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

This study aims to evaluate the potential for hybridisation between female koi (Cyprinus rubrofuscus) and male kapiat (Barbonymus schwanenfeldii) through artificial spawning. The study was conducted at Kampar Ornamental Fish, Kampar District, Riau Province. The method used was a Completely Randomized Design (CRD) with two treatments: P1 (koi × koi) as the control, and P2 (koi × kapiat) as the hybrid treatment, each with three replicates. The parameters observed included fecundity, fertilisation rate (FR), hatching rate (HR), absolute length growth, and survival rate (SR). The results showed that hybridisation produced promising performance in terms of FR (21.99%), HR (55.02%), and SR (41.6%). In conclusion, hybridisation between koi and kapiat fish has the potential to produce superior varieties, although attention must be paid to environmental factors such as temperature and pH

Abstract

This study aimed to evaluate the effects of different types of natural feed on the growth performance and feeding habits of green lobsters (Panulirus homarus) using Smart Lobster Culture technology in floating net cages in Pangandaran Regency. The research was conducted over a 60-day cultivation period from February to April 2025. A completely randomized design (CRD) was used with four treatments A: 100% anchovy, B: 80% anchovy, C: 100% rebon, and D: 80% rebon each with four replications. The parameters observed included length and weight growth, survival rate, length percentage per harvest (LPH), efficiency of protein production (EPP), feeding behavior, and water quality. The results showed that the 80% anchovy diet (Treatment B) produced the best outcomes, with an average length increase of 5.08 ± 0.09 cm, a weight gain of 145.13 ± 5.78 g, LPH of 2.09 ± 0.08%, survival rate of ± 98%, EPP of 13.28 ± 0.47%, and a tendency for more active nocturnal feeding behavior with a higher preference for anchovy. Sufficient feed and shelter availability effectively suppressed cannibalism. Water quality parameters remained within optimal ranges: temperature 27.6–29.3 °C, pH 8.1–8.4, salinity 34–36 ppt, and dissolved oxygen (DO) 6.10–8.30 mg/L.

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

Abstract

Tujuan penelitian ini adalah untuk mengetahui proses budidaya sistem bioflok melalui penghitungan FCR dan parameter pertumbuhan ikan lele di perairan pH rendah. Sistem budidaya ikan di bioflok telah dikenal bermanfaat bagi budidaya ikan. Apabila dalam sistem budidaya padat tebar terlalu tinggi maka dapat dihasilkan limbah (ammonia) yang tinggi pula. Selain itu, padat tebar yang tinggi juga dapat menghabiskan pakan sekitar 70% dari biaya operasional dan mempengaruhi nilai FCR (Feed Convertion Ratio). Untuk meminimalisasi kondisi tersebut dilakukan salah satu inovasi yaitu budidaya sistem bioflok. Sistem ini mampu untuk memperbaiki kualitas air dan mengurangi biaya pengeluaran pemberian pakan serta menurunkan nilai FCR (Feed Convertion Ratio). Kondisi balita stunting di Indonesia masih tinggi yaitu mencapai 30,8% yang disebabkan kekurangan protein dan kalsium. Daging ikan lele dipercaya mampu mengatasi permasalahan tersebut. Agar balita di Indonesia mendapat pemenuhan gizi untuk mengurangi stunting maka pembudidaya harus mampu memproduksi ikan lele yang tinggi. Telah dilakukan pengamatan terhadap perkembangan bobot ikan selama bulan Oktober 2023 – Desember 2023 pada kolam pH rendah berbasis bioflok di Desa Apung, Kabupaten Bulungan. Parameter yang diamati pada penelitian ini meliputi, pertumbuhan bobot mutlak, rasio konversi pakan, dan kelulushidupan, pada kondisi pH rendah (4 – 6) menggunakan budidaya sistem bioflok. Hasil pengamatan menunjukkan nilai pertumbuhan bobot mutlak tertinggi 32 gram dan terendah 3 gram, nilai Feed Convertion Ratio (FCR) atau rasio konversi pakan sebesar 0,8 Survival Rate (SR) atau kelulushidupan sebesar 96,2%.
