Abstract

ABSTRACTThis study aimed to obtain the pathogenicity of isolated bacteria from maribund barramundi Lates calcarifer with black body syndrome (BBS). Moribund barramundi was collected from the Center for Mariculture Development (BBPBL), Lampung Province. Five of pathogenic bacteria were found, i.e. Pseudomonas stutzeri L01, Vibrioharveyi, Bacillus cereus, Salinococcus roseus, and Pseudomonas stutzeri L02. The bacteria were tested for LD50 to obtain two types of high virulent bacteria to be used for the pathogenicity test. P. stutzeri L01 and V. harveyi were the most virulent bacteria with a bacterial density of 107 CFU/mL. Both bacteria were used for pathogenicity test with three treatments: injection of P. stutzeri L01, V. harveyi, mix P. stutzeri L01 and V. harveyi, and phosphatebuffered saline as control. Clinical symptoms showed a blackened body, bleeding under the belly, and inactive. Mortality of fish injected with P. stutzeri L01, V. harveyi and mix P. stutzeri L01 and V. harveyi was 53.33%, 55.00%, and 58.33%, respectively. Erythrocyte and hemoglobin in all treatments were not significantly different (P>0.05). However, there was significantly different in the total leukocytes of mixed P. stutzeri and V. harveyitreatment (P<0.05). In conclusion, P. stutzeri L01, V. harveyi and mix of them resulted in black body syndrome (BBS) disease. Coinfection of P. stutzeri L01 and V. harveyi produce higher mortality than single infection.Keywords: barramundi, black body syndrome, histopathology, pathogenicityABSTRAKPenelitian ini bertujuan mendapatkan patogenisitas bakteri dari ikan kakap putih L. calcarifer yang memiliki gejala black body syndrome (BBS).

Abstract

Bireuen Regency has the potential for coastal ecosystem resources. There are two Fish Landing Sites (PPI) with very high activity, namely PPI Peudada and PPI Jangka. The high level of activity leads to concerns about pollution, one of which is the presence of lead (Pb) metal. This research aims to assess the characteristics of mangrove areas, seawater samples for heavy metals Pb, and sediments around the coastal fishing port area of Bireuen Regency. The study was conducted in 2024. Research was carried out at two sampling locations of the Fish Landing Sites (PPI), namely the Peudada Fishing Port and the Jangka Fishing Port using purposive sampling methods. At the BARISTAND (Aceh Research and Industrial Standardization Agency) laboratory, samples were analyzed using an AAS (Atomic Absorption Spectrophotometer). The Pb concentrations in seawater and sediment at first Location (Peudada) were <0.0003 mg/L and 2.60 mg/kg, respectively. At second Location (Jangka), the concentrations were <0.0003 mg/L and 1.78 mg/kg, respectively. Observational results indicate that Pb metal contamination in seawater and sediment at locations 1 and 2 is still below the threshold limit set of Ministry of Environment No. 51 in 2004 and RNO in 1981.

Abstract

Bireuen Regency, located on the eastern coast of Aceh, is rich in natural resources, particularly in marine fisheries. Among these, mantis shrimp are a notable resource, though their population dynamics remain undocumented. Currently, mantis shrimp are considered bycatch by local fishermen, with most being discarded. To address this gap, this study aimed to identify and analyze the morphology and composition of mantis shrimp in the waters of Bireuen Regency. The research was conducted from October 2024 in Gandapura District, employing purposive random sampling at three designated sites. The species identified was Harpiosquilla raphidea. Morphological measurements revealed six body segments: head length (PK), head width (LK), body length (PB), body width (LB), tail length (PE), and tail width (LE). Results indicated that mantis shrimp constituted 50% of the catch, followed by tiger shrimp (25%) and kelong shrimp (25%). The length-weight relationship of mantis shrimp showed a b-value of <3, signifying negative allometry, where growth in length outpaces growth in weight. These findings provide baseline data for further studies on mantis shrimp populations and their potential utilization in sustainable fisheries.

Abstract

This community service program aimed to empower residents of Krueng Mate Village, North Aceh, through yard-based local food security initiatives. The main issues identified were the underutilization of home yards and limited access to sustainable food sources. The program involved awareness sessions, technical horticultural training, seed distribution, planting, and growth monitoring. A participatory approach encouraged active community involvement. Results showed a plant survival rate above 85% and increased public knowledge and skills in managing yard crops. The program helped meet household food needs, reduce daily expenses, and strengthen community solidarity. The success of this initiative in Krueng Mate indicates that food security based on community empowerment can be an effective strategy to enhance socio-economic resilience. This activity is expected to be replicable in other villages to support sustainable development through local resource optimization.

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.
