“…Gómez-Márquez et al (1999) reported SL at first maturity of 22 mm in male of H. bimaculata and 27 mm in females. In this study, P. sphenops showed reproductive efficiency proportional to size, in agreement with several authors (Gómez-Márquez et al, 2016;Trujillo-Jiménez & Toledo, 2007). Sexual maturity is a function of size, and may be influenced by age, as well as abundance and availability of food, water temperature and day length (Nikolsky, 1978).…”

“…A higher proportion of females favors reproductive success, spread, and successful invasion. The GSI values indicated that P. sphenops and P. bimaculatus are iteroparous, which permits population increase and indicates effective exploitation of environmental resources, which is similar to those reported byGómez-Márquez et al (2016).…”

“…Male growth ceases when gonopodium are fully formed, and males do not live long after reaching sexual maturity (Snelson, 1984). Some studies suggest that the males are precocious compared to females (Gómez-Márquez et al, 2016;Ponce de León, Rodríguez, & León, 2013). The males reached first maturity at a smaller size than females.…”

“…It has been introduced into several ecosystems in Mexico, including the Teuchitlán River (TR) in Jalisco State, where its diet comprises mainly organic detritus (Trujillo-Jiménez & Toledo, 2007). Spawning occurs during the rainy season in artificial systems in Morelos State Gómez-Márquez, Peña-Mendoza, & Guzmán-Santiago, 2016).…”

SummaryReproductive biology of invasive species is not often studied relative to the invasion process, although it may provide an accurate indicator of the invasion stage. We evaluated the reproductive biology of the exotic fish species Pseudoxiphophorus bimaculatus and Poecilia sphenops in the Teuchitlán River, Jalisco, Mexico by fertility, size at first maturity, sex ratio, gonad maturity stage, gonadosomatic index, condition factor, size-structure, and habitat. The reproductive variables were related to environmental characteristics using the non-metric analysis of multidimensional scaling. A total of 1374 specimens of P. bimaculatus and 571 of P. sphenops were captured by seine netting and electrofishing. Maximum fertility of P. bimaculatus was 15.99 ± 2.27 embryonated eggs and embryos and, for P. sphenops, 31.26 ± 4.17. Females predominated among P. bimaculatus, while in P. sphenops the sex ratio was ~1:1. We found mature female and male of P. bimaculatus in degraded sites and juveniles in the springs. Poecilia sphenops reproduced along the river. The establishment of both invasive species in the Teuchitlán River is evidence that they share the reproductive habitat with native fish species, and tend to spread and colonize new areas.

“…The males of P. mexicana showed negative growth, except in the sub-optimal condition, which suggests that body parts do not grow at a similar rate, and thus fish grow in length more than in weight. Similar results have been found in other species, such as Poecilia sphenops (Martínez-Trujillo, 1983;Gómez-Márquez et al, 2016;Ramírez-García et al, 2018), P. gracilis (Contreras-MacBeath & Ramírez-Espinoza, 1996;Gómez-Márquez et al, 2008), and Pseudoxhiphorus bimaculatus (Ramírez-García et al, 2018). However, Contreras-MacBeath & Ramírez-Espinoza (1996) reported isometric growth for P. gracilis.…”

Despite the increase of exotic species in bodies of water, studies on the population structure of coexisting native and exotic fish species are rare. We evaluated the population structure of the native Poecilia mexicana and non-native Poeciliopsis gracilis species in an environmental gradient and its relation to the habitat characteristics in the Jalpan River, located in the state of Queretaro, Mexico. We calculated size structure, sex ratio, gonad stage, and condition factor for both species. Visual-based habitat quality, riparian quality, and physical and chemical characteristics of water were also evaluated. A total of 322 individuals of P. gracilis and 762 of P. mexicana were captured with different fishing nets due to the habitat heterogeneity. Study sites were classified into three categories of habitat conditions: poor, marginal, and sub-optimal. P. mexicana females showed a complete structure of sizes in the poor habitat category. P. gracilis did not show a complete structure in any habitat category. The sub-optimal category of habitat conditions had the lowest number of specimens for both species. Poor category showed a sex ratio of 1:1 (females: males) for P. mexicana while in P. gracilis, females were more abundant than males (sex ratio 5:1). Fulton's factor was higher for P. mexicana than for P. gracilis. Our results showed that habitat quality of the river affected size structure, stages of development, and sex ratio of the two species, but did not show conclusive evidence of favored species or reproductive competition.

The objective of this research is to enhance the growth and reproductive performance in the test fish, red eyed orange molly (Poecilia sphenops) exposed to standardized manipulated photoperiod. In present study, growth and gonadal development of the test fish with an average initial weight (0.52g) and an average total length (3.2cm) exposed to two photoperiods (18L:6D and 10L:14D) at constant light intensity (1500 lx) for a period of 60 days was investigated. The fish were fed with formulated feed twice a day as per 10% of body weight. During a long day photoperiod (18L:6D) significant increase in growth parameters such as, weight gain (2.2 ± 0.04), feed conversion ratio (8.9 ± 0.004) and specific growth rate (1.2 ± 0% day -1 ) was observed. Mean gonadosomatic index (GSI) in female (30.4 ± 0.11) and male fish (2.0 ± 0.17) was also significantly higher in long-day photoperiod followed by short day photoperiod (10L:14D). The results confirm that manipulated long-day photoperiod induced somatic growth and enhanced gonadal development in P. sphenops without causing any stress.All rights reserved.
