Hilsa shad Tenualosa ilishais of the indigenous fish species and the icon of the Labuhanbatu Regency, Indonesia. Presently, a very limited study was done in this species. Hence, the purpose of this study was to analyse the distribution and growth patterns based on the length-weight relationship of Hilsa shad T. ilishaon Bilah River, Labuhanbatu District, Sumatera Utara Province, Indonesia. Sampling was carried out for 3 months starting in February-April 2019 with the exploration method. Determination of sampling locations based on information from local fishermen. Analysis of distribution data used the Morisita index and growth patterns used the Linear Allometric Model (LAM). The analysis results of Hilsa shad distribution indicated that these fish were distributed in groups/clustered with the Morisita index value of 2.211-2.314. The growth pattern of the fish was negative allometric with a value of b3. Correlation analysis showed that DO was closely related to distribution (r2=0.661), meanwhile, light penetration was closely related to growth patterns (r2=0.914). It is concluded that the distribution of Hilsa shad fish in the Bilah River was in groups or clustered, with a negative allometric growth pattern.

Malaria infection kills more than one million human every year, mainly under-5-year-old children, including in South East Asian nations. Gamma radiation given at a single dose is commonly used to create the attenuated Plasmodium parasites to get vaccine materials. However, there is no study on the infectivity of parasites after fractionated γ-radiation. This study aimed to assess the infectivity of parasites after irradiated with fractionated γ-rays in mice. A number of Plasmodium bergheithat was irradiated in two fractions of 100 and 50 Gy, 100 and 75 Gy; and 100 and 100 Gy within 5 minutes of interval time was injected intraperitoneally into 12 mice. Mice injected with unirradiated parasites (0 Gy) served as a control group. The parasitemia level of intraerythrocytic parasites in each group was observed at days post injection up to 20 days by making Giemsa stained thin blood smears and observed under the microscope. Results showed that fractionation radiation did not effectively attenuate the parasites where they still grew in blood of mice, except for 100+75 Gy. There are no significant differences among the treatment groups (p0.05). This is different from irradiation at the single dose that resulted in almost completely attenuated parasites mainly the dose of 150 Gy. This implicating that irradiation of gamma rays at a single dose is a better way to mitigate parasites than fractionation dose as the infectivity of irradiated parasites were lower compared to that of fractionated dosage.

The concentrations of heavy metals were higher in the gills compared to other organs. The mean concentration of each heavy metal were varied significantly (p0.05) depending on the species of fish. In the histological analysis of the tissues, there was vacuolation of hepatocytes, inflammation, and necrosis. In the muscle, there was a mild lesion, necrosis, inflammation, and cellular degenerations. But the level of tissue and organ degeneration is more severe in the gills. The study showed that some levels of these metals were within the permissible recommended allowed limit for human consumption. It is concluded that Makoko Lagoon water body and fishes are heavily contaminated with heavy metals.

Marine fish community is very sensitive to environmental changes. So the number of species, abundance, and biodiversity index can be used as a reference to assess the quality of the aquatic environment. The aim of this study was to describe fish biodiversity in Belitung Timur, Bangka Belitung Islands, Indonesia. Three islands were visited i.e. Pekandis Island, and Keran Island, Gosong Semut (Gosong refers to sandbar) for reef fish survey and for the economical fish study we also visited fisheries landing sites (i.e. Teluk Pering, Tanjung Batu Pulas, and Pantai Burung Mandi). The underwater visual census was used for in situ surveys of reef fish, and the fish species landed in fisheries landing site also been checked. Forty-two families of economical fish that had been landed by local fishermen were identified, and ten families of reef fish were found in reef systems of research location. A total of 10 families were recorded from three islands in Belitung Timur Regency. In addition, 42 families of commercial fish were also observed in fish landing sites from the coastline of Belitung Timur Regency, Bangka Belitung Islands.

The experiment was conducted to determine the organ weight characteristics, carcass yield and cost benefits of Kano Brown goats fed cassava root sievate and cassava leaf meal (CRSCLM) based diets as supplement to (Pennisetum purpureum) using 36 Kano Brown goats of 8 to 10 months of age.Four diets T1, T2, T3,and T4, were formulated at the levels of 0%, 20%, 40% and 60% CRSCLM respectivelyin a completely randomized design. Each animal received a designated treatment diet in the morning for 97 days. Feed offered was based on 3.5% body weight per day; the animals in addition were fed a kg wilted chopped P. purpureum later in the day as basal diet to enhance rumination and fine chewing. Results on carcass indices showed significant (p<0.05) response on live weight at slaughter, empty carcass weight, warm carcass weight, dressing percentage, shoulder, leg, loin, end and shank with T4having relatively best results. The dressing percentage was numerically (49.59%) best at T4. On the offal weights, head and full guts were significantly (p<0.05) improved for T4and T1goats. The organ characteristic proved the safety of using CRSCLM through the significantly (p<0.05) lower organ weights at T4goats. Cost per kg feed, feed cost/weight gainand cost/benefit ratio were positively influenced (p<0.05) at T4with expected income of 4.79 / 1 invested. It could therefore be concluded that Kano Brown goats fed 60% CRSCLM had the best carcass and organ yields at a reduced feed cost.

The aim of these study was to examine the effect of the replacement fish meal with chicken feather meal (CFM) for eel Anguilla bicolor larvae. The study was conducted at the Laboratory of Ichthyology, Faculty of Marine and Fisheries of Syiah Kuala University on September to October 2017. The Complete Randomized Design (CRD) with 7 treatments and 4 replications were used in this study. The tested dosage of CFM were of 0% CFM (control), 10% CFM, 20% CFM, 30% CFM, 40% CFM, 50% CFM and 60% CFM, where each treatment were contained of protein 32.26% (0% CFM), 33.09% (10% CFM), 36.20% (20% CFM), 39.10% (30% CFM), 41.22% (40% CFM), 45.43 ( 50% CFM) and 40.02% (60% CFM). The experimental fish were stocked in the plastic container at the stocking density of 15 fish container-1 and fed the experimental diets at the feeding level of 10% body weight a day for 60 days. The results showed that the application of CFM in the diet was not given a significant effect on the weight gain, daily weight gain, specific growth rate (P>0.05). In addition, the fish fed on CFM did not show growth rate even reduces the body weight of the experimental fish. It is concluded that the application of the CFM in diet gave the negative effect on the growth performance of the eel larvae.

West Pasaman Regency in West Sumatra Province is recently established as an administrative area on 2003, segregated from Pasaman Regency where it was previously affiliated. This regency has been planning to support its structural developments using its main income generated from agricultural sector, which involve vast plantation area for oil-palm and other agricultural products. With the variety of its topography spans from some offshore islands up to 2,912 m mountain area, it is interesting to understand the importance value of this area from the perspective of one of its natural biodiversity: avifuna. Here in this paper, we use Genetic Heat Index (GHI) concept based on avian diversity and their conservation status to compare the significance value among four prominent landscapes in this regency, which include Mount Talamau and Laut Tinggal Lake (mountainous area), Tongar River (lowland-to-hilly riparian agricultural area) and Panjang Island (an offshore island). Despite the difference and similarity of bird species recorded in each site, Panjang Island has comparable GHI value with Tongar River, Mount Talamau and Laut Tinggal Lake (consecutively 4.20, 4.03, 4.14, 4.26). This result implies to the uniqueness of bird species living in each site along with its habitat typicality which also helps in contributing to their GHI value. Therefore, giving attention to this GHI concept while accommodate it into development plan will help in supporting more environmentally-sound development process.
