“…Only five taxa were not found in the littoral zone (Asplanchna sieboldi, Brachionus falcatus, B. urceolaris, Filinia longiseta, and Trichocerca elongata), thus resulting in 107 rotifer taxa that were known up to now for the Esteros de Camaguán. The geographic distribution of Euchlanis dilatata lucksiana, Lecane decipiens, and Lepadella imbricata was extended, which had not been previously mentioned for the Orinoco River basin [50,51]. Moreover, the presence of Trichocerca tigris, previously registered by Hauer [52], Euchlanis dilatata lucksiana by Infante [53], Mytilina michelangelli and Trichocerca myersi by Michelangelli et al [23], Lepadella acuminata and L. latusinus by Medina and Vásquez [54], Synchaeta stylata by Saunders and Lewis [55], and Cephalodella forficula, Trichocerca braziliensis, and Lecane decipiens by Zoppi et al [25] should be highlighted since these taxa have not been cited again since their first report in the country.…”

Rotifers represent an important component of freshwater zooplankton. The high richness of taxa, particularly in littoral macrophyte zones of water bodies in tropical and subtropical flood-prone areas, is a repeatedly reported fact. However, studies on the composition of periphytic rotifers in the Neotropics are reduced and almost non-existent in some regions. A qualitative study on rotifers (Monogononta) associated with littoral aquatic vegetation and their seasonal variation was carried out in three flood-prone ponds in the “Esteros de Camaguán Fauna Reserve” in the Venezuelan plains. For the selection of the collection sites, the two-stage stratified method with proportional affixation was used. Samples of macrophytes and the water associated with them were taken in littoral zones. The percentages of occurrence and numerical frequency were calculated for each rotifer taxa. The faunal similarities and correlations within and between ponds in the same and different climatic seasons were estimated using the Jaccard and Spearman coefficients (α = 0.05), respectively. In total, 102 rotifer taxa associated with 11 species of aquatic macrophytes were identified. The genus Taphrocampa with two taxa plus ten other taxa, are new records for Venezuela and one of them for South America. The taxocenosis and the geographic distribution of the reported taxa reflect a typical composition of the littoral zones of tropical regions. The total richness of both planktonic associated with aquatic vegetation and periphytic assemblages were similar. The highest richness of rotifer taxa coincided with the rainy season and the lowest with the early rainy season. The rotifer fauna presented low similarity values within and between ponds according to seasonality and, with some exceptions, between planktonic and periphytic environments. The importance of sampling periphytic rotifers and the influence of the flood cycle, and the degree of macrophyte development in the structuring of periphytic rotifer communities, were confirmed.

“…Para el género Daphnia, Burns (2013) y González et al (2023) menciona que las dafnias desempeñan un papel importante como "herbívoros clave" en la transferencia de biomasa y energía hacia los niveles superiores como los peces. Edmondson & Litt (1982) reportan que el cambio importante que afectó el éxito de Daphnia evidentemente fue una disminución en la abundancia del depredador, ya que la introducción de peces exóticos como la tilapia (Oreochromis niloticus, Linnaeus, 1758) y otras especies de poecílidos (Heterandria bimaculata, Heckel, 1848), Poeciliopsis gracilis (Heckel, 1848), pueden tener efecto sobre la abundancia de las comunidades de zooplancton, por ser especies planctívoras en sus etapas juveniles y al depredar en mayor proporción a los cladóceros, como ha sido reportado para otros sistemas acuáticos (Elías-Gutiérrez et al, 1999;Enríquez et al, 2009;Gayosso-Morales et al, 2017;González et al, 2023;Nandini et al, 2005;Santiago, 2016).

Los cladóceros son crustáceos utilizados como alimento vivo para larvas de peces debido a su aporte nutricional y fácil cultivo. El objetivo fue identificar las especies de cladóceros presentes en ambientes acuáticos temporales y permanentes del estado de Morelos. Se tomaron algunos parámetros físicos y químicos, además de las recolectas del zooplancton, en un total de 130 cuerpos de agua. Se determinaron un total de 33 especies comprendidas en las familias Bosminidae, Chydoridae, Daphniade, Ilyocryptidae, Macrothricidae, Polyphemidae, Sididae y Moinidae, donde sobresalen por su abundancia y frecuencia las especies de la familia Daphnidae. Se reporta que en estos sistemas acuáticos se presentan las especies que son utilizadas como alimento vivo, como es el caso de Moina cf. micrura, Diaphanosoma birgei, Daphnia laevis y Daphnia cf. mendotae. Se registró a Moina wierzejski como especie que habita tanto en lagos, presas y embalses, la cual es utilizada como alimento para larvas de peces.
