Bioekologi Udang Galah (Macrobrachium Rosenbergii) Di Desa Kuala Cenaku Kecamatan Kuala Cenaku Kabupaten Indragiri Hulu Provinsi Riau

---

Giant prawns (Macrobrachium rosenbergii) are freshwater and brackish fishery commodities with high economic value, both for local and export markets. In 2008 the production of giant prawns in the Kuala Cenaku River experienced a significant decline. This is due to changes in water quality after the input of peat water from land conversion activities around the river. As a result, giant prawns cannot adapt and experience disturbances in their growth and development. Currently there is no longer peat water input into the waters of the Kuala Cenaku River, so it is assumed that the Kuala Cenaku River has improved, so that the life of giant prawns is also good. Based on the above assumptions, the population of giant prawns in Kuala Cenaku is already large. This is in accordance with the catch of giant prawn fishermen in the local area, therefore it is necessary to study the bioecology of giant prawns (M. rosenbergii) in the waters of Kuala Cenaku Village.
This study aims to analyze the biological aspects of giant prawns (M. rosenbergii) after land conversion, and to analyze the characteristics of suitable habitats for the survival of giant prawns (M. rosenbergii) in the waters of Kuala Cenaku Village.
This research was conducted in May-July 2020 using the survey method. The giant prawn samples were collected by fishermen from 4 predetermined station points using traps and nets. Water quality measurements were also taken at 4 stations where the shrimp fishing gear was placed.
The analysis was carried out using descriptive analysis of the water quality of Kuala Cenaku Village waters, for the biological aspects of giant prawns which included shrimp abundance, growth patterns, condition factors, growth rates, exploitation and recruitment using the Fisat II application, while to analyze the phenotic conditions and kinship of giant prawns performed using PCA (Principal Component Analysis).
The condition of the waters of Kuala Cenaku Village has gradually recovered after the land conversion that occurred in the area. This is indicated by the water quality that supports giant prawns to grow and develop. Good environmental conditions are directly proportional to the availability of natural food in nature which is sufficient so that giant prawns can live well. Giant prawns in the waters of Kuala Cenaku Village were found with varied sizes with a balanced number of males and females. This indicates that the reproductive process is running well in this habitat. But poor conditions after deforestation cause shrimp to experience stress and have to adapt to these conditions. This is indicated by a decrease in the maximum size of prawns where in a previous study in 2008 found giant prawns with a size of about 30-35 cm while in this study it decreased to 25 cm. On the other hand, pressure on fishing activity for giant prawns also affects the survival of giant prawns.
