“…They concluded that the sausage with the least amount of fish meat (a ratio of 10:60, fish meat:beef) showed the best bromatological parameters. Regarding the nutritional value of the meat of D. latifrons, López-Huerta et al (2018) determined the proximal composition and the fatty acid profile of wild and cultivated specimens of D. latifrons, intending to assess the effect of feeding cultured fish with a commercial diet for tilapia (Oreochromis spp.). The protein content of the muscle of wild fish was higher than that of farmed fish, but total lipid content was lower.…”

The present work is a review of the literature on the native Mexican fish Dormitator latifrons. The aim is to contribute to the integration and systematization of current knowledge to make it easier to identify existing knowledge gaps and breakthroghs Moreover, promote the successful cultivation and protection of this species whose consumption is increasing in Latin America. A review of the articles related to D. latifrons published in international and regional databases was carried out. The articles reviewed focus on taxonomy and systematics, phylogenetic, geographic distribution, ecology, physiology, reproduction, development, pathology, health, and the technologies used to cultivate this fish species. The conclusion is that, even though the cultivation of D. latifrons is of commercial interest in some countries, there are still significant gaps in our knowledge of biology and, consequently, the domestication potential of the species. Filling these gaps will require systematic research efforts on protecting natural populations and improving mass cultivation techniques.

“…(Arriaga & Martínez 2003, Schwarz 2007, Rodríguez et al 2012. In Mexico, there have been studies on the cultivation of D. latifrons (Basto-Rosales et al 2019), on the quality of its meat (López-Huerta et al 2018, Basto-Rosales et al 2020, and the nutritional requirements of juvenile fish (Badillo-Zapata et al 2018). However, alternative diets on the growth and production costs of this species have not been studied yet.…”

Groups of Dormitator latifrons in triplicate (4.1 ± 2.0 g and 6.2 ± 1.0 cm) were fed experimental diets containing four levels of substitution of fishmeal (FM) by soybean meal (SM) (0, 40, 70, and 100%, respectively). The diets were formulated to be isoproteic (35% crude protein) and isolipidic (8.0% crude lipids). The effect of each treatment on growth was evaluated and its implications on the cost of feeding. After 60 days of feeding, there were no significant differences in the fish's proximate composition (P < 0.05). There were no significant differences between the diets (P < 0.05) in the evaluated biological indices: total growth increase (TGI), specific growth rate (SGR), thermal growth coefficient (TGC), and survival (%). Feeding costs decreased significantly as the proportion of soybean meal in the diet increased. The results indicated that substituting FM by up to 100% of SM can promote adequate growth in D. latifrons without affecting body composition and survival while also reducing operative costs during the fattening process.

“…This species represents a food source [15,16], and in Ecuador it is of great economic importance for coastal communities, where it is cultivated in an artisanal way for consumption and export [17]; moreover, in Mexico and Nicaragua, there is interest in developing its production by aquaculture [18]. Indeed, D. latifrons due to its high-quality flesh, fast growth rate and low protein requirements has been identified as a possible candidate to replace tilapia species [19,20] that are cultivated in Ecuador in order to mitigate the impact of these invasive cichlids on Ecuadorian biodiversity [21]. Thus, any effort made to improve basic research on the species is of great importance for the development of cultivation programs.…”

The freshwater fish species Dormitator latifrons, commonly named the Pacific fat sleeper, is an important food resource in CentralSouth America, yet almost no genetic information on it is available. A cytogenetic analysis of this species was undertaken by standard and molecular techniques (chromosomal mapping of 18S rDNA, 5S rDNA, and telomeric repeats), aiming to describe the karyotype features, verify the presence of sex chromosomes described in congeneric species, and make inferences on chromosome evolution in the genus. The karyotype (2n = 46) is mainly composed of metacentric and submetacentic chromosomes, with nucleolar organizer regions (NORs) localized on the short arms of submetacentric pair 10. The presence of XX/XY sex chromosomes was observed, with the X chromosome carrying the 5S rDNA sequences. These heterochromosomes likely appeared before 1 million years ago, since they are shared with another derived Dormitator species (Dormitator maculatus) distributed in the Western Atlantic. Telomeric repeats hybridize to the terminal portions of almost all chromosomes; additional interstitial sites are present in the centromeric region, suggesting pericentromeric inversions as the main rearrangement mechanisms that has driven karyotypic evolution in the genus. The data provided here contribute to improving the cytogenetics knowledge of D. latifrons, offering basic information that could be useful in aquaculture farming of this neotropical fish.
