In the Amazon basin it is distributed the greatest diversity of freshwater fish in the world, but presents less than half of the species described and/or with little knowledge about its biology and distribution. This work presents the composition of the ichthyofauna Igarapé Praquiquara, located in the municipality of Castanhal, belonging to the Northeast Atlantic Hydrographic Region, Brazil, through collections were conducted in the years 2014 and 2015. A total number of 1,073 fish were sampled, belonging to five orders, 16 families, 35 genus and 42 species. Characiformes and Perciformes were the most predominant orders, Cichlidae and Characidae were the most abundant families, and Bryconops giacopinni, Cyphocharax gouldingi, Astyanax sp., Geophagus proximus and Satanoperca jurupari the most abundant species. Igarapé Praquiquara is composed of species with moderate commercial interest for commercial aquariums, with the presence of species cultivated in other regions. A structural analysis of the igarapé fish community is recommended in order to identify which factors are responsible for the composition of the ichthyofauna present, as well as the influence of the dam on the dispersion, distribution and reproduction of species.

Fish Collection

Fakfak and Kumawa Mountains are located in Bomberay Peninsula, Papua, a poorly known ichthyological record and was recommended by Conservation International for field inventory. This research was conducted from 6-15 February 2021 to document freshwater fish diversity in northern and eastern Fakfak toward Bomberay District. The fish was collected from creeks, streams, and rivers. The fish collection was done once in each location, mainly using a seine net, while a gill net was used in a few sites along Ubadari River. It was done for four hours, netting in one to three locations each day. Fish abundance was described based on common (C), occasionally (O), dan rare (R) scales. Freshwater fish data were descriptively identified. Twenty-two native New Guinean species belonging to 19 genera and 14 families were collected during the survey. There was no specific family dominant in the fish community. All fish recorded have widespread distribution, yet only one species has restricted distribution in the Vogelkop and Bomberay Peninsulas. One rainbowfish species was observed but not properly identified. This results as initial data of the fish community of Bomberay Peninsula, especially of Fakfak. Further research is needed to reveal the fish community from another part of the peninsula.

The Nui Chua National Park is one of the National Parks which has many high mountains beside East see in Vietnam. There are many small streams in the Nui Chua National Park which directly flow in East see without river. So their animals and plants are very diversities. Butis gymnopomus, a new freshwater fish species is recorded in Vietnam is an example for their diversity: The Butis genus has a species is described in Vietnamese documents is Butis butis, before. The Butis gymnopomus has characteristics differences with Butis butis: - D1 = VI, D2 = 9; P = 18; V = 6; C = 19; A = 1, 7-8 - There is a big black line sagittal following their body (start predorsal fin to origin caudal fin). - The cadal fin which equally soft rays. The first three rays are white color. The white color are decreased from the forth to nineth's. And the tenth to final are black color. - This species are described in Malaysia, Borneo, Celebes, Kabaena, New Guinea and Philippines.

Functional Richness

Background Freshwater fish populations are facing multiple stressors, including climate change, species invasion, and anthropogenic interference. Temporal studies of fish functional diversity and community assembly rules based on trait-environment relationships provide insights into fish community structure in riverine ecosystems. Methods Fish samples were collected in 2015 in the Min River, the largest freshwater riverine system in Southeastern China. Fish functional diversity was compared with the background investigation in 1979. Changes in functional richness, functional evenness, functional divergence, and functional beta diversity were analyzed. Relationships between functional diversity and environmental factors were modeled by random forest regression. Correlations between fish functional traits and environmental factors were detected by fourth-corner combined with RLQ analysis. Results Functional richness was significantly reduced in 2015 compared with 1979. Functional beta diversity in 2015 was significantly higher than that in 1979, with functional nestedness being the driving component. Reduction of functional richness and domination of functional nestedness is associated with species loss. Trait convergence was the dominant mechanism driving the temporal changes of functional diversity. Precipitation, temperature, species invasion, and human population were the most significant factors driving fish functional diversity. Higher precipitation, higher temperature, and presence of invasive species were significantly associated with higher swimming factor and higher relative eye diameter, while the opposite environmental conditions were significantly associated with higher pectoral fin length and eurytopic water flow preference. Conclusions Environmental filtering is the dominant temporal assembly mechanism shaping fish community structure. This work contributes to the understanding of temporal freshwater fish community assembly and the associations between fish functional structure and local environmental conditions, which will be informative for future freshwater fish conservation.

Abstract Freshwater fish diversity, abundance, the ecological indices, and water quality from Main Outfall Drain (MOD) in Al-Diwaniya City/middle Iraq were studied monthly from January to December 2017 in two sites. The present study has shown that the third river (MOD) supported 15 fish species belonging to 7 families. As far as biodiversity status in fish community (IUCN-2019) is concerned, out of 15 species, eleven fish species are categorized into Lower risk least concern (LC or LR/lc), four Vulnerable (VU). Eight species were sensitive to salinity; seven species were tolerance. The results were concluded that the properties of water were tolerable for the fish community. Ultimately, it can be concluded that the sector of MOD supported the fish community. But it needs constant monitoring for the conserve and development of the diversity and the case of the healthy fish.
