“…[27] stated that even though Laut Tawar Lake is an oligotrophic waters (poor in nutrients), the supply of nutrients that enter the waters is good for periphyton growth. This is supported by the opinion [28] stating that the presence of periphyton is an indicator in predicting the condition of a waters because the periphyton is relatively immobile and its life cycle is short, so that the periphyton is able to respond to changes in a waters. The abundance of periphyton in the waters is caused by the influence of the pH of the waters which are neutral and even alkaline [29].…”

Many activities are carried out around the Laut Tawar lake, one of which is the cultivation of floating net cages that can contribute nutrients to the waters. One of the organisms that can take advantage of the abundance of nutrients in the waters is periphyton. This study aims to examine the community structure of periphyton as natural food in Laut Tawar Lake. This research was conducted in January-April 2022. The results showed that there are 9 classes of periphyton at the KJA station, namely Bacillariophyceae, Chlorophyceae, Cyanophyceae, Rhizopoda, Dinophyceae, Euglenophyceae, Trebouxiophyceae, Klebsormidiophyceae and Coscinodiscophyceae. While, at non-KJA stations there are 7 classes where the Klebsormidiophyceae class and the dinophyceae class are not found at non-KJA stations. The highest abundance at the KJA station was on the 7th day with a value of 108,655 cells/cm2 and non-KJA was 24,552 cells/cm2. The lowest abundance occurred on day 14 at both stations. Periphyton diversity index at KJA and non-KJA stations ranged from 1.88-2.76, which was moderate. The evenness index of periphyton species ranging from 0.61-0.75 was classified as high, while the dominance index ranging from 0.09-0.24 was classified as low. Based on the values obtained, the community structure of periphyton on artificial substrates in the KJA and non-KJA areas in Laut Tawar Lake experienced moderate ecological stress with the community in a stable condition. The t-test results obtained that the abundance values at KJA stations and non-KJA stations had the difference that the abundance of periphyton at KJA stations was greater than at non-KJA stations.

“…Thus, the susceptibility to environmental changes makes zooplanktonic communities an indication of the intensity of these changes (Eskinazi-Sant'Anna et al, 2013). In addition, the abundance of these organisms in the nursery, which are a source of food for the fish, reduces the need to supply artificial food, that is, there is less generation of effluents with polluting potential (David et al, 2022).…”

Aim This study aimed to evaluate the interference of intensive fish farming in the physicochemical variables of water and in the zooplankton community from a tilapia (Oreochromis niloticus Linnaeus, 1758) pond in southern Brazil. In addition, it was verified whether the analyzed zooplankton groups could be bioindicators of changes in the quality of pond water. Methods The water and zooplankton sample collections were carried out monthly in different places of the pond: at the water supply site (affluent), in the middle of the pond and at the water outlet site (effluent). Analyzes related to nitrogen series (total nitrogen, total ammonia, nitrite + nitrate), dissolved oxygen, total hardness, total alkalinity, total phosphorus, pH, turbidity and water temperature were performed at all sampling sites. In addition, the density of the zooplankton groups Copepoda (adults and nauplii), Rotifera and Cladocera was determined. Results Regarding the changes between the quality variables of the affluent and effluent water of the pond, the outlet water showed a significant increase only in the variable total alkalinity. Rotifers were the most abundant organisms, and nauplii Copepoda showed a significant increase in the density of organisms in the middle of the pond compared to the inlet water. Both the redundancy analysis (RDA) and the Spearman correlation matrix revealed that zooplanktonic groups are associated with certain physicochemical variables of the water. According to the Analysis of Indicator Species (IndVal), the evaluated organisms are not related to bioindicator species in this environment. Conclusions Therefore, intensive production of O. niloticus caused changes only in the total alkalinity of the pond water. The zooplanktonic organisms correlated with the physicochemical variables of the water and between the groups, and did not show potential for bioindicators of water quality in the different locations of the pond.

“…The periphytic community forms the basis for many food chains, serving as food for various aquatic organisms, including some that are commercially important, such as tilapia (Oreochromis sp.) (David et al, 2022a(David et al, , 2022bGarcia et al, 2016;Garcia et al, 2017;Huchette et al, 2000;Ibrahim et al, 2023;Moraes et al, 2020;Moschini-Carlos, 1999).…”

“…In organic aquaculture, including substrates appears as an alternative, and the use of substrates occupying 30-40% of the pond area reduces 30-40% of the inputs spent on feeding at the density of 1.5 fish/m 2 (Milstein et al, 2005;Milstein et al, 2013). In Nile tilapia monoculture effluent, Nile tilapia can be produced without commercial feed inserting substrates for periphyton growth (David et al, 2022b).…”

As a productive and sustainable alternative to fish farmers, the present study aims to evaluate the use of substrate for periphyton growth in an Integrated Multitrophic Aquaculture (IMTA) with complementary species. The studied species were: Nile tilapia (Oreochromis niloticus), grass carp (Ctenopharyngodon idella) and curimbatá (Prochilodus lineatus). The experiment had four treatments with three replicates that evaluated the IMTAs: [T100] Cb:C – tilapia inside hapas fed on recommended feed, with grass carp and curimbatás outside the hapas making use of natural food; [T50] Cb:C – the same species distribution with tilapia fed 50 % of the daily amount of commercial diet. Cb:C 100 and Cb:C 50 – grass carp and curimbatás fed on recommended feed at two feeding rates (100% and 50%) with substrate for periphyton growth in the feeding restriction treatment. In phase II, tilapias were included in all the treatments as a complementary species. Growth performance of fish and physical-chemical parameters of water were evaluated. In the proposed models, the species were efficient in utilizing the feed and in nutrient cycling, achieving productivity of 6 t/ha in the system without water renewal. Inserting secondary and complementary species reduced the feed conversion ratio (FCR) to values of 0.95 in systems under feed restriction and 1.28 in the groups that received 100% of commercial feed. Considering the reduction of the FCR and the high productivity, farmers can diversify their products in the same area without increasing inputs.
