Abstract

Udang vannamei merupakan jenis udang telah dibudiayakan di tambak dan bahkan di perairan darat (perairan tawar). Berbagai penelitian telah dilakukan terhadap keberlangsungan hidup udang vannamei terutama kaitannya dengan salinitas, namun belum ada informasi terkait kelulushidupan udang vannamei yang dipelihara pada berbagai sumber air. Penelitian ini bertujuan untuk mengetahui kelulushidupan larva udang vannamei post larva 12 yang dipelihara pada berbagai sumber air. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Pada penelitian ini terdapat tiga perlakuan yaitu pemeliharaan larva pada air yang bersumber dari laut, sumur dan dari muara. Masing-masing perlakuan terdapat tiga kali ulangan. Setiap wadah diisi dengan air media (sesuai perlakuan) sebanyak 2 L.Larva dimasukkan ke dalam wadah setelah 15 menit dilakukan aklimatisasi. Jumlah larva pada setiap wadah adalah 50 individu (25 individu/L). Salinitas air laut adalah 19 ppt sedangkan salinitas air tawar dan air muara yang digunakan sebagai media pemeliharaan adalah 0 ppt. Pengamatan tingkat kematian dilakukan setiap 12 jam dan dilakukan selama 3 hari atau 72 jam. Hasil penelitian menunjukkan bahwa larva yang dipelihara di media air tawar mengalami kematian total (100%) setelah 12 jam, sedangkan larva yang dipelihara pada media air muara mengalami kematian total (100%) setelah 24 jam. Larva yang dipelihara di air laut tidak mengalami kematian hingga hari ke-tiga atau dapat dikatakan bahwa larva yang dipelihara di air laut memiliki tingkat kelulushidupan 100%.

Abstract

The blood clam, Tegillarca granosa (Linnaeus, 1758) is one of the economically important aquatic organisms. Therefore, information related to biometric conditions is crucial as preventive and responsive efforts to manage blood clams. This study aims to analyze the biometric condition of blood clams collected from the northern coast of Banda Aceh City. Blood-clam samples were collected from three locations, namely Alue Naga, Tibang, and Deah Raya. A total of 300 blood clams were observed. The biometric parameters included the distribution of length and weight classes, the relationship between length and weight, condition factors, ratios, and correlations between total weight, meat weight, and shell weight were measured. The results showed that the majority of blood clams found in Deah Raya were in the smaller length and weight classes (30-32 mm and 12,25-17,24 g) compared to those found in Alue Naga (33-35 mm and 17,25-22,24 g) and Tibang (42-44 mm and 22,25-27,24 g). Despite having identical growth patterns (negative allometric) and condition-factor values, the blood clams collected from Alue Naga had higher meat weight ratios than those collected from the other two locations. The correlation values between the weight of the meat and the total weight of the blood clams collected from Deah Raya tends to be lower than those of blood clams obtained from Alue Naga and Tibang, which are 0,55; 0,81; and 0,78, respectively.

Abstract

Kramat, Bedil, and Temudong (KBT) islands are watershed conservation areas located in Sumbawa Regency precisely in Labuhan Bajo Village. The main problem is the prohibition of fishing in some conservation zones, thereby reducing the area of fishing. Reduced of catchment area directly affects the decrease in catches and community income. Therefore, as an effort to overcome these problems, it is necessary to optimize the utilization of other zones in the conservation area. Sustainable fisheries zones and tourism zones are zones that have not been optimally utilized. This zones has the potential for ecotourism and seaweed cultivation, but most people do not have the knowledge and skills in the development of ecotourism and seaweed cultivation. The program aims to train and assist the community in integrating ecotourism with seaweed cultivation in sustainable fisheries zones, so that it can be an alternative livelihood for the local community. the program has outcomes that consist of: the availability of alternative livelihoods for people in conservation areas based on the integration of ecotourism and seaweed cultivation, increasing community income, and building positive community perceptions for conservation activities. The method used is counseling, training and mentoring on the development of marine ecotourism and Eucheuma cottonii seaweed cultivation in the sustainable fishing zone. The results of this activity are the development of marine ecotourism in the KBT MPA as evidenced by an increase in the number of visitors (tourists) three times more than before, the availability of alternative livelihoods of the community through boat rentals and increased knowledge and skills of the community in seaweed cultivation.

