Abstract

The activities of this community about the utilization of tofu dregs and water hyacinth as catfish feed in tarpaulin ponds that have been done in Lubuk Siam Village, Siak Hulu Sub-District, Kampar Regency, Riau, the form of public awareness and training. The purpose of this activity is to providing knowledge and application of techniques about making feed catfish from the tofu dregs and water hyacinth are fermented with the EM4 for catfish farming in tarpaulin ponds. On the implementation of this extension and training activities using methods lectures, discussions and demonstrations. The target fish farmers/partners and the community on Hamlet I in Lubuk Siam Village. Results and achievement of targets have provided solutions to overcome the problem of catfish feed costs and the length of the production/harvest period (± 6 months) in the cultivation business it does to ± 3.5 months by minimizing feed costs from Rp.17,000-Rp.20,000/kg to Rp.3,000-Rp.5,000/kg, so you can save on fish feed costs by 50-60%. This Community Service activity received a positive response from the Village Head and village officials and the people of Lubuk Siam Village. Efforts to empower the community of Lubuk Siam Village, it can be seen that the partners have succeeded in making their own feed, adding to the partner's income for a pool measuring 10 m x 16 m with a dense thickness of 25,000-30,000 head of Rp.3,000,000-Rp.4,000,000/month and can improve family nutrition.

Abstract

Sail River is a sub-watershed of the Siak River in Pekanbaru City with various community domestic activities that cause the waters to be polluted by waste. One of the organisms that is tolerant of poor water quality is microalgae. The aims of this research to determine the potential microalgae in the Sail River. This research was conducted in September-December 2021 using a survey method. There were 4 sampling areas and in each sampling area there were 3 sampling points. Sampling were taken once/week for 3 weeks. Water quality parameters observed were temperature, transparency, pH, DO, CO2, nitrate and phosphate. The microalgae found were then isolated and culture in the laboratory, cultured in water media with Walne fertilizer added and their growth was observed. The results of this study shown that the microalgae found consisted of 2 classes, namely: Chlorophyceae (16 species) and Cyanophyceae (5 species). The isolated microalgae were: Chlorella vulgaris, Coelastrum microporum, Scenedesmus quadricauda, Pediastrum biradiatum and Merismopedia punctata. Microalgae isolates reached peak growth on the 7th to the 8th day. Meanwhile, the harvested biomass ranged from 0,05 g/L to 0,3 g/L. Based on the results of this research, it can be concluded that these five types of microalgae isolates are potential to be utilized.

Abstract

Microalgae live in almost all types of waters, including in groundwater. The diversity, fertility, and development of microalgae species in ponds are strongly influenced by the conditions and fertility of the waters. This study aims to determine the types of microalgae found in the Pekanbaru City Pond Waters. This research was conducted in Aquatic Biology Laboratory Faculty of Marine and Fisheries, Riau University by survey method. Sampling locations consist of 4 stations and 3 sampling points. The results showed that there were 13 species of microalgae found in ponds in Pekanbaru City, namely: Scenedesmus quadricauda, Pediastrum duplex mey, Tetrastrum heteracarthum, Spirulina platensis, Microcystis aeruginosa, Chlorella vulgaris, Scenedesmus dimurphus, Pediastrum duplex var, Closeterium parvulum, Coelastrum microforum, Scenedesmus acuminatus, Pediastrum biradiatum and Scenedesmus obligus. Based on laboratory culture results, the highest abundances of microalgae were Scenedesmus quadricauda, Spirulina plantensis and Chlorella vulgaris.

Abstract

Thynnichthys thynnoides is a freshwater fish found in Kebun Nopi Lake. This fish has economic value and is often caught by fishermen. A study aims to determine the growth pattern of T. thynnoides. The study used a survey method. Sampling was carried out 4 times from March-April 2022. The results showed that 107 fish captured consist of 39 females and 68 males.  T. thynnoides from the Danau Kebun Nopi has TL 83-165 mm, SL 58-130 mm, HDL 18-30 and weight 5,61-42,04 gr. The meristic characteristic of the fish were as follow: D.I.8-10, P.10.4-7, V.1.7-8, A.1.5-7, C.2.16-18, 20-22 pre-dorsal fin scale, 44-48 around the body scale, 14-20 caudal peduncle scale and 57-60 lateral line scale. The relationship between length and weight of females showed positive allometric (b=3,26) and males showed negative allometric (b=2,62). The condition factors from 0,6854-1,2858 where females were generally in better condition than the males.

Abstract

Parit Lake is one of the Oxbow Lakes located in Parit Baru Village, Tambang District, Riau Parovince. The lake is overgrown with various kinds of aquatic plants that almost cover the surface of the lake. This study aims to determine the diversity and percent covers of aquatic plants carried out in July 2022. The method use in this study is a survey method, where Parit Lake is used as a research area and the method use in observation of aquatic plants is the Belt Transek method. Menwhile, the method use in measuring water quality is direct observation and laboratory scale. Sampling of aquatic plants is carried out 1 times in a period of one month. The aquatic plants obtained were identified based on Van Steenis (1981). The results showed that there are 5 species of aquatic plants divided into 3 classes and 5 families, namely Eichhornia crassipes, Salvinia molesta, Limnocharis flava, Ipomea aquatica, and Cyperus rotundus. The diversity index of aquatic plants species in Parit Lake is relatively low with a value of 0,7. The percent covers of aquatic plants is relatively tight with a value of 60% with the highest covers of the Salvinia molesta species at 25%, while the lowest in the species Limnocaris flava is 3,75%.

Abstract

Puntius schawanefeldii is one of common fish in the Koto Panjang Dam. This fish commonly present around the floating cage culture area. Small P. schawanefeldii sometimes enter the culture cages and become trapped in the cages as they grew up. Farmers used to remove the trapped fish and put them in the cage around the cage culture area. The net caged P. schawanefeldii were not given any food, but they were able to grow. To understand the feed consumed by the caged fish and compare it with the free living fish, a study on the stomach content analysis of the caged and free living fish has been conducted on September 2022. Samplings were conducted 2 times, once/2 weeks and the stomach contents was analyzed using a volumetric method. There were 139 fishes captured. The stomach 104 fishes were full or partly full, while the stomach content of other 35 fishes were less than 25% and could not be analyzed. Results shown the stomach content of the caged and free living fish were similar, there were algae and pellets (they could not be separated), fish feed pellet remains and fish tissue remains. The Preponderance Index of each food type present in the caged fish are pellets 71.24%, mixed algae and pellets 26.76%  and fish tissue remains 2.00%, while those of the free living fish are  pellets 16.28%, mixed  algae and pellets 70.63%, and fish tissue remains 11.44%. Data obtained in this research indicate that the caged fish receive fish feed pellets that spilled out from the culture floating nets in the surrounding area.
