Abstract

Despite the high commercial success the whiteleg shrimp industry has achieved, challenges related to water quality and disease remain major issues. One approach to address these problems is Biofloc Technology (BFT). Carbon sources have been one of the factors influencing the characteristics of BFT. Some organic carbon sources used include molasses, tapioca flour, and sago flour. This study aimed to evaluate and compare the use of molasses, tapioca flour, and sago flour as organic carbon sources in BFT. It focused on examining, their impact on floc density and the growth performance of whiteleg shrimp. The study was conducted from November to December 2023 using a completely randomized design with treatments including a control, molasses, tapioca flour, and sago flour, each with three replicates. Parameters measured included biofloc volume, weight gain, average daily growth, survival rate, and feed conversion ratio. The results showed that BFV treatments with molasses, tapioca flour, and sago flour had significant differences compared to the control group. Sago flour provided a significant increase in BFV. The growth performance of whiteleg shrimp in treatments with molasses, tapioca flour, and sago flour improved and showed significant differences compared to the control. The application of BFT using molasses, tapioca flour, and sago flour as organic carbon sources significantly enhanced the biofloc volume, growth performance, feed conversion ratio, and survival rate of whiteleg shrimp. Among the tested carbon sources, sago flour demonstrated the highest biofloc volume and the most significant improvement in shrimp growth and feed efficiency.Keywords:Biofloc technologyMolassesSago flourTapioca flourWhiteleg shrimp

Abstract

Global warming and the extensive use of chlorpyrifos pose serious threats to the hatching success, growth, and survival of Nile tilapia larvae (Oreochromis niloticus). This study aimed to evaluate the combined effect of chlorpyrifos toxicity and elevated temperatures on tilapia larvae. A completely randomized design (CRD) was used with three temperature levels (28C, 31C, and 34C) and two chlorpyrifos concentrations (0 g/L and 32 g/L), totaling six treatments with three replicates each. Parameters observed included hatching rate, daily growth rate (DGR), specific growth rate (SGR), absolute growth rate (AGR), and malformation rate.Measurements were conducted daily from the first day of hatching until the end of the larval phase (Day 8). Results showed the highest hatching rate (85.33%) was achieved at 34C without chlorpyrifos, while the lowest rate (20%) occurred at 28C with chlorpyrifos exposure on Day 2. DGR and SGR significantly decreased at 34C with chlorpyrifos exposure, reaching 0.0003 g/day and 3.73%/day, respectively, compared to 28C without chlorpyrifos (0.0011 g/day and 10.78%/day). AGR remained stable across all temperatures, showing no significant differences with or without chlorpyrifos. The malformation rate, including abnormalities such as lordosis and kyphosis, increased with higher temperatures and chlorpyrifos exposure, with the highest rate (25%) recorded at 34C with 32 g/L chlorpyrifosKeywords:ChlorpyrifosNile TilapiaHatching RateLarval Growth

Abstract

Mangrove plants have the capacity to protect coastlines and inland areas from natural disasters such as hurricanes, cyclones, and tsunamis. Mangroves are one of the most productive marine ecosystems on earth, providing unique habitat for many species, as well as important goods and services for humans. Mangroves are also a spawning ground and nursery ground for various types of marine biota. The mangrove area in the Aceh Tamiang area is currently in trouble because of the many activities such as changing the function of land as ponds, housing, infrastructure development and making charcoal kitchens, which can change the function of the mangroves. For this reason, it is necessary to carry out research with the aim of mapping the distribution of mangrove ecosystems using multi-temporal satellite imagery, classifying mangroves based on their density classes and finding out the type of mangrove that is dominant in the mangrove density. This research uses the Purposive Random Sampling method as a technique for taking several scientific considerations. This research also uses the NDVI (Normalized Difference Vegetation Index) method by categorizing 3 classes in density in the Seruway, Bendahara, Banda Mulia and Manyak Payed Subdistricts in five different periods, namely 2002, 2007, 2012, 2017 and 2022. The results obtained the highest NDVI value was in 2002 at 0.98 with an area of 2152.61 ha (16.52%) and the lowest value was in 2007 at -0.23 with an area of 474.15 ha (4.47%). The total type of mangrove found in Aceh Tamiang District is 27 types. Seruway Subdistrict found the most types of mangroves, around 23 types, and in Banda Mulia Subdistrict, the fewest types of mangroves were found, around 12 types.Keywords:Mangrove ecosystemNDVI methodMangrove densityCoastal LULCMangrove type

Abstract

Freshwater crayfish (Cherax quadricarinatus) is a valuable aquaculture commodity with relatively easy cultivation. However, low larval survival during early developmental stages remains a major challenge in its farming. This study aims to evaluate the effects of dissolved glucose and amino acid combinations on growth characteristics, molting frequency, and survival rate. The research was conducted in the Greenhouse of the Faculty of Agriculture, Animal Husbandry, and Fisheries, Universitas Muhammadiyah Parepare, using hatchery-produced crayfish larvae. Four dosage combinations were tested: A) 100 ppm glucose + 250 ppm amino acids, B) 150 ppm glucose + 200 ppm amino acids, C) 200 ppm glucose + 150 ppm amino acids, and D) 250 ppm glucose + 100 ppm amino acids, each replicated three times. The results showed that glucose and amino acid combinations significantly affected crayfish length growth. The highest absolute length growth was observed in the 250 ppm glucose + 100 ppm amino acid group. Meanwhile, the 150 ppm glucose + 200 ppm amino acid combination showed the best performance in molting frequency, number of molting crayfish, survival rate, and percentage of surviving crayfish. The optimal treatment for supporting freshwater crayfish growth and development was the 150 ppm glucose + 200 ppm amino acid combination.Keywords:Cherax quadricarinatusGlucoseamino acidsgrowth characteristicssurvival ratemolting

Abstract

The Striped Goatfish (Upeneus vittatus) is a demersal species of significant ecological and economic value, particularly for small-scale fisheries in Aceh Province. Accurate biomass estimation and species identification in hydroacoustic surveys rely heavily on precise target strength (TS) reference values. This study aimed to establish reference TS values for U. vittatus by examining the relationship between TS and fish morphology. Specimens collected from northern Aceh waters were measured for total length (TL: 17.328.3 cm) and weight (W, g). TS measurements were conducted using a single-beam echosounder (Simrad EK15) operating at 200 kHz with a pulse duration of 0.16 ms in a controlled water-tank environment. This approach enabled the assessment of TS variability across specimens with different TLs. A robust relationship between TL and weight revealed positive allometric growth (b = 3.2932, R = 0.94) in the study. Furthermore, TS analysis demonstrated a logarithmic increase with TL (R = 0.6459), in alignment with theoretical predictions. These findings contribute to more accurate biomass estimation and support sustainable management strategies for U. vittatus populations in northern Aceh, Indonesia. Future research should encompass a broader range of fish sizes and incorporate additional biological variables to refine TS prediction models further.Keywords:GoatfishAcehLWRTSMullidae
