“…Compared with their maternal parents, obvious differences occurred in PM and PP M hybrids in the measurable and countable data including SL/HL and CPH/CPL, indicating the distant hybridizing effect. Cluster analysis of measurable properties showed that PM , PP M had morphometric values that were closer to the maternal species than the paternal species, the maternal predominance observed in our study was similar to previous results reported in hybrids between C. catla and Labeorohita (Bhowmick, Jana, Gupta, Kowtal & Rout ). Morphological of Pc was characterized by long caudal peduncle, which is reflected by the ration of CPH/CPL 0.28, while data of Mm were 0.30.…”

Diploid and triploid hybrids of large yellow croaker (Pseudosciaena crocea, Pc) and Miiuy croaker (Miichthys miiuy, Mm) were produced by interspecific hybridization. The result showed that Pc (♀) and Mm (♂) can be successfully crossed and hybrid offspring of normal hatch rate were produced. In contrast, a lower fertilize and hatch rate were produced for hybrids of Pc (♂) and Mm (♀), and the offspring died day 19 after hatching. To confirm the ploidy of hybrid offspring, we examined the karyotypes of offspring. The result of DNA relative content investigation and genetic relationship analysis demonstrated that the major hybrid offspring were hybrid diploid. In addition, a small number of hybrid were triploid and gynogenesis diploid. Morphological analysis based on the measurable traits data indicated the success of the interspecific crosses. The natural gynogenetic diploid large yellow croaker (PP), diploid hybrids (PM) and triploid hybrids (PPM) were closer to maternal parent (Pc) than paternal parent (Mm). This study provided genetic evidences of the chromosome, DNA content and morphological levels to support the successful establishment of the polyploidy hybrids of Pc (♀) and Mm (♂).

“…However, there was a slight trend towards the hybrids being more similar to the maternal rather than the paternal species in several parameters including LCP/SL, DCP/SL, DBO/SL and ADFB‐PPFB/SL based on t ‐values from separate t ‐tests. Maternal predominance in hybrids has also been reported in hybrids between Catla catla (Hamilton) and Labeo rohita (Hamilton) (Bhowmick, Jana, Gupta, Kowtal & Rout 1981) and Poecilia shenops (Cuvier & Valenciennes) and Poecilia velifera (Regan) (George & Pandian 1997). However, in hybrids between channel catfish, Ictalurus punctatus (Rafinesque) and blue catfish Ictalurus furcatus (Lesueur), congeneric diploid hybrids were more similar to paternal rather than maternal parents (Dunham, Smitherman, Brooks, Benchakan & Chappell 1982).…”

Viable interspecific hybrids between yellowtail flounder (Pleuronectes ferrugineus, Storer) and winter flounder (Pleuronectes americanus, Walbaum) were produced by artificial insemination of yellowtail flounder eggs with winter flounder sperm. However, mean fertilization rate, hatching success and early survival up to 3 weeks post hatch were significantly lower than those of parental pure cross controls (P < 0.01). Overall, cytogenetic traits (karyological analysis and estimation of cellular DNA contents using flow cytometry) of hybrid flounder were intermediate between the two parental species. Microsatellite assay was used to distinguish the parental genomes in the hybrids; in most cases, one allele was specific to each of the parents. Morphometrics assessed by body proportions indicated that hybrids generally displayed a morphology intermediate between the maternal and paternal species. Interspecific hybrids exhibited abnormal and retarded gonad development in both sexes based on histological analysis of gonads from adult fish. The sterility of the hybrids presents a significant advantage for their use in aquaculture, as potential escapees would not be capable of reproducing in the wild and contaminating natural stocks.

“…All morphometric characters were measured to the nearest 0.1 cm with the help of pointed dividers. Measurements for 21 morphometric characters and ®ve ®n formulae were recorded for comparison between diploids and triploids as standard methods used for freshwater ®sh (Hubbs & Lagler 1947;Bonar et al 1988;Bhowmick, Jana, Gupta, Kowtal & Rout 1981 (Zar 1974). When all data met the assumptions for normality, body proportion ratios and meristic characters were compared using unpaired t-tests.…”

Triploid ®sh are usually detected by various cytological techniques, such as karyotyping,¯ow cytometry, etc. However, these methods cannot be applied on an aquaculture farm with scanty resources. In the search for an easy and rapid morphometric method, various body proportion ratios were compared between diploid and triploid ®sh. Despite many signi®cant differences of morphometric ratios among two ploidy groups, only the ratio between standard length and body depth (SL/ BD) was found to be a precise indicator of triploidy in Indian cat®sh Heteropneustes fossilis under our experimental conditions. This ratio may be useful in segregating triploids from diploids of this cat®sh in a aquaculture farm.
