Abstract

Cholesterol is known to play an important role in nutrition of crustacean and function as a precursor for steroids synthesis, while neurohormone of serotonin could induce ovarian maturation in crustacean. Ovarian development of adult females Scylla serrata was induced by adding cholesterol in the diet and serotonin injection. This research was designed to study the effectiveness of cholesterol supplementation and serotonin injection in ovarian development. Broodstocks were stocked in nine experimental units in three fiber tanks. The fiber tank was equipped with sands substrate and flow through seawater system. The experimental crabs were assigned into a completely randomized design with a 3 x 3 factorial arrangement. The first factor was cholesterol supplementation in the diet with 3 levels (0, 0,5 and 1,0%). The second factor was serotonin injection with 3 levels (0, 5 and 10 μg/g BW). Samples of broodstock were taken every four days to evaluate the stages of ovarian maturity and parameters were used to evaluate the ovarian maturation stage are gonad index (GI) and oocyte diameter, concentration of estradiol 17β, yolk protein concentrations, and fecundity. Results showed that female crabs supplemented with 0,5% cholesterol and a combination of cholesterol 0,5% supplementation and injection serotonin with a dose of 10 μg/g BW had better reproduction development. It is concluded that ovarian development of Scylla serrata could be improved by cholesterol supplementation and serotonin injection. Key words: Cholesterol, serotonin, ovarian development, Scylla serrata   ABSTRAK Kolesterol diketahui merupakan nutrien spesifik yang berperan dalam sisntesis hormon steroid dan mengontrol reproduksi, sementara serotonin merupakan salah satu neurohormon yang dilaporkan dapat merangsang pematangan ovari dan pemijahan pada krustase. Penelitian ini bertujuan untuk mengetahui pengaruh tingkat pemberian kolesterol yang optimal dalam pakan buatan, serta dosis penyuntikan serotonin yang efektif untuk mempercepat proses perkembangan dan pematangan ovarium induk kepiting bakau Scylla serrata. Pemeliharaan induk dilakukan dengan menggunakan tiga buah bak fiber. Bak pemeliharaan dilengkapi dengan substrat pasir dan sistim air laut mengalir. Eksperimen menggunakan rancangan acak lengkap (RAL) pola faktorial, dengan 9 satuan percobaan. Faktor pertama, suplemen kolesterol didalam pakan dengan 3 tingkat dosis (0; 0,5; dan 1%) dan faktor kedua, injeksi serotonin dengan 3 tingkat dosis (0, 5, dan 10 μg/g bobot tubuh). Pengamatan terhadap tingkat kematangan ovari dilakukan setiap 4 hari sekali. Paramater pengambilan sampel meliputi  tingkat kematangan ovari, indeks gonad dan diameter oosit, konsentrasi estradiol 17β, konsentrasi protein yolk, dan fekunditas. Hasil penelitian menunjukkan bahwa induk kepiting yang disuplementasi dengan dosis kolesterol 0,5% dan induk kepiting yang mendapat perlakuan kombinasi, suplementasi kolesterol 0,5% dan injeksi serotonin dosis 10 μg/g bobot tubuh dapat menghasilkan perkembangan ovari yang terbaik. Jadi kolesterol dan serotonin dapat digunakan untuk meningkatkan perkembangan ovari. Kata-kata kunci: Kolesterol, serotonin, perkembangan ovari, Scylla serrata

