Abstract

Dumbo fish are economically valuable fish, consumer demand is high enough, but not yet accompanied by intensive and optimal effort. One attempt to overcome this problem by substituting commercial feed with Golden Snail flour which has a high enough protein content as a protein. This study aims to determine the effect of flour on commercial feed on the growth of dumbo fish seeds. Fish is a 5-6 cm dumbo fish kept in size of 45x20x20 cm as many as 9 units arranged randomly. The research design was carried out with three parts: P4K0 (100% commercial feed), P3K1 (75% commercial feed + 25% conch flour), and P2K2 (50% commercial feed + 50% conch flour). The results showed that the golden snail flour can be used as substitution in fish feed, where the best yielding feed is P2K2 (commercial feed 50% + mas 50% cloves) with the length of 3.16 cm and weight 6.71 g, with a value of Conversion ratio of 1.22 and an 80% lifetime value.Keywords: Clarias gariepinus, Golden Snail Flour, Growth, Feed Conversion Rate, Survival Rate

Abstract

Tilapia (Oreochromis niloticus) is a freshwater fish that has high economic value and widely cultivated, but the cultivators often get problem in feed prices because the high cost of raw materials such as fish feedwhich is still imported. To overcome this problem, we look for alternatives to local raw materials that can replace fish feed such as shrimp head waste flour. This study aims to determine the effect of shrimp head flour on commercial feed on the growth rate of tilapia. This study used a complete random planning which is designed with 3 treatments and 3 replication, P1 (75% commercial feed + 25% shrimp head flour), P2 (50% commercial feed + 50% shrimp head flour), P3 (25% commercial feed + head flour 75% shrimp). The data obtained were analyzed by variance and continued with Duncan's test. The parameters that observed were heavy and long growth, and the Feed Convertion Ratio (FCR). All parameters were showed that the use of shrimp head flour in artificial feed gave a very significant effect on the growth rate of tilapia with high growth values, while the FCR value was low. The high content of shrimp head flour in feed causes increased growth of tilapia. The results showed that the highest increase in length and weight with feed in P3 was found significant effect with value of length of 5.7 cm and weight of 21.2 g and the highest survival rate at P3 treatment of 80% and feed conversion ratio (FCR) of 0.8%.Keywords: Shrimp Head Flour, Growth Rate

Abstract

Tilapia is a freshwater fish that has widely cultivated and is very popular among the community. In tilapia aquaculture, the most important factors are growth and survival rate as well as sufficient feed requirements. This research aims to determine the effect of EM-4 on commercial feed towards the growth and survival of tilapia, as well as knowing the number or frequency of EM-4 which is effective against the growth and survival rate of tilapia (Oreochromis niloticus). This research was conducted from April to June 2018. During the study of fish were given commercial food mixed with EM-4. Feed were given of 5% from body weight. The frequency of feeding were given 3 times a day at 08.00 am, 01.00 pm and 05.00 pm. The design that have been used in this study was Complete Randomized design with 3 treatments and 3 repititions namely : P1 ( EM-4 8 ml / kg commercial feed), P2 (EM-4 12 ml / kg commercial feed) and P3 (EM-4 16 ml / kg commercial feed). The results of these research were used analyzed by SPSS program. The results showed that the giving of EM-4 significantly affected the length and weight of fish but did not significantly affect the survival rate of tilapia. The higher growth of length and weight was found with P3 and mixed of EM-4 16 ml / kg of feed and the higher survival rate was found in P3 and mixed of EM-4 16 ml / kg commercial feed.Keywords: Effective Microorganism-4, Growth Rate

