphorus (P) and 94.72% total organic carbon (OC), respectively. The harvest of scampi and carps accounted for recovery of 52.45% N, 19.43% P and 18.12% OC, respectively. N, P and OC accumulated in sediment were 38.31, 71.40 and 69.50%, respectively. The median nutrient loads in the fish pond effluents were equivalent to 0.58 kg of inorganic N, 0.135 kg of P and 8.83 kg of total OC per ton of Indian major carps and scampi production.
