Abstract

The growth of Nirwana tilapia (Oreochromis niloticus) is strongly influenced by feed and environmental conditions in aquaculture systems. In Indonesia, tilapia productivity is often constrained by feed efficiency and fluctuating water quality. Natural feed such as bloodworms (Chironomus sp.) contains high protein levels that support length growth, while pellets provide complete nutrients for weight gain. This study aimed to evaluate the effects of bloodworms, pellets, and their combination on the growth performance of Nirwana tilapia fingerlings, as well as on water quality (temperature, pH, dissolved oxygen, and ammonia). A Completely Randomized Design (CRD) was applied with three treatments: A (15% bloodworms), B (5% pellets), and C (a combination of 7.5% bloodworms + 2.5% pellets), each with four replications. The fingerlings measured 3–4 cm and were approximately two months old, reared over a period of 50 days. The results showed that all treatments led to increases in weight and length; however, based on analysis of variance (ANOVA), there were no significant differences (p > 0.05) in all growth parameters: weight gain (2.20–2.22 g), length gain (1.32–1.48 cm), specific growth rate (2.41–2.66%/day), daily weight gain (2.73–2.85%/day), and daily length growth (0.0196–0.0210 cm/day). Descriptively, treatment B yielded the highest weight, while treatment A had the highest daily length growth. Water quality remained within optimal ranges (25.5°C temperature, pH 8.2–8.3, DO 4.5–4.7 mg/L, ammonia 0.00–0.01 mg/L). Bloodworms were more effective in stimulating length growth, whereas the feed combination was more efficient in increasing body weight. This study contributes to the development of alternative feed formulations and provides practical recommendations to enhance aquaculture productivity efficiently, sustainably, and in an environmentally friendly manner.

Abstract

Penelitian ini mengkaji bagaimana berbagai jenis pakan dan kedalaman berpengaruh terhadap pertumbuhan lobster pasir (Panulirus homarus). Studi dilakukan selama 60 hari dengan kerangkeng berdiameter 80 cm dan tinggi 90 cm yang diisi dengan sepuluh ekor benih lobster. Sebanyak 20% dari berat tubuh lobster diberi makan dua kali sehari. Pertumbuhan berat mutIak, Iaju pertumbuhan harian (LPH), rasio konversi pakan (FCR), mortalitas, dan efisiensi pemberian pakan (EPP) adalah semua indikator yang diamati. Pengumpulan sampel dilakukan setiap sepuluh hari untuk mengamati perkembangan, dan secara berkala dilakukan pengukuran kualitas air untuk mengukur salinitas, pH, suhu, dan oksigen terIarut. Hasil penelitian menunjukkan bahwa perlakuan C, yang dilakukan pada kedalaman 5 meter dengan pakan ikan rucah, menunjukkan peningkatan bobot mutlak 51,67 g, LPH 1,74%, FCR 6,51, dan EPP 15,42%. Hasil penelitian ini adalah bahwa jenis pakan dan kedalaman lobster berpengaruh secara signifikan terhadap pertumbuhannya, dan kualitas air yang baik juga membantu kelangsungan hidup dan pertumbuhan lobster. Untuk mengurangi stres selama molting, disarankan untuk menambah tempat persembunyian di dalam kerangkeng.

