“…Although triploidy induction has been considered as one of methods for reproductive containment of transgenic fish, an important shortfall of triploidy is the occurrence of fertility in triploid fish (Pandian and Koteeswaran, 1998;Arai, 2001;Lee and Donaldson, 2001;Nam et al, 2001b). Many previous studies reported the possibility that triploid males might produce limited but potentially functional sperm (Kim et al, 1994;Van Eenennam et al, 1990), and, furthermore, in some cases, older triploids were found to be partly fertile even in females (Lee and Donaldson, 2001).…”

Generation of valuable transgenic fish with desirable phenotypes has potential implications for food production as well as many other bio-industries. Transgenic engineering of fish genome would provide a quantum leap over traditional selection and breeding methods by offering the powerful means to increase the efficiency of farming practices with desired traits. With this purpose, research with a wide spectrum of success has been in progress for the past two decades to generate valuable transgenic fish strains. Transgenic manipulations have already made an important contribution in all disciplines fisheries sciences and aquaculture, however, commercial application of transgenic fish strains is still complicated by many scientific and social issues. Here this mini-review introduces briefly the historical background, principle, current status and perspective of transgenic manipulation in fish.

“…The growth performance of single-sex and mixed-sex populations has been compared for many cultured aquatic species (Goudie et al 1994;Pongthana et al 1999;Sheehan et al 1999;Triño et al 1999;Dan and Little 2000;Lawrence et al 2000;Nam et al 2001). In Nile tilapia, Oreochromis niloticus L., the biomass of monosex fish at harvest was 30-50% higher than that in mixed culture (Mair et al 1995).…”

The silver perch, Bidyanus bidyanus (Mitchell 1838), displays sexual dimorphism in size, with females reaching larger maximum size than males. In an attempt to produce all‐female populations, larvae at 30 d posthatching were fed an estradiol‐17β (E2) diet at dosages of 0, 60, and 120 mg/kg for 30 d. Histological examination of gonads revealed that all E2‐supplemented diets resulted in significantly higher (P < 0.05) feminization rates (97.22–100%) than did the control (39.69%) but with no difference between the two E2 diets (P > 0.05). Female and male gonads were observed in fish fed the 60 mg E2/kg diet. No significant differences were observed in the survival rate, weight gain, gonad weight and length, specific growth rate (SGR), or gonadosomatic indexes, except for gonad length and SGR at the end of the experiment. Although the ovary length of fish fed the 60 mg E2/kg diet was significantly shorter than that of the control groups, no abnormalities were detected. In contrast, fish fed 120 mg E2/kg grew faster than the other fish and showed sexual dimorphism. Our results suggest that supplementation of E2 at 60–120 mg/kg diet could be applied to establish all‐female populations of silver perch.

“…Artificial gynogenesis involves induction of haploid development by insemination with genetically inactivated sperm and diploidization of the female chromosome complement in order to produce viable diploid gynogenetic offspring. Several reports have described the techniques to induce meiotic gynogenesis in Siluriformes, for example, in Clarias gariepinus (Volckaert et al, '94, '97;Váradi et al, '99;Galbusera et al, 2000) and Silurus asotus (Nam et al, 2001). The main rationale for use of this technique in culture of these fish was the production of monosex population (Nam et al, 2001).…”

Artificial gynogenesis in S. glanis has been successfully induced by Krasznai and Márián ('87) with a relatively high (20-30%) survival rate of gynogenotes.…”

Induction of diploid gynogenesis in Wels catfish (Silurus glanis) using UV‐irradiated grass carp (Ctenopharyngodon idella) sperm

This article describes the first successful induction of meiotic gynogenesis in Wels catfish (Silurus glanis) using heterologous sperm of grass carp (Ctenopharyngodon idella) with DNA inactivated by means of UV-irradiation at 4800 J/m(2). The cold shock at 6 degrees C (duration of 20 min) started in the nineth minute after fertilization was found as efficient in retaining the second polar body and producing meiotic diploids. Successful induction of meiotic gynogenesis was confirmed by the microsatellite DNA analysis, which revealed only maternal inheritance in gynogenetic offspring. Ploidy of gynogenetic offspring was verified by the application of active nucleoli counting analysis.