Abstract

Understanding of morphometric variation, length-weight relationship, and condition factors needed to support fishery resources management and conservation. Therefore, this study aimed to determine the morphometric variation, length-weight relationship, and condition factors of the Holocentridae family landed at the Lampulo Ocean Fishing Port, Banda Aceh. A total of 50 each of the four species of fish (Myripristis berndty, Myripristis murdjan, Sargocentron tieroides and Sargocentron caudimacullatum) were collected during April 2020. Fish samples were obtained from the catch of fishermen who landed at the Lampulo Ocean Fishing Port, Banda Aceh. The parameters analyzed included morphometric variations (12 characters), length and weight frequency distribution, length-weight relationship and condition factors. The results showed that the genus Myripristis had more distinguishing characters than the genus Sargocentron, namely 50.00% and 16.66%, respectively. Myripristis berndty and Myripristis murdjan have 5 distinguishing characters (SL, HL, CPL, HD, PFL and VFL), while Sargocentron tieroides and Sargocentron caudimacullatum only have 2 distinguishing characters (SnL and PFL). The Myripristis genus that were collected tended to more length and heavier compared to the genus Sargocentron. The four spesies of Holocentridae studied had a negative allometric growth pattern (b<3) with condition factor values ranging from 0.787 to 1.417.Pemahaman terkait variasi morfometrik, hubungan panjang bobot dan faktor kondisi sangat diperlukan dalam rangka pengelolaan dan konservasi sumberdaya perikanan.

Abstract

Oedogonium sp. is important, not only from an academic standpoint but also has great ecological significance, especially in limnology. This study examines the growth and productivity of Oedogonium sp. under different light intensity in laboratory scale. The main research includes Oedogonium sp. culture, measurement of growth (doubling time (DT) and relative growth rate (RGR)), measurement of primary productivity, and the effect of light measurement on cells through observation of histological preparations. The results showed that Oedogonium sp. on indoor culture showed negative growth (RGR of -0.054), whereas in semi-outdoor culture showed positive growth (RGR 0.046 - 0.47 g / day and DT for 14.72 - 15.09 days. Primary productivity and respiration in 1000 lux lighting cultures showed greater value than cultures in 650 lux lighting. The length of Oedogonium sp. ranged from 18.68 - 34.47 µm in dark light, 51.33 - 95.00 µm in moderate light, and 48.83 - 70.75 µm in bright light. This study showed that in indoor culture, the availability of light, temperature, pH and DO significantly affect the growth of Oedogonium sp., whereas in semi-outdoor culture, temperature, pH and DO factors was not limiting factors. The difference of light intensity influenced the growth and productivity of Oedogonium sp.

Abstract

One of the efforts of farmers to improve their production is through the cultivation of single sex populations (monosex) male. Honey is a natural ingredient that contains crysin and aromatase inhibitors that play a role in the process of mas-culinization of fish. This study aimed to determine the effect of immersion larvae of tilapia Oreochromis niloticus (L) on media containing multiple doses of sumbawa honey against sex ratio, growth and growth rate. The experimental method with a completely randomized design was used. The amount of treatment used in this study was four treatments (0 ml L-1, L-1 10 ml L-1, 20 ml L-1, and 30 ml L-1) with three replications. Each treatment consisting of 30 fish. Immersions of larvae for 12 hours. To determine the effect of a dose of honey sumbawa to all parameters, ANOVA (analysis of variance) at the level of 95% was performed. The results showed that differences in honey doses given in the immersion process did not have a significant effect on the sex ratio and growth of tilapia.