Abstract

Ikan glofish merupakan ikan hasil rekayasa genetik dengan menyisipkan gen fluoresen dari ubur-ubur yang awalnya dikembangkan untuk mendeteksi pencemaran lingkungan, khususnya polusi air. Gen ini memungkinkan ikan memancarkan cahaya khas saat terpapar senyawa kimia berbahaya. Seiring waktu, glofish lebih dikenal sebagai ikan hias karena penampilannya yang menarik. Namun, informasi mengenai pengaruh padat tebar terhadap ikan glofish masih terbatas sehingga menjadi kendala  dalam budidaya yang efisien dan berkelanjutan. Penelitian ini bertujuan untuk mengevaluasi padat tebar pada kelangsungan hidup ikan glofish. Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL), 4 perlakuan dan 3 kali ulangan dengan perlakuan A = 1 ekor/L, B = 2 ekor/L, C = 3 ekor/L dan D = 6,7 ekor/L. Parameter yang diamati meliputi kelangsungan hidup, pertumbuhan panjang dan pertumbuhan bobot ikan glofish. Data dianalisis menggunakan analisis sidik ragam One-way ANOVA di software SPSS 24. Hasil uji ANOVA data terdistribusi normal (p > 0,05) dan terdapat pengaruh nyata antar perlakuan. Perlakuan terbaik diperoleh pada perlakuan A dengan tingkat kelangsungan hidup 73,3%. Padat tebar 1 ekor/L memberikan hasil terbaik terhadap kelangsungan hidup ikan glofish tetra. Hasil penelitian ini diharapkan menjadi acuan dalam menentukan budidaya ikan glofish yang optimal dan berkelanjutan.

Abstract

This study aims to investigate the stimulatory effects of natural feed with calcium and phosphorus supplementation on growth and survival via physiological poses of hepatopancreas and intestine in sand lobster (Panulirus homarus). A trial was done with three types of natural feed of shell rich in calcium and phosphorus for lobsters weighing 80 g (initial weight), and that contained different mineral values: shrimp (Acetes), with calcium/phosphorus content (mg/mg) of 757/292, anchovy (Stolephorus sp) with 500/500, and golden apple snail (Pomacea canaliculata) with 129/60. This study was conducted from October 2023 to December 2023 at the KJA of the Faculty of Fisheries and Marine Science, Universitas Padjadjaran, located on the East Coast of Pangandaran Regency. The parameters measured were survival, growth, histological health of the hepatopancreas and the intestine of the sand lobsters, and water quality. The results showed the highest survival of lobsters in the treatment fed by shrimp at 96%, and the highest specific growth rate of lobsters was found in the anchovy diet at 1.90 0.5117%. Intestinal villus area of lobster was 1857.667 µm2; besides this, the histology of Hepato pancreas and intestine has been described descriptively. Water quality parameters in the research site varied as depth-visibility was from 3.1 m, temperatures of 27 to 29°C, dissolved oxygen was 6.4 to 8.8 mg/L, pH range was 7 to 8, and the salinity range was 34 to 35 ppt

Abstract

Indramayu Regency is located in estuarine waters, namely the North Coast of Java Island, the coast which is directly adjacent to the sea with a coastline length of 147 Km makes Indramayu Regency great potential in the field of fisheries. Mullet fish (Mugil cephalus) is a type of fish that has high economic value in the Estuarine Waters of Indramayu Regency. The purpose of the research is to measure reproductive aspects which include sex ratio, gonadal maturity level, gonadal maturity index, fecundity and egg diameter and food habits which include the largest share index and trophic level of black mullet (Mugil cephalus) caught by gill nets used by fishermen. Black mullet (Mugil cephalus) is one of several fish species that have high economic value in the Estuary Waters of Indramayu Regency. This research was conducted in January 2022 - April 2022. Fish samples were taken from the catch of fishermen using a gill net. The results showed that of the 123 mullet fish caught, the ratio of male and female mullet fish was unbalanced, namely 1: 1.8 or 44% for male mullet fish and 56% for female mullet fish. Male mullets are dominant in TKG I and TKG II while female mullets are dominant in TKG III and TKG IV. The fecundity of mullets is quite large at 11,882 - 265,108 grains, Mullet diameter ranges from 0.04 - 0.78 mm with a two-peak distribution mode indicating partial spawning. The preponderance index of mullets shows detritus and phytoplankton as the main feed, zooplankton as complementary feed, and additional feed in the form of animal parts and plant parts. The habit of eating mullets is known as omnivores because mullets eat detritus and phytoplankton as their main food.Keywords: Estuary; Food habits; Indramayu; Mugil chepalus; Reproduction
