Genetic parameters of survival for six generations in the giant freshwater prawnMacrobrachium rosenbergii

Abstract

Genetic parameters were estimated for survival of Macrobrachium rosenbergii using a fully pedigreed synthetic population formed by three introduced strains. The data included 107 398 progeny from 394 sires and 654 dams in six generations with a nested mating structure. The variance components and genetic parameters were estimated using a generalized linear mixed model with the probit link function. Available heritabilities in survival from the generation G 3 to G 5 ranged from 0.007 AE 0.020 to 0.066 AE 0.044 (P > 0.05) using a model that included the common environmental effect (c). Across generations, low heritability (0.016 AE 0.012, P > 0.05) was estimated using the model with inclusion of the c effect. There were statistically significant differences in the heritability estimates between different ponds for most generations. Moreover, the genetic correlation of survival between ponds over six generations varied from low to high (À0.0007 AE 0.17 to 0.80 AE 0.069) and was significantly different from unity. There were low correlation coefficients (À0.039 AE 0.096 to 0.342 AE 0.081) between body weight estimated breeding value (EBV) and survival EBV of families in different generations. The low heritabilities for survival are most likely caused by low genetic variation in the founder populations and reduced genetic variation because of consecutive selection.

Molecular biology of Macrobrachium rosenbergii nodavirus infection in giant freshwater prawn

“…These include the technology of RNA interference (Itsathitphaisarn, Thitamadee, Weerachatyanukul, & Sritunyalucksana, ; Jitrakorn, Chucherd, & Saksmerprome, ; Reshi, Wu, Wang, & Hong, ), recombinant DNA technology (Kumar, Karunasagar, & Karunasagar, ; Sahoo et al., ) and technology of aptamers that is also known as the synthetic antibody (Aoki & Hirono, ; Hwang et al., ; Li et al., ; Li, Zhou, et al., ; Zhou et al., ). Scanty reports of other approaches, for instances the assessment of genetic variation/inheritance in selective breeding of disease‐resistant strains (Luan et al., ) and the use of natural products of plant extracts (Farook et al., ; Khanna, Kannabiran, Babu, & Hameed, ), are available. Several critical review articles have been published in the past 10 years, revolving the general issues of biosecurity in sustainable aquaculture (Hine et al., ), in particular, infectious diseases of cultured aquatic animals (Thitamadee et al., ; Yong et al., ); and specific focuses on WTD in M. rosenbergii (Bonami & Widada, ; Hameed & Bonami, ; Na‐Nakorn & Jintasataporn, ; Pillai & Bonami, ).…”

Genetic analysis of the Pacific white shrimp (Litopenaeus vannamei): heterosis and heritability for harvest body weight

“…Genetic improvement programmes can increase the economic efficiency of farmed shrimp (Argue, Arce, Lotz & Moss ; Pérez‐Rostro & Ibarra ,b; Gitterle, Rye, Salte, Cock, Johansen, Lozano, Suárez & Gjerde ; Gitterle, Salte, Gjerde, Cock, Johansen, Salazar, Lozano & Rye ; Castillo‐Juárez, Casares, Campos‐Montes, Villela, Ortega & Montaldo ; Andriantahina, Liu & Huang ; Campos‐Montes, Montaldo, Martínez‐Ortega, Jiménez & Castillo‐Juárez ).

Genetic parameters of growth and resistance to Polydora ciliata in the pearl oyster Pinctada fucata

“…It plays an important role in selective breeding practice to estimate genetic parameters, and precise and rational estimation of genetic parameters is a premise and theory basis for making a selective breeding programme successful (Falconer & Mackay ). Estimates of genetic parameters in aquatic animals have been reported at present, mostly in fish (Ødegård, Olesen, Gjerde & Klemetsdala ; Kjoglum, Henryon & Asmundstad ; Gjerde & Saltkjelvik ; Gjerde, Ødegård & Thorland ;) and shrimps (Gitterlea, Saltec, Gjerded, Cocka, Johansenb, Salazara, Lozanoa & Ryeb ; Hung, Nguyen, Ponzoni, Hurwood & Mather ; Luan, Wang, Yang, Luo, Chen, Gao, Hu & Kong ), as well as some oysters (Langdon, Evans, Jacobson & Blouin ; Dégremont, Ernande, Bédier & Boudry ). In P. fucata , genetic parameters have been estimated for growth traits (He, Guan, Yuan & Zhang ; Deng, Fu, Du & Wang ; Wang, Deng, Du, Fu & Lu ), but not for resistance to diseases yet.…”