Abstract

Catfish is a freshwater species that is widely cultivated and consumed because easy to process, and very popular in the society. One of many hindrances in aquaculture of catfish for business is that the feed frequently used by the community costs much, resulting in farmers using feed pellets like tuna-waste flour mixture as an alternative additional feed. Therefore, this research aims to determine the sufficient usage of the tuna-waste flour mixture in commercial feed to growth of catfish as well as the growth increase and the survival rate of catfish with additional tuna-waste flour mixture in its feed. This research was conducted on April to June 2018. The design were used Complete Randomized Design with 3 treatments and 3 repetitions, namely P1 treatment (80% Commercial Feed + 20% Tuna-Waste Flour), P2 (65% Commercial Feed + 35% Tuna-Waste Flour), P3 (50% Commercial Feed + 50% Tuna-Waste Flour). Statistic analysis were used the SPSS version 21.0 and the result was analyzed by using Analysis of Variance (ANOVA) and the Duncan test. The result of the research data shows that the most significant increase was found in P3 treatment, with 8 cm average increase in length and of 24.71 gr average increase in weight and the highest survival rate was found in P3 treatment as higher as 80.56% as well as FCR is 1.31%.Keyword : Catfish (Clarias sp.), Tuna Fish Waste Flour, Growth Rate, FCR

Abstract

Sungai Mombang banyak dimanfaatkan masyarakat untuk kegiatan sehari-hari. Kegiatan tersebut tentunya memberikan dampak dan tekanan terhadap perairan sungai sehingga dapat menjadi ancaman serius bagi kelestarian dan keanekaragaman hayati ikan di perairan. Penelitian ini bertujuan untuk mengganbarkan keragaman ikan di Sungai Mombang, Kecamatan Batangtoru, Kabupaten Tapanuli Selatan. Titik lokasi pengamatan terdiir dari 4 lokasi. Ikan ditangkap dengan alat backpack electrofishing dengan kekuatan arus lisitrik sebesar 9 ampere. Kondisi habitat yang di surveiyaitu: suhu, DO, BOD, nitrat, fosfat, arus, kedalaman, dan kecerahan. Hasil penelitian di Sungai Mombang Kecamatan Batang Toru Kabupaten Tapanuli Selatan didapatkan 16 spesies ikan, yang termasuk ke dalam 6 ordo, 8 famili. Ikan Jurung dan Ikan Sidat merupakan ikan ekonomis yang terdapat di Sungai Mombang. Ikan-ikan yang ditemukan di Sungai Mombang merupakan ikan asli, kecuali Ikan Nila (Oreochromis niloticus). Diversitas ikan di Sungai Mombang tergolong tinggi dibandingkan dengan sungai-sungai kecil lainnya di Sumatera. Secara umum kondisi habitat ikan di Sungai Mombang termasuk baik dan layak bagi kehidupan ikan.

Abstract

Fitoplankton merupakan organisme yang sangat dipengaruhi oleh perubahan kualitas air. Fitoplankton dapat dijadikan sebagai indikator untuk mengevaluasi kualitas dan tingkat kesuburan suatu perairan. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman fitolankton dan hubungannya dengan kualitas air di Sungai Aek Pohon Kabupaten Mandailing Natal Provinsi Sumatera Utara. Penelitian dilaksanakan bulan Agustus-Oktober 2021 menggunaan metode purposive sampling dengan melihat pemanfaatan dan perbedaan kondisi lingkungan disekitar Sungai Aek Pohon pada 3 stasiun pengamatan. Kualitas Sungai Aek Pohon Kabupaten Mandailing Natal berdasarkan metode storet memenuhi baku mutu air sungai pada stasiun I dan III dengan nilai storet yaitu 0. Stasiun II dengan nilai storet yaitu -2 dikategorikan tercemar ringan. Berdasarkan indeks saprobik fitoplankton Sungai Aek Pohon dikelompokkan kedalam βMeso/Oligosaprobik dengan nilai saprobitas 1,1 dan termasuk kedalam perairan dengan kondisi tercemar ringan. Nilai keanekaragaman fitoplankton menunjukkan bahwa seluruh stasiun termasuk kedalam keanekaragaman sedang nilai keanekaragaman pada stasiun I yaitu 2,538, stasiun II yaitu 2,886 dan stasiun III yaitu 2,878. Hasil principal component analysis menunjukkan suhu, pH, DO, fosfat dan nitrat berkorelasi positif terhadap keanekaragaman fitoplankton dengan masing-masing nilai korelasi 0,417; 0,411; 0,081; 0,346 dan 0,433. Hubungan kecerahan dan kecepatan arus berkorelasi negatif (tidak searah) terhadap keanekaragaman fitoplankton dengan masing-masing nilai korelasi-0,052 dan -0,297.
