Fish cultivation business is one of the very promising business with the increasingly cheap demand of fishery products in the community. So is the case with the cultivation of Tilapia fish. Aquaculture is not spared from various obstacles and problems that often hamper fish farming is the occurrence of disease attacks. Tilapia fish Who was attacked The disease starts with by showing signs of behavioral changes. In addition to the behavior, tilapia also experience a change in color that looks very clear difference compared to fish that are still healthy. Calculation of condition factors, from the three sampling sites average fish is in poor condition indicating that most of fish in pond cultivation have decreased condition that reach 60-90%, caused by disease / phatogen factor or environmental factor not good.The results of the laboratory analysis found six (6) parasites that infect tilapia: Dactyloyrus sp, Gyrodactylus spp, Tricodina sp, Vortycella sp, Oodinium sp, and Saprolegnia sp. Water quality is less good in the cultivation are resulted in the decreased condition of fish and support well the development of various types of parasites.

Lake Batur is the largest lake in Bali with many activities surrounding that will have great impact on fertility of the lake. One key factor in the fertility of the lake is phytoplankton. Abundance of phytoplankton in the waters affected by several environmental parameters. This research was conducted at Lake Batur, Kintamani district, Bangli Regency, in February 2014. Study is to measure the composition, abundance, diversity, uniformity and dominance of phytoplankton in the waters, measuring parameters and aquatic physical chemistry. The diversity of phytoplankton species found in Lake Batur are 5 class consists of 20 genera. Phytoplankton abundance ranged from 232370-336325 ind/l are eutrophic lake. Phytoplankton diversity index were included in diversity, uniformity index is included in the low uniformity, dominance index showed no dominance. Physical and chemical parameters of water still shows a good value so that the waters of Lake Batur contamination has not occurred.

This study aims to determine the diversity of demersal fish and feeding habits and food habits of demersal fish found in the lower reaches of the Yeh Sungi River. This research was carried out in the lower reaches of the Yeh Sungi River, Tabanan, Bali. This research began on April 17, 2016 until May 1, 2016. The research method used is descriptive exploratory method, namely by conducting a series of sampling activities of demersal fish species to identify the diversity of species and behavior (feding habit) of each type of demersal fish, as well as the food habit of each type of demersal fish. The results of the research on the diversity of demersal fish that have been found in the lower reaches of the Yeh Sungi River are quite diverse, based on the results of the study which captured 14 types of demersal fish in the lower reaches of the Yeh Sungi River. Feeding habits of 14 species found in demersal fish have nocturnal properties, by identifying the physical characteristics of demersal fish, especially in the form of mouths and fins, knowing some types of demersal fish that have adhesive fins prove that the fish look for food by attaching (passively) to the substrate of river rocks and tend to eat moss and detritus and are omnivorous. Demersal fish that do not have adhesive fins tend to be carnivorous and omnivorous, often looking for food by grabbing their prey, especially on the sand substrate on the riverbed. According to the results of analysis of abdominal surgery from 14 types of demersal fish found, 10 body cut objects from macrozoobenthos animals or food habits both intact and destroyed which were then matched with macrozoobenthos data which had previously been found on the bottom substrate downstream of the River. Yeh Sungi, the body pieces are white worms, red worms, silk worms / Tubifek sp, subsequent snails, small shrimp, short snails, dragonfly larvae, insects, detritus and moss.

This study aims to determine the species composition, abundance and community structure of periphyton based on biological indices found in various types of substrates in giant prawn ponds (Macrobrachiun rosenbergii de Man). This research was carried out in July-August 2020 in the POKDAKAN Mina Anakan Jepun culture pond, Bebetin Village, Sawan District, Buleleng Regency and identification of periphyton was carried out in the Agricultural Analysis Laboratory, Faculty of Agriculture, Warmadewa University. This study used experimental methods and the data obtained were analyzed descriptively quantitatively. The substrates used are bamboo substrate, palm oil substrate, and PVC pipe substrate with a diameter of 5 x 10 cm2. Periphyton sampling was carried out once every 7 days for 28 days, namely at 07.00-09.00 WITA. The abundance of periphyton on bamboo substrates ranged from 31,338-62,828 ind/cm2, on palm sugar substrates between 33,936–47,083 ind/cm2, and on PVC pipe substrates ranging from 39,592-71,236 ind/cm2. The diversity index value on bamboo substrates ranged from 2.33-3.00, on palm substrates ranged from 2.42-2.80, on PVC pipe substrates ranged from 2.72-2.94. The uniformity index of periphyton on bamboo substrates ranged from 0.72-0.82, on palm oil substrates ranged from 0.70-0.80, and on PVC pipe substrates ranged from 0.81-0.83. The dominance index on bamboo substrates ranged from 0.10-0.19, on palm oil substrates ranged from 0.10-0.21, and on PVC pipe substrates ranged from 0.08-0.10.
