Abstract

The whiteleg shrimp (Litopenaeus vannamei) is a prominent species in global aquaculture due to its resilience to environmental fluctuations and high growth potential. The success of the larval phase is critically determined by feed quality and the stability of the culture environment. This study comparatively evaluated the efficacy of various feed types on the performance of Litopenaeus vannamei postlarvae. A comparison was made between live, frozen, and preserved natural feed (Artemia sp.) and formulated pellet feed in terms of growth, survival rate, and Vibrio bacteria abundance. The results highlighted that frozen Artemia sp. (P2) was significantly superior to other treatments. Postlarvae fed frozen Artemia sp. exhibited the highest growth (length and absolute weight) and survival rate, reaching 78.67%, significantly surpassing the pellet-fed group (K1) with a survival rate of only 60.67%. Furthermore, the Vibrio bacteria abundance in the frozen Artemia sp. fed group was also relatively low compared to the pellet-fed group (13.33 CFU mL⁻¹). Although live and preserved Artemia sp. yielded better results than pellet feed, frozen Artemia sp. remains the most effective feed choice for optimizing early-stage L. vannamei aquaculture. Keywords: Artemia sp.; Feed; Litopenaeus vannamei; Postlarvae; Vibrio sp.

Abstract

This study examines the relationship between zoobenthos diversity, sediment characteristics, and mangrove density in three fishery harbors in Bireuen District: PPI Peudada, PPI Jeumpa, and PPI Jangka. Data were collected using quadrat and line transects with purposive sampling. Peudada showed the highest zoobenthos diversity (H'=0.71) with low dominance (D=0.27) and medium sand substrate. Jeumpa and Jangka were dominated by tolerant species and coarse sand. True mangrove regeneration was more developed in Jeumpa and Jangka, while Peudada was dominated by non-mangrove vegetation. There is a strong relationship between sediment type, zoobenthos diversity, and mangrove structure. Fine sediments favored benthic diversity, while coarse sediments supported mangrove growth. The findings highlight the importance of integrated coastal ecosystem management to sustain ecological functions in fishery ports. Keywords: Bireuen; Coastal Ecosystem; Mangrove; Sediment; Zoobenthos
