“…Pronounced seasonal variations also occurred, although data were not tested for statistical significance, in the Raritan River, NJ (Flemer, 1970), Fort River, MA (Sumner & Fisher, 1979), River Arakawa, Japan (Tominaga & Ichimura, 1966), River Thames and River Kennet, England (Kowalczewski & Lack, 1971). However, seasonal differences in respiration in the Blue River, OK were not striking (Duffer & Dorris, 1966).…”

“…For example, the metabolism of stream communities has been measured using gas changes in chambers for partial day (McConnell & Sigler, 1959;Bombowna, 1972;Marker, 1976b;Sumner& Fisher, 1979) or entire day incubations (Pennak & Lavelle, 1979;Naiman, 1983). Open system gas techniques were employed to estimate annual metabolism for a single reach (Odum, 1957;Hall, 1972;Fisher & Carpenter, 1976;Simonsen & Harremoes, 1978;Cushing& Wolf, 1982), to derive single season data for several river reaches (H oskin, 1959;Wright & Mills, 1967;Hornberger et al, 1977), and in two instances to measure metabolism in more than one reach at several times of year (Duffer & Dorris, 1966;Flemer, 1970). Isotopic procedures also have been employed to estimate periphytic (Elwood & Nelson, 1972;Naiman, 1976;Bott & Ritter, 1981;Hornick et al, 1981) and planktonic (Wissmar et al, 1981) …”

Benthic community metabolism in four temperate stream systems: An inter-biome comparison and evaluation of the river continuum concept

et al. 1985

Benthic community metabolism was studied on four stream systems located in different biomes in the United States: the eastern deciduous forest (Pennsylvania, PA, and Michigan, MI), the high desert (Idaho, ID), and the coniferous forest (Oregon, OR). Studies were designed to test the hypothesis advanced within the River Continuum Concept that a transition in community metabolism will occur from a predominance of heterotrophy in headwaters to a predominance of autotrophy in mid-sized reaches, with a return to heterotrophy further downstream. Both gross primary productivity (GPP) and community respiration (CR 24 ) increased with downstream direction on all systems. Net daily metabolism (NDM, or GPP -CR 2 4 ) shifted from heterotrophy (-NDM, GPP < CR 24 ) to autotrophy (+NDM, GPP > CR 2 4 ) with downstream direction at all sites, supporting the hypothesis. Annual metabolism in the most upstream reach of all sites was dominated by respiration; however, the farthest downstream reach was not necessarily the most autotrophic. Site-specific factors affected manifestation of the trend. Photosynthesis predominated annual metabolism in reaches (designated 1-4 in order of increasing size) 2-4 in ID, 3 and 4 in OR, and 4 in MI. In PA annual photosynthesis was slightly greater than respiration only at Station 3. Photosynthesis was predominant most consistently in ID and respiration most often in PA. About half the reaches that were heterotrophic annually were autotrophic at one or more seasons. Annual means of benthic GPP, CR 24 and NDM ranged from 0.16 to 3.37, 0.36 to 2.88 and -0.73 to 0.50 g 02 m 2 d 1, respectively. Metabolic rates were usually high in PA and Ml (and sometimes ID) and almost always lowest in OR. Parameters accounting for most variance in multiple linear regression analyses of the combined metabolism data from all sites were indicators of stream size, photosynthetically active radiation, temperature, and chlorophyll a concentration.

“…There is little doubt that large stones have a well established flora, whilst small ones may be so moved during periods of high flow that the flora is reduced (Duffer & Dorris, 1966;Marker & Willoughby, 1988) and at the time of sampling the flora may be in a stage of progression towards a more stable community; small stones may in fact never reach the same floral composition as large. The effect of position in the stream (marginal or nearer the centre) may affect the flora; the orientation of the surface of the stone (facing upstream or downstream) does affect the composition of the flora (Cazaubon & Loudiki, 1986;Stevenson, 1983;Stevenson et al, 1985;Snoejis, 1988).…”

Diatoms in river water-monitoring studies

1991

View full text Add to dashboard Cite

Diatoms grow abundantly in rivers, colonising almost all suitable habitats. They have been used extensively in studies related to the monitoring of water quality. This review attempts to draw together data from a wide variety of approaches. The advantage of sampling discrete habitats is stressed and particular attention is paid to the diatom flora of stone surfaces (epilithon) which is the favoured source in many studies. The advantages and drawbacks of the techniques are discussed and some hopefully helpful suggestions made. The historical development of the topic is briefly surveyed, but no attempt has been made to present a comprehensive review of the literature which has increased enormously in the last few decades.

“…Huda et al [79] in their study in rice-fields of Bangladesh reported the periphyton based aquaculture as economically viable technology for increasing fish production with cheaper local resources. Duffer and Dorris [80] suggested that the substrate type rather than light intensity or nutrient was the effective agent in periphyton based system. When compared to artificial substrates, studies revealed that periphyton develops better on natural substrate due to its differences in the hydrophilic characteristics [81].…”

Periphyton is being used traditionally as rich aquatic feed for fishes throughout the countries like Cambodia, West Africa, Srilanka, India and Bangladesh. In waterlogged rice environment, it can be judiciously utilized as feed source introducing periphytophagous fish. Studies supported rice straw as suitable substrate for periphyton growth. The study of gut content of Common carp (Cyprinus carpio L.) from a periphyton-based rice-fish culture system in Apatani Plateau of Arunachal Pradesh, India showed maximum of 60 genera of microflora and fauna with periphytic in nature. The farmers from this rice-fish culture practice are gaining an average fish production of 500kg ha -1 180 day -1 without employing any supplementary feed. Better selection and determination of appropriate stocking density of periphytophagous fish in waterlogged rice-fields might extend the rice-fish culture towards a sustainable and self-substrating periphyton based aquaculture (SSPBA) practice.
