Abstract

Flying fish yellow wing (Cheilopogon abei Parin, 1996) is one of the flying fish species that have important economic value in West Sulawesi. This study aims to examine the lengthweight relationship and condition factors of flying fish yellow wing to provide basic data for sustainable management efforts. This research was carried out from October 2021 to March 2022. A Sampling of fish was carried out in Mosso Village, Majene Regency, West Sulawesi Province. Sample analysis was carried out at the Integrated Laboratory of the Department of Fisheries, University of West Sulawesi. The total length was measured using a digital caliper with an accuracy of 0.01 mm and the bodyweight of the sample fish was measured using a digital scale with an accuracy of 0.01 g. The results of data collection obtained as many as 104 fish samples, consisting of 59 male fish and 45 female fish. The results of the analysis of the length-weight relationship of the flying fish yellow wing obtained the equation W=0,056L2,556 in the male fish, W=0.0492L2,589 in the female fish, and the combined equation W=0.0003L2.8846. Furthermore, the results of the t-test on fish with a value of b obtained a t count > t table, so that the flying fish’s yellow wing belongs to the negative allometric (minor) growth type where the increase in body length is faster than the increase in body weight. Differences in gonadal maturity, and the availability of different food every month are the main factors causing the negative allometric growth pattern of flying fish in Majene waters. Condition factor male flying fish yellow wing ranged from 0.8712 to 1.2006 with an average of 1.0015 and the female yellow wing flying fish ranged from 0.8528 to 1.1657 with an average of 1.0046. The condition factor of female fish is higher than that of male fish

Abstract

ABSTRACT: The present study aimed to determine the effect of different pH level on the density of Skeletonema costatum. A completely randomized design (CRD) consisting of four treatments with 4 replications, including pH 5, pH 6, pH 7 (Control), and pH 8 was applied. Skeletonema costatum density rate and water quality were measured for data collection. A One-Way ANOVA was performed for statiscal analysis and analyzed descriptively. The results showed that the highest Skeletonema costatum density was obtained at pH 8 (26,667 cells/ml), then pH 7 (13,333 cells/ml), pH 6 (11,000 cells/ml) and the lowest Skeletonema costatum density was found at pH 5 (10,000 cells/ml). Statistically, the pH had a significant effect on the density of Skeletonema costatum (p <0.05). this finding suggests that the optimal pH level for rearing was pH 8. ABSTRAK: Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan pH terhadap kepadatan fitoplankton Skeletonema costatum. Metode yang digunakan Rancangan Acak Lengkap (RAL) yang terdiri dari empat perlakuan yaitu pH 5, pH 6, pH 7 (Kontrol), dan pH 8. Tiap perlakuan dilakukan tiga kali pengulangan sehingga diperoleh 12 unit percobaan. Parameter yang di uji meliputi laju Kepadatan Skeletonema costatum dan kualitas air. Analisis data menggunakan one way ANOVA untuk melihat signifikasi pengaruh perlakuan terhadap Kepadatan Skeletonema costatum dan hasil uji Kepadatan Skeletonema costatum di analisis secara deskriptif. Hasil penelitian ini memunjukkan kepadatan Skeletonema costatum tertinggi diperoleh pada pH 8 (26.667 sel/ml), kemudian pH 7 (13.333 sel/ml), pH 6 (11.000 sel/ml) dan Kepadatan Skeletonema costatum terendah pada pH 5 (10.000 sel/ml). Berdasarkan uji Anova, pH memberikan pengaruh nyata terhadap Kepadatan Skeletonema costatum (p<0,05) dengan perlakuan terbaik yakni pH 8.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu pengkayaan HUFA (W-3 Highly Unsatured Fatty Acid) pada nauplius artemia terhadap perkembangan larva kepiting bakau (Scylla tranquebarica). Metode Penelitian ini didesain dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan masing-masing 3 kali ulangan sehingga dibutuhkan wadah sebanyak 12 unit dengan perlakuan: A) Nauplius artemia diperkaya dengan HUFA selama 1 jam (Kontrol), B) Nauplius Artemia diperkaya dengan HUFA selama 3 jam, C) Nauplius artemia diperkaya dengan HUFA selama 6 jam D) Nauplius Artemia diperkaya dengan HUFA selama 9 jam. Hasil penelitian menunjukkan bahwa efek perbedaan lama waktu pengkayaan HUFA pada Nauplius artemia terhadap perkembangan larva kepiting bakau (Scylla tranquebarica) tidak berpengaruh nyata (P>0,05). Jumlah larva kepting bakau yang bertahan sangat sedikit pada perlakuan lama waktu pengkayaan HUFA pada nauplius artemia. ABSTRACT The present study aimed to determine the effect of the length of time enrichment of HUFA (W-3 Highly Unsaturated Fatty Acid) in Artemia nauplius on the development of mangrove crab (Scylla tranquebarica) larvae. A completely randomized design with 4 treatments with 3 replications were applied for experimental design, with the following treatments: (A) Nauplius artemia enriched with HUFA for 1 hour; (B) Nauplius Artemia enriched with HUFA for 3 hours; (C) Nauplius artemia was enriched with HUFA for 6 hours. (D) Nauplius Artemia was enriched with HUFA for 9 hours. The results indicated that the effect of differences in the length of time for HUFA enrichment in Nauplius artemia on the development of mud crab (Scylla tranquebarica) larvae showed no significant effect (P>0.05). Only a few mangrove crab larvae survived during treatment of HUFA enrichment time in Artemia nauplius.
