This research was conducted from August to October 2020 in the waters of Awang Bay, Lombok Island. The main data collected in this study is puerulus settlement,while the supporting data are physical, chemical and biological parameters of the waters. Observations of the aquatic environment are carried out in-situ, namely direct measurements in the field and analysis of satellite images. The collected data were analyzed by multiple regression analysis. The results showed that the distribution of sea surface temperature and chlorophyll-a in the waters of Awang Bay and its surroundings based on satellite imagery during August to October ranged from 25-32 °C and 0.1370 - 2.3532 mg/m<sup>3</sup> respectively. Warm temperatures and chlorophyll-a are concentrated in coastal areas and are decreasing towards the offshore direction. The nine environmental parameters studied contained two parameters that significantly influenced individually on puerulus lobster settlement, namely the abundance of plankton and temperature. Meanwhile, brightness, current velocity, dissolved oxygen, salinity, pH, phosphate and nitrate had no significant effect. The significant relationship between plankton abundance and temperature and puerulus lobster settlement was due to plankton being the main food for larvae, and the sea water temperature was still relatively stable so that lobster seeds still survived and could support puerulus lobster settlement.</p> Muhammad Junaidi, Nunik Cokrowati, Nanda Diniarti, Bagus Dwi Hari Setyono, Laily Fitriani Mulyani ##submission.copyrightStatement## https://journalajfar.com/index.php/AJFAR/article/view/30457 Wed, 10 Aug 2022 00:00:00 +0000 Zooplankton Diversity of Sevsak Stream (Elazıg-TURKIYE) https://journalajfar.com/index.php/AJFAR/article/view/30458 <p>The zooplankton and its seasonal distribution of Sevsak Stream has been investigated in 2021. A total of 31 zooplankton species have been recorded in the stream. Among the zooplankton, 19 species belong to Rotifer,9 species to Cladocera and 3 species to Copepoda. In every season, zooplankton species were recorded in various abundance. Highest number of taxa was recorded in spring. In this season also, an increase occurred in the individual numbers of species. <em>Keratella cochlearis</em>, <em>Polyarthra dolichoptera</em> and <em>Cyclops vicinus</em> were the most recorded species in the stream. As in the other aquatic habitat, rotifera group was determined as the most recorded species in terms of taxa and number of individuals.</p> Serap Saler ##submission.copyrightStatement## https://journalajfar.com/index.php/AJFAR/article/view/30458 Wed, 10 Aug 2022 00:00:00 +0000 Analysis of the Decision-making Process for Purchasing of Ornamental Fish at the Bogor Ornamental Fish Marketing Depot https://journalajfar.com/index.php/AJFAR/article/view/30459 <p>Ornamental fish as a commodity of high economic value and has its own charm, makes consumers have a variety of goals and needs in purchasing ornamental fish. This study aims to analyze consumer characteristics and describe the consumer decision-making process at the Bogor Ornamental Fish Marketing Depot. The method used is survey method and sampling technique using accidental sampling. The source of data using primary and secondary data with 75 respondents. The research result showed that characteristics of the respondents who visited the most were male, age ranged from 20-25 years, undergraduate education level, type of work as a private employee, and income level of Rp 1,000,000. The results of the analysis of the purchasing decision process show that most of the consumers' motivation in buying ornamental fish as decoration, the respondent's information search comes from friends and the surrounding environment. Evaluation of alternative respondents chose the reason for buying ornamental fish because the price of ornamental fish was affordable. Purchase decisions are made unplanned, while the frequency of visits by respondents is usually uncertain and the time of visit is at the end of the month. Post-purchase behavior, respondents feel that the Bogor Ornamental Fish Marketing Depot is a clean and comfortable place, respondents are also satisfied with buying ornamental fish.</p> Asep Agus Handaka Suryana, Fitriana Dyah Rachmaningrum, Kiki Haetami, Ine Maulina ##submission.copyrightStatement## https://journalajfar.com/index.php/AJFAR/article/view/30459 Fri, 12 Aug 2022 00:00:00 +0000 Non-carcinogenic and Carcinogenic Health Risk Evaluation from Fish Contaminated with Heavy Metals https://journalajfar.com/index.php/AJFAR/article/view/30460 <p>The pollution of water bodies with heavy metals can result into the possible contamination of freshwater fish. The levels of the heavy metals Pb, Fe, Cu, Zn, Ni and Cd were investigated in fish samples (<em>Ameiurus nebulosus, Pylidictis olivaris, Tilapia zilli, Clarias gariepinus</em>) collected from Kwanar-Are dam located at Rimi local government area Katsina State, Nigeria and the health risks of the evaluated heavy metals were estimated.&nbsp; The mean concentration ranges of Pb, Fe, Cu, Zn and Cd were (0.0851-0.4919, 0.3095-0.5039, 0.0366-0.0589, 0.1066-0.3015, 0.1048-0.1417, 0.0128-0.0686 mg/kg) respectively. The risk assessment for non-carcinogenic exposure effect showed that there was no health risk associated with these elements through consumption of the fish samples to the consumer population. However the risk assessment for carcinogenic exposure effect has revealed that the incremental lifetime cancer risk (ILCR) and the cumulative lifetime cancer risks (∑ILCR) were all above the safe limit for cancer in the children and the adults population for all the fish samples evaluated. The heavy metal Ni presented the greatest cancer risk and the fish sample <em>Clarias gariepinus</em> having the highest cancer risk. There is a degree of concern for consumption of the fish samples for their potentials to contribute to the population cancer risk load.</p> A. I. Yaradua, L. Shuaibu, J. I. Bungudu, A. Nasir, A.
