Fenneropenaeus chinensis is confined to the Yellow Sea and Bohai Sea in China and the West Coast of the Korean Peninsula. Intra-and intercross populations were produced between Rushany (YP) and Korean (KN) populations. Seven traits were recorded. The heterosis of hybrids was computed and comparison between treatments was performed by ANOVA. At the fourth month after post-larvae, six indexes of growth trait and viability showed a range of heterosis, ranging from 0.514% to 14.950%. At the fifth month after post-larvae, six indexes of growth trait and viability ranged from -9.000% to 19.090%. The negative heterosis was observed in CL, HST and viability. The heterosis of KN♀×YP♂ tended generally to increase as the age of the Chinese shrimp increased while the heterosis of YP♀×KN♂ tended to decrease. The results indicated that the viability of reciprocal hybrids were not significantly different (P>0.05) from their parents during the experiment. The result of ANOVA indicated that the F1 hybrids were significantly different (P<0.05) in WST and TW at the fourth month. The multiple comparisons of LSD test indicated that the hybrids of YP♀×KN♂ were significantly different (P<0.05) from their parents in TW. The hybrids of YP♀×KN♂ were significantly different (P<0.05) from the other three combinations in WST. At the fifth months, the F1 hybrids had significant difference (P<0.05) in body weight while other traits showed no significant differences (P>0.05) from their parents. The multiple comparisons of LSD test indicated that the hybrids of KN♀×YP♂ were significantly different (P<0.05) from the KN parents in TW. The results indicate that in experimental conditions, the F 1 hybrids created from two populations of Chinese shrimp showed a certain level of heterosis for growth performance and viability. The crossing scheme may improve growth performance and viability in Chinese shrimp, but the improvement may be limited because effective crossbreeding requires the maintenance of pure, preferably inbred, lines and possibly involves specialized sire and dam lines. Therefore, the exploitation of heterosis through single crossbreeding in Chinese shrimp is of limited utility in practical commercial shrimp aquaculture in spite of the potential of significant heterosis. The crossbreeding of different populations can be applied in the establishment of base populations.

“…Though slow-growing, this medium sized carp is in good demand due to high market value, excellent flavour and meat quality (Basavaraju et al, 1995). Cyprinus carpio Linnaeus, 1758, the common carp, accounts for the world's second highest farmed fish production in Asia (Milstein, 1992).…”

This study was conducted in indoor, aerated plastic tubs to estimate the digestibility of dry matter and nutrients by the carps, Labeo fimbriatus (Bloch, 1795) and Cyprinus carpio Linnaeus, 1758, from three feed ingredients viz., azolla, soybean meal and silkworm pupa incorporated at levels ranging from 0-40% in a diet comprising equal amounts of rice bran and groundnut oil cake using crude fibre as the marker. Activity of the major digestive enzymes was also estimated in the gut of fish at the end of the experimental trial. Utilisation of azolla protein was comparable with that of control diet up to 20% incorporation in both L. fimbriatus and common carp. Major nutrients from soybean were better utilised up to 40% incorporation by the two species. Protein digestibility from silkworm pupae increased at 20% incorporation and decreased at 40% in L. fimbriatus, while fat and nitrogen-free extract digestibility was higher at 20-40% incorporation. In common carp, higher digestibility of protein and fat was recorded at 10-30% inclusion levels of silkworm pupa.

“…Through the interaction between mother and siblings, the early growth and survival traits of hybrid individuals are affected to some extent. Scholars ordinarily observe differences from hybridization in fish research (Bartley et al, ; Basavaraju, Devaraj, & Ayyar, ). During hybridization for populations of the genus Echinometra (Rahman, Uehara, & Lawrence, ; Rahman, Uehara, & Pearse, ), Argopecten circularis (Cruz & Ibarra, ) and Crassostrea virginica (Mallet & Haley, ), the growth and survival of hybrid offspring in the larval stage had significant maternal effects that disappeared with individual growth (Roff & Sokolovska, ).…”

The paper reports a study focused on breeding new rapidly growing and heat‐tolerant strains in a commercially important Asian bivalve, Sinonovacula constricta. To breed a new strain of S. constricta with fast growth and high temperature tolerance, complete diallel crosses were carried out using three different geographical culture populations from Zhejiang (Z), Fujian (F) and Guangdong (G) provinces, China. Larval and spat growth and the survival and heat tolerance of spats were compared in detail. The experimental serial growth traits extracted from larval and spat measurements (shell length and shell height) indicated that there was no difference between six hybrid crosses and parental crosses at the larval stage; while at the spat stage, some differences were observed. The hybrid crosses ZF (Z♀ × F♂), ZG (Z♀ × G♂) and FG (F♀ × G♂) outperformed the parental groups in shell length at the end of intermediate culture, with lengths of 21.77 ± 0.28 mm, 21.55 ± 0.29 mm and 21.44 ± 0.20 mm respectively. For spat survival rate, the hybrid cross ZF (Z♀ × F♂) had a significantly larger value (88.89 ± 4.16%) than all the other groups, and the hybrid cross ZG (Z♀ × G♂) had a significantly larger rate than the cross GZ (G♀ × Z♂) and parental crosses ZZ (Z♀ × Z♂) and GG (G♀ × G♂). The hybrid crosses ZF (Z♀ × F♂), ZG (Z♀ × G♂) and FG (F♀ × G♂) exceeded the parental groups in heat tolerance, but there was no significant difference. The growth, survival and heat tolerance results showed that the crosses ZF, ZG and FG in this study were the best hybridization combinations for genetic improvement, which could have significant implications for the development of razor clam aquaculture. This work provides a theoretical basis for breeding new varieties (strains) that grow rapidly and are heat tolerant.
