“…The present study found that the results in the fish assemblage composition were in line with the proposals of these studies, through the changes between flood and drought. In wetlands that are exposed to seasonal changes between drought and flooding, there are three strategies for fish reproductive in these wetlands (seasonal strategy, equilibrium, and opportunistic strategy), especially in the assemblage which occur in the temporary pools [1,19,20]. Fish in temporary pools must adapt to successfully survive a period of drought that is strict on evolution and life history.…”

“…In some years, there is a complete dryness of the temporary and permanent pools, so there is a complete extermination of the fish communities and the new fish offspring are small, but in other years, the permanent pools remain to replenish stocks. In the second case, the permanent pools that did not dry up are used as a stockpile to restore the communities of fish to their previous state, and the size spectrum of fish is relatively large [1,20,38]. The ecological indices are important to measure the biological communities, species abundance, monitor temporal and spatial effects of drowning and drought, decline of water depth, and pollution in freshwater environment, and their impacts on fish assemblage [39].…”

“…Occasional fish species catch from one to 5 months. Response to succession drought and flooding on size spectrum of fish assemblage in Zachery marsh the assemblage composition patterns, species life-history strategies are identified into three groups: equilibrium, periodic, and opportunistic according to [19,20]. The dominance index for the most abundant three fish species was…”

The present study was implemented in the Zachery Marsh as part of the middle marshes north of Bashar Province from January to December 2022 to investigate the impact of the seasons’ oscillation between drought and flooding on fish assemblage abundance, size spectrum, and ecological indices. Three stations were selected to collect samples of fish. The specimens were monthly gathered with different fishing tools, including fixed gillnets, cast nets, and electrofishing. The water temperature ranged from 12.32 to 34.03 °C, the salinity varied from 1.75 PSU to 2.89 PSU, and the pH fluctuated between 7.47 and 8.43. The rate of change in water depth in the low flat regions fluctuated from 27 cm in September to 76 cm in April. The mean water depth in rivers, small pits, and canals varied from 45 cm in October to the highest, 121 cm in March. In the seasonal regions, the average depth ranged from zero in July, August, September, and October to 40 cm in April. The current study documented 18 fish species belonging to 16 genera and 9 families from Zachery Marsh, all of them affiliated with the Osteichthyes class. Cyprinidae was the most abundant family, including six species. The species Planiliza abu, the most abundant species, formed 28.44%, Carassius gibelio constituted 20.27%, and Orechromis aureus represented 18.52%. The dominance index (D3) of the three dominant species was 67.23%. The size spectrum of the most commercial species was determined. The diversity index value ranged from 1.64 in August to 2.08 in June, the evenness index varied between 0.69 in May and 0.91 in December, and the richness index values fluctuated from 1.47 in August to 2.28 in June. Resident species represented 88.02%, seasonal species formed 6.08%, and the occasional fish species counted for 5.90%. The present study concludes that the fluctuation between drought and flooding has a critical role in the composition of fish assemblages, particularly in seasonal marshes that are subjected to extreme conditions. The fish evolve several reproductive strategies in these difficult conditions in order to survive and continue.

The present study reports the seasonal dynamics of the fish community structure in the presence of a non-native fish (Pterygoplichthys pardalis) in tropical waterbodies of southern Mexico. The studied floodplain existed in both connected pools and disconnected pools “to the Palizada river”. Local fish fauna showed consistent assemblages across seasons, but among the 17 local fish species recorded, the non-native species P. pardalis showed the highest percentage of contribution to the fish community (ca. 20%). Conversely, the frequency of occurrence and density of the non-native species showed variation in relation to the type of waterbody and seasonality; its density was approximately four times higher in disconnected pools than in connected pools in the rainy season and its predominant size class in both pool types was 21-30 cm in standard length. Interestingly, the diversity of the native species was negatively related to the density of the non-native species, indicating that the presence of P. pardalis can be a factor involved in the decline of native fish diversity in these local communities. Currently, the possible impacts of the presence of P. pardalis on local fish diversity at the regional scale are unknown, but our results suggest that hydrological dynamics regulate the establishment of the non-native species in this region. However, future studies are needed to provide insights into the actual scenario of P. pardalis distribution in Yucatan Peninsula and the possible impacts on the native fish fauna in southern Mexico.

From January to December 2019, the composition of fish assemblages in Al-Huwyzah marsh was studied in various ways based on the nature of their life-history strategies. In orders to assess the impact of hydrological variations on fish assemblage composition, diversity, and abundance. Water temperature fluctuated from 12°C in January to 33°C in July. Salinity varied from 1.38 g/l in March to 3.87 g/l in November. Hydrogen ion fluctuated from 7.37 in November to 8.18 in December. Monthly fluctuations in water depth were monitored for flat sections and low-lying areas of the marsh. Fish assemblages in Al-Huwyzah marsh were studied to determine the impact of hydrological and environmental changes on the pattern, abundance, diversity, and richness of fish assemblages. Fixed, drift, and cast gillnets were used to catch the fish. Nine thousand eight hundred fifty-three fish specimens belonging to 18 species, 17 genera, ten families, and six orders were caught from the three selected stations. All of which belonged to the Osteichthyes class. Ten fish species were native, and eight were exotic species. The Abu mullet Planiliza abu was the most abundant species comprising 35.74% of the total number of species, Prussian carp Carassius gibelio 19.74% of the total caught, and blue tilapia Oreochromis aureus 19.23%. The dominance index (D3) ratio is 74.71% of the upper abundance of three fish species in the present area. The equilibrium strategists that prefer stable habitats with a long time breeding season include abundant exotic species, and opportunistic strategists comprise one species of present fish assemblage.
