Abstract

Tujuan penelitian ini adalah untuk mengetahui tingkah laku induk lobster air tawar pada saat proses perkawinan, pengeraman dan pemeliharaan telur, Penelitian ini juga melakukan observasi terhadap tahapan perkembangan larva yang dilihat melalui mikroskop. Metode yang dilakukan dalam penelitian ini adalah metode eksperimental yaitu untuk melihat tingkah laku induk betina selama proses pengeraman telur dan perkembangan larva pada lobster air tawar. Parameter uji dilakukan selama pemeliharaan induk dan pengeraman telur menetas. Hasil pengamatan menunjukkan bahwa tingkah laku induk selama proses pengeraman telur terlihat mulai dari 15 hari setelah induk melakukan perkawinan. Proses pemijahan akan terjadi pada malam hari atau menjelang pagi hari. Selama proses pengeraman yang terjadi selama lebih kurang 35 hari, telur lobster mengalami beberapa kali pembelahan dan perkembangan telur itu terlihat dengan adanya perubahan warna telur. Pada tahap perkembangan larva, bagian larva yang di amati adalah pada bagian yang di mulai dengan tumbuh atau terjadi penambahan bulu-bulu halus, umbai-umbai (setae), bintik hitam pada cangkang larva, serta bentuk perubahan pada selubung kepala.The purpose of this study was to observe the behavior of freshwater lobster broodstock during the process of mating, incubation and egg nursering. This research also observed the development stages of larvae through microscope. The method used in this research was experimental that was to observed the behavior of freshwater lobster broodstock during the process of egg incubation and larval development. The tested parameters during the lobster broodstock nursering phase and egg nursering until they hatched. The results showed that the behavior of the lobster broodstock during the process of egg nursering seen starting from 15 days after the broodstock mating. Spawning process will occur at night or before the morning. During the incubating process that lasted for approximately 35 days, the lobster eggs experienced several cleavages and the development of the egg was noticeable by the change of egg color. At the developmental stage of the larvae, the larval part observed is on the part that begins with growing or occurring the addition of fine hairs, the tassels (setae), the black spots on the larval shell, and the shape of the change in the head sheath.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penurunan salinitas terhadap laju konsumsi oksigen dan pertumbuhan ikan kerapu lumpur (E. tauvina). Penelitian ini dilaksanakan pada tanggal 22 April sampai 22 Mei 2015 di Laboratorium Hatchery dan Teknologi Perikanan Program Studi Budidaya Perairan Fakultas Pertanian Universitas Malikussaleh. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan lima perlakuan tiga ulangan dan dilanjutkan dengan Tukey jika terdapat perbedaan. Perlakuan yang diberikan yaitu : perlakuan A (27 ppt), B (24 ppt), C (21 ppt), D (18 ppt) dan E (15 ppt). Parameter yang diamati adalah laju konsumsi oksigen, pertambahan bobot, pertambahan panjang dan kelangsungan hidup. Hasil penelitian menunjukkan bahwa konsumsi oksigen tertinggi terdapat pada pelakuan  E (15 ppt) yaitu 0,987±0,085 mgO2/gr/jam dan terendah pada perlakuan A (27 ppt) yaitu 0,612±0,033 mgO2/gr/jam. Pertambahan bobot, panjang dan kelangsungan hidup tertinggi terdapat pada perlakuan B (24 ppt) yaitu masing-masing sebesar 1,231±0,153 gram, 0,970±0,083 cm dan 90,476 %. Selama penelitian ini suhu bekisar antara 26,9 - 29 oC, pH 6,8 - 8,2 dan DO 6,8 - 8,1 mg/ L.The purpose of this study was to determine the effect of salinity reduction in the rate of oxygen consumption and growth grouper (E. tauvina). The research was conducted on April 22 to May 22, 2015. The research was conducted at the Laboratory of Aquatic Hatchery and Technology, Department of Aquaculture Faculty of Agriculture, University Malikussaleh. The study design used was completely randomized design (CRD) with three replication and five treatments followed by Tukey if there is a difference. The treatments were as follow: treatment A (27 ppt), B (24 ppt), C (21 ppt), D (18 ppt) and E (15 ppt). Parameters measured were oxygen consumption rate, weight gain, length and survival rate. The results showed that oxygen consumption is highest in the carrying out of  E (15 ppt) is 0,987±0,085 mgO2/gr/h and the lowest in treatment A (27 ppt) is 0,612±0,033 mgO2/gr/h. Weight gain, length and survival rate is highest in treatment B (24 ppt) are respectively 1,231±0,153 gr, 0,970±0,083 cm and 90,476 %. During this study the temperature ranged between 26,9 - 29 oC, pH 6,8-8,2 and DO 6,8-8,1 mg/L.

Abstract

This research was conducted from November 2018 until January 2019 which was held at the UPTD Conservation and Supervision of Marine Resources and Fisheries in West Sumatera, Pariaman City.  The aim of the research is to know hatchling hawksbill sea turtle eggs based on nest depth. The method used in this study is a nonfactorial randomized block design (RBD) consisting of 3 treatments and 3 replications. The treatments used were treatment A (with a depth of 30 cm incubation nest), treatment B (with a depth of incubation nest 40 cm), and Treatment C (with a depth of incubation nest 50 cm). The results of this study showed that hatching hawksbill eggs hatched very significantly, the best hatching percentage was in treatment A (30cm) with 78% hatching at 6:00 a.m. with hatching temperature range of 24-28oC, hatching pH of 6,6-6,8 and medium sized incubation sand with a size of 0.150 mm with a weight reaching 461 grams.Keywords: Hatching percentage, Hawksbill turtle, pH, Temperature
