“…Temperature remained significantly lower in the substrate tanks. This can be attributed to the shading of these tanks by the substrates as reported earlier by Keshavanath et al (2002). Alkalinity acts as a pH regulating buffering system of pond water (Tavares, 1994).…”

“…Earlier studies have also shown the superiority of bamboo as a substrate in fish culture (Hem and Avit, 1994;Azim et al, 2002). Keshavanath et al (2002) who obtained 41-75% increase in fish growth in non-fed substrate based tanks opined that substrates reduce the need for artificial feed and therefore, can be considered as an alternative to feeding in the culture of herbivorous fish.…”

“…Biodegradable substrates are considered to be better suited for periphyton growth because of the high C:N ratio. Herbivorous species such as rohu (Labeo rohita), fimbriatus (Labeo fimbriatus), mahseer (Tor khudree) and tilapia (Sarotherodon niloticus) are more suitable for exploiting periphyton (Azim et al, 2001;Keshavanath et al, 2002;Uddin et al, 2009) to effectively utilize periphyton from bamboo substrate (Amisah et al, 2008). However, such studies using native fish species in Brazil are very limited.…”

Two experiments were conducted using plant substrates viz. bamboo (Bambusa vulgaris), ambay (Cecropia pachystachya) and leucaena (Leucaena leucocephala) without and with fish to evaluate their suitability for periphyton development, and influence on water quality and growth performance of jaraqui (Semaprochilodus insignis). In the first experiment of 45 days, carried out with only the substrates, periphyton growth and water quality were assessed, while in the second experiment of 120 days fish growth was monitored, in addition to periphyton development and water quality. The best growth of periphyton was observed on bamboo, followed by ambay and leucaena. Bamboo grown periphyton had the highest chloropyll-a (39.59 µg/cm 2 ) and protein (24.42%) content. All the water quality parameters monitored were within the limits suitable for aquaculture. Fish of av. length 6.5±0.15 cm and av. wt. 5.83±0.23 g stocked at a density of 1 per m 2 attained the best final av. length of 11.23±0.69 cm and av. wt. of 34.34±2.05 g in bamboo installed tanks, indicating its superiority as a substrate. Jaraqui growth was higher by 76.65, 53.55 and 25.41% in bamboo, ambay and leucaena treatments over the control with no substrate.

“…While in substrate-free tilapia ponds, a coefficient between net fish yield and chlorophyll a of R 2 = 0.89 was noted by Almazan and Boyd (1978). The enhancement of fish production from 41 to 75% by periphyton alone was reported by Keshavanath et al (2002).…”

“…The assemblage of attached organisms on a submerged surface, including associated non-attached fauna, is referred to as periphyton (van Dam et al, 2002). In aquaculture, they have been used to improve water quality and the production of the culture species (Khatoon et al, 2007).…”

The growth, production and survival of Nile tilapia Oreochromis niloticus, with an average individual weight of 0.2 g were used to determine the density-dependent growth and production relative to phytoplankton and periphyton biomass in periphyton-based aquaculture. The trial was conducted in 10 m 2 concrete tanks for a 56 day period. A 10 cm layer of soil was placed at the bottom of each tank. To act as substrates for periphyton, bamboo poles with an approximate submerged surface area of 50% to that of the total tank surface area were vertically posted in the tank bottom. A weekly fertilizer dose of urea and triple superphosphate at a rate of 28 kg N and 7 kg P/ha/week was added. Four stocking densities in triplicate were used: 5, 10, 20, and 40 fish/m 2 (50, 100, 200, and 400 fish/tank). The results indicated that the carrying capacity of periphyton-based tanks for Nile tilapia was 293 g/m 2 in a 56-day culture period. The relationships between gross yields of tilapia (y) and periphyton dry matter (x), or chlorophyll a (x) were described as y = 353.2483-109.1809x, R 2 = 0.5646, P = 0.005, y = 125.5916 + 0.9698x, R 2 = 0.5841, P = 0.004. Provision of substrates at 50% of total tank surface area was sufficient for periphyton production in nutrient-rich aquaculture ponds where grazing rate and fish density in the system are balanced.
