I love these funky little dudes.

Forbidden boba but you're gonna need a smaller straw. This entire field of view is less than 0.2mm across.

COMPARATIVE STUDY OF FISH PRODUCTION IN RELATION TO PERIPHYTIC STRUCTURE IN FLOODPLAIN WETLAND ECOSYSTEMS | UTTAR PRADESH JOURNAL OF ZOOLOGY

Periphytic communities are an important part of the wetland ecosystem, and they are impacted by a variety of ecological parameters like as light, temperature, nutrients, and water space availability. Aquaculture based on periphyton has enormous potential for increasing fish production by around threefold. The current study was conducted for two years, from October 2018 to September 2020, in two floodplain wetlands with unique characteristics of both open (Amda beel) and closed (Suguna beel) systems. During the study, the periphytic community, soil and water quality, and beel fish production were estimated and measured at monthly intervals. Maintaining a healthy aquatic environment and producing sufficient fish food organisms in water bodies are two essential variables for increasing fish output. The periphytic population of the studied ecosystems is made up of a mixed population of diverse animals. The species diversity values clearly showed that both wetlands were suitable for sustaining a balanced population of periphytic fauna. The goal of this work is to analyse the state of fish production in relation to periphytic structure in different habitats where flowing and static circumstances were compared. The Suguna was more productive in terms of fish crop, with annual fish yields ranging from 1601.01 to 1688.58 kg ha-1yr-1. The big carp provided the most to production in this beel (54.17 - 87.53 percent ). During the investigation, the percent contribution of the miscellaneous category of fishes in Suguna ranged from 9.59 to 45.83. The Amda's yearly average fish production ranged from 353.76 to 442.85 kg ha-1yr-1. Miscellaneous species were a considerable input to the fish captures (about 62 percent ). Carps were responsible for 6.64 – 68.95 percent of Amda's fish production. The fish production in the open beel was found to be very low, despite the higher biomass of the periphytic community. This was primarily due to higher siltation rates, poor management, weed infestations and nutrient imbalances, and many other issues related to river connectivity, which resulted in natural fluctuations in the beel's water level. The situations in these beels are complicated, and a delicate balance is required to ensure long-term fish production and associated livelihood while also adhering to social and environmental standards.

Compositional signatures in acoustic backscatter over vegetated and unvegetated mixed sand-gravel riverbeds

Multibeam acoustic backscatter has considerable utility for remote characterization of spatially heterogeneous bed-sediment composition over vegetated and unvegetated riverbeds of mixed sand and gravel.
