Moreover, territorial males of African cichlid, Haplochromis burtoni, characterized by aggressive and reproductive activity, have significantly larger hypothalamic gonadotropin-releasing hormone (GnRH)-containing neurons and larger testes than nonterritorial males [58]. The hatchery plan; site selection and development; broodstock source and management; egg collection and incubation; and monosex fry production are highlighted. Proven Biological and Performance Information 1. Our Roots. They are nearly all private sector businesses and their success in supplying fish farms with tilapia seed has contributed to the increase in national farmed fish production. GAs act in stem growth via an enhancement of both cell division and cell elongation. This also confirms the previous results of the milt analysis for its quality parameters (Table 6). The average efficacy of sex-reversal ranges from 95 to 100 per cent depending on the intensity of management. Nile tilapia (0reochromis niloticus) accounted for 74% of the global farmed tilapia production in 2019 (FAO FIGIS, 2021). The feed additives were purchased from the local market and added directly to a mash diet, which was purchased also from the local market (contained 90.31% dry matter, 80.88 % organic matter, 23.81% crude protein, 5.47% ether extract, and 9.43% ash) after the proximate analysis according to AOAC [8] and moistened to be pelleted via a hand mincer. Since L-carnitine provides an energetic substrate for the spermatozoa in the epidydimis, contributes directly to sperm motility and may be involved in the successful maturation of the sperm. The present study was carried out during Nile tilapia hatching season of 2008 (June and July) in two phases, the first was to study the effects of three commercial feed additives on females (Therigon, Nuvisol Hatch P and Gibberllic acid) and fourth one (L - carnitine) on males brood stock, concerning their gonads characteristics and some reproductive traits. **: GSI = gonado - somatic index = gonads weight (g) 100 / fish weight (g). The strategy targets increased farmed production of 12,000 tons per year by 2030, leading to a rise in annual fish consumption to 15 kg per person, said WorldFish interim director general, Essam Yassin Mohammed. The quality of fish rearing water did not influence by the experimental treatments, and was suitable for rearing Nile tilapia brood stock according to Abdelhamid [11]. Deficiency in carnitine is associated with male infertility. L-isomer of carnitine is more effective than DL - isomer [46]. FAO Fisheries and Aquaculture Circular No. - large tilapia must be stocked initially or they will be eaten. This chapter discusses a specialized commercial tilapia hatchery technology that is described in detail in this initial part of the manual. : overcrowding, stunted growth, etc.) Table 5: Males' gonado - somatic index of brood stock Nile tilapia as affected by the dietary supplementations for 19 days feeding trial in Habas in an earthen pond (means* SE).
