Abstract

The red cherry shrimp RCS Neocaridina davidi is a tiny shrimp that has a bright red color; therefore, it has become a popular ornamental species. The aims of this study are to determine the fecundity, egg size, and maturation time of the RCS at different sizes and also to determine its ovarian maturity criteria. A total of 18 adult female shrimps in 3 different size groups based on carapace length were used. They were grouped as small S: 1.5-1.7 cm , medium M: 1.8-2.0 cm , and large L: 2.1-2.3 cm ; a total of 36 adult male shrimps 1.5 ± 0.2 cm were used in the research. The parameters observed in this study were fecundity, size of the egg diameter , and gonadal maturity of the female. The L-size group of the RCS obtained the highest fecundity, the highest uniformity of egg size, and the fastest maturation period, so it can be concluded that the best reproductive performance was observed in the L-size group of RCS. We also determined 4 ovarian maturity criteria of the RCS so that they can be used for production efficiency, in further research, and for its culture.

观赏红樱桃虾(Neocaridina davidi)的一些繁殖力参数和卵巢成熟标准

红樱桃虾(RCS Neocaridina davidi)是一种小虾，颜色鲜红;因此，它已成为一种流行的观赏树种。本研究的目的是确定不同大小的RCS的繁殖力、卵大小和成熟时间，并确定其卵巢成熟标准。试验选用18只雌虾，按甲壳长度分为3个不同大小组。小S: 1.5 ~ 1.7 cm，中M: 1.8 ~ 2.0 cm，大L: 2.1 ~ 2.3 cm;研究对象为身高1.5±0.2 cm的成年雄性对虾36只。本研究中观察到的参数是生殖力、卵径大小和雌性性腺成熟度。RCS的L-size组繁殖力最高，卵大小均匀性最高，成熟期最快，因此，RCS的L-size组的繁殖性能最好。我们还确定了RCS的4个卵巢成熟度标准，以便它们可以用于生产效率，进一步的研究和培养。

期刊介绍： The Turkish Journal of Veterinary and Animal Sciences is published electronically 6 times a year by the Scientific and Technological Research Council of Turkey (TÜBİTAK). Accepts English-language manuscripts on all aspects of veterinary medicine and animal sciences. Contribution is open to researchers of all nationalities. Original research articles, review articles, short communications, case reports, and letters to the editor are welcome. Manuscripts related to economically important large and small farm animals, poultry, equine species, aquatic species, and bees, as well as companion animals such as dogs, cats, and cage birds, are particularly welcome. Contributions related to laboratory animals are only accepted for publication with the understanding that the subject is crucial for veterinary medicine and animal science. Manuscripts written on the subjects of basic sciences and clinical sciences related to veterinary medicine, nutrition, and nutritional diseases, as well as the breeding and husbandry of the above-mentioned animals and the hygiene and technology of food of animal origin, have priority for publication in the journal. A manuscript suggesting that animals have been subjected to adverse, stressful, or harsh conditions or treatment will not be processed for publication unless it has been approved by an institutional animal care committee or the equivalent thereof. The editor and the peer reviewers reserve the right to reject papers on ethical grounds when, in their opinion, the severity of experimental procedures to which animals are subjected is not justified by the scientific value or originality of the information being sought by the author(s).