Abstract

Mud crab is one of the 12 aquaculture commodities of Ministry of Maritime Affairs and Fisheries. Control of reproduction to increase seed production through feed improvement, is one of the challenges and strategies in the mud crab aquaculture. Due to lack of knowledge about broodstock nutrition lead to producing rate of seeds still relatively low. This study aimed to obtain information on the kind of feed that has specific nutrient and plays a role in increasing the success of spawning and zoea survival. Mud crab of Scylla serrata with initial weight of 500.7±103.4 g, preferably under developed gonads were maintained in a fiber tank measuring length of 2.48 m, width 1.26 m, and a height of 60 cm which is partition sealed into 30×40×60 cm3 to put one crab. Tank was equipped with sand as a substrate as high as 15 cm and seawater system with flow rate of 1 L per six minutes and 25 cm high water. Treatments were consisted of: 1. PI (fresh meat fish of Decapterus sp. with dose of 5%), 2. PSC (fresh meat mixture of Decapterus sp. 1.8%, 3% of squid, and shrimp 1.2%), 3. PB (artificial feed dose of 10%) of BW, each treatment was repeated three times. Parameters measured were the duration of ovarian to mature, egg diameter, hatching rate, fecundity, and zoea production. Data were analyzed using ANOVA. The quality of larval measured by survival and larval fat and protein content. The results showed that crabs treated by PI and PSC showed faster to get mature compared to PB treatment (p<0.05). Hatching rate of larvae in PSC treatment was higher compared to PI and PB treatments (p<0.05). Furthermore, all treatments did not affect egg diameter, fecundity, and the number of zoea (p>0.05). In conclusion, crab which fed fresh meat (PI and PSC) could get mature earlier, and have high percentage of the larval hatching than those of fed by PB. In fact that larvae from broodstock feed of PI has survival as well as protein and fat content were higher than those of fed by PB.Keywords: spawning perform, broodstock feed, mud crab (Scylla serrata)

Abstract

Mud crab (Scylla spp.) is one of the coastal fisheries resources that has important economic value. Along with the increasing market demand for mud crabs, the development of mud crab aquaculture is widely practiced in various coastal areas in Indonesia. The availability of local resource-based feed is one of the key factors for the efficiency of aquaculture efforts and the sustainability of mangrove crab aquaculture production in the region. This study aimed to examine the effect of a combination of unripe papaya fruit and fish flesh (Decapterus sp.) with different ratios on the growth of young mud crab cultured using the floating raft method in the Tuhaha Bay waters, Tuhaha Village, East Saparua District. A total of 12 mud crab were fed a mixture of papaya and fish at 10% per total body weight per day. Treatment A (5% papaya: 5% fish flesh) and treatment B (7.5% papaya: 2.5% fish flesh) were given to six individual mud crabs each. Weight measurements were taken weekly during the one-month study period. The results showed that young mud crab fed treatment B tended to have higher absolute weight growth rate and specific growth rate compared to juvenile mud crab fed treatment A but were not statistically significantly different. This finding explains that the composition of 25%-50% unripe papaya fruit combined with fish flesh (Decapterus sp.) effectively increases the growth rate of the mud crabs.

Abstract

Aru Islands Regency, especially in Sir-Sir Sub-district, there are several villages that are famous for their high potential seaweed resources, one of which is Leiting village. Eucheuma cottonii seaweed cultivation activities had stopped due to disease attacks. At present, the community of Leiting village wants to activate seaweed cultivation activities again, therefore it is necessary to assess the condition of the waters. This study aims to determine the physical-chemical parameters of the waters and analyse the suitability of these physical-chemical parameters for E. cottonii seaweed cultivation. Collection of data directly in the field includes physical-chemical parameters of the waters. Determination of the suitability of parameters for seaweed cultivation in the longline refers to Sirajudin (2009). The level of suitability was determined based on the suitability of physical-chemical parameters of waters for fish farming (Tiskiantoro, 2006). The study results show that the physical parameters of the waters include temperature range (27.20-28.07°C), salinity (28.99-29.61 ppt), brightness (2-4 metres), depth 2-4 metres, and the current strength 0.03-0.32 m/sec. While the range of water chemistry values includes pH (7.65-8.11), DO (6.85-9.52 mg/l), nitrate (0.131-0.153 mg/litre), phosphate (0.04-0.05 mg/litre), and Chlorophyll-a (0.72-3.61 mg/litre). The physico-chemical conditions in the waters of Leiting Village are still within the range of the quality standards for the development of seaweed cultivation. The results of the calculation of the suitability of waters in Leiting village found three consecutive suitability categories, which are very suitable (S1) of 12.24 hectares; conditionally suitable (S2) of 72.81 hectares and unsuitable (S3) of 11.98 hectares. So it can be concluded that seaweed cultivation activities are very feasible in the S1 area with a carrying capacity of 61 units and a capacity of 364 units are feasible in the S2 area.
