Abstract

The grouper (Epinephelus sp) is a marine fish species that many people commercially cultivate, for hatchery and rearing, and showing such promising prospect. Fish intestine and growth histology are a function of internal and external conditions, namely water quality, feed quality and feed quantity. However, even though the protein content of its feed is high, the growth of the grouper, Epinephelus lanceolatus fuscogutattus is quite low. The purpose of this study was to determine the effect of simplicia papaya on  the growth of the grouper particularly, absolute weight and the protein efficiency ratio. The research was conducted using Completely Randomized Design with 5 treatments and 3 replications (A: simplicia papaya 5% application, B: simplicia papaya 3.75% application, C: simplicia papaya 2.5% application, D: simplicia papaya 1.25% application, and E: 0% simplicia papaya). The groupers were cultivated in a floating net cage in Pangandaran Regency, Indonesia. The addition of simplicia papaya at 3.75% and 55% to the grouper’s artificial feed had influenced the number of necrotic cells at 169 and 183 cells, respectively, and so were the number of goblet cells. The addition of simplicia papaya at 5%, 3.75% and 2.5% of the grouper’s artificial feed had increased the absolute weight gain by 161.36 grams, 152.19 grams, 152.09 grams, respectively. The addition of simplicia papaya at 5%, and 3.75% of the grouper’s artificial feed increased the protein efficiency ratio by 3.18% and 3.19%, respectively.

Abstract

Waste from industrial activities can be a source of pollution for the waters of Banten Bay. One source of these pollutants are heavy metals. High concentrations of heavy metals in waters can pollute the aquatic environment, endangering all organisms. Heavy metals can accumulate in aquatic environments and living organisms such as fish. The greenback mullet Planiliza subviridis (Valenciennes, 1836) is known as a fish for human consumption. Heavy metals that are contained in mullets can move to a higher trophic level within the food chain and endanger the health of humans. This study aims to analyze the accumulation of heavy metals, such as Hg, Cd, Pb, and Cu, in the flesh of greenback mullets at Bojonegara Waters of Banten Bay. The research was carried out for five months (August - October 2020 and March - April 2021). Samplings were taken from Terate River and Wadas River, which are mullet fishing areas and natural habitats of these mullets. Data analysis consisted of descriptive and quantitative analyses. The results showed that the Hg, Cd, Pb, and Cu contents were below the quality standards based on Government Regulation of the Republic of Indonesia (PP RI) No. 22 of 2021. The greenback mullets have experienced a moderate accumulation rate. The different rates of Cu metal accumulation in each month indicate a variation in catches with low to moderate accumulation rates. The water conditions in Bojonegara can still be seen as tolerable and still suitable for mullets usable for human consumption in a reasonable amount. Monitoring and evaluation activities need to be carried out periodically for the management of the aquatic environment in Bojonegara.

Abstract

Tepung ikan merupakan salah satu komponen pakan ikan yang memiliki harga tinggi, sehingga diperlukan upaya untuk mencari alternatif pengganti dari sumber alam sekitar sehingga harga pakan menjadi lebih ekonomis. Penelitian dilaksanakan di Hatchery Laboratorium Akuakultur, Fakultas Perikanan dan Ilmu Kelautan Universitas Padjadjaran, sedangkan analisis proksimat bahan pakan dan pakan uji, pembuatan tepung ikan sapu-sapu dilakukan Laboratorium Kimia dan Makanan Ternak Fakultas Peternakan Universitas Padjadjaran. Tujuan penelitian ini adalah untuk mengevaluasi penggunaan tepung ikan sapu-sapu dalam pakan buatan terhadap pertumbuhan dan kelangsungan ikan patin (Pangasius sp.) sebagai salah satu upaya alternatif penyediaan sumber protein dalam pakan ikan. Penelitian dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL), terdiri dari 5 (lima) perlakuan dan masing-masing diulang 3 (tiga) kali. Perlakuan yang diberikan adalah penambahan tepung ikan sapu-sapu dalam pakan buatan sebanyak 0%, 5%, 10%, 15% dan 20%. Parameter yang diamati pada akhir penelitian meliputi pertumbuhan mutlak, tingkat konsumsi dan kelangsungan hidup. Hasil penelitian menunjukkan bahwa penambahan tepung sapu-sapu sebesar 10% dalam pakan memberikan hasil terbaik, dimana pertumbuhan mutlak ikan patin sebesar 1.88 gram, konsumsi 10.46 gram/hari, dan sintasan sebesar 97,7%. Berdasarkan pengamatan, penggunaan tepung sapu-sapu sampai tingkat 20% dalam pakan tidak menimbulkan pengaruh negatif terhadap kelangsungan hidup ikan patin, sehingga dapat digunakan sebagai pengganti tepung ikan alternatif dalam pakan ikan.

Abstract

The purpose of this study was to determine the effect of submerged cage depth on the growth of green lobsters (Panulirus homarus) in Vietnamese-style cultivation on the East Coast of Pangandaran. The submerged cage was intended so that the lobsters are not disturbed by the situation/water quality in the upper layer of the water. The research method used a completely randomized design using 3 submerge cage depth treatments and 4 repetitions with different ones, A (2 meters); B (3.5 meters); and C (5 meters). Lobster maintenance was carried out for 40 days using a submerged cage with a diameter of 80 cm and a height of 90 cm. Each cage contains 10 lobster seeds measuring 40 g. Frequency of feeding 2 times a day. The amount of test feed given was 20% of the lobster weight each day. Measurement of water quality as supporting data was carried out at the beginning and end of the research. Sampling was done every 10 days and the observed parameters were growth rate, feed conversion ratio (FCR), and feed efficiency (FE). Lobster growth performance showed that treatment C (placement of cages at a depth of 5 meters) was the best among the others, as well as the daily growth rate (LPH) of 1.35%, feed conversion ratio (FCR) of 12.8, and feed efficiency ( EP) of 8.6%. The water quality in the submerged cage with a depth of 5 meters was DO 5.22 mg/L, the water temperature was 28 Celsius, pH was 7 and salinity was 34 ppt.
