Abstract

The success of a culture depends on the quantity and quality of water used in fish culture without water exchange, the concentration of aquaculture waste such as ammonia (NH3) will increase very rapidly and is toxic to the cultivated organism. One of the innovations applied in fish farming is integrating plants through an aquaponics system. This study aims to determine the effect of using a settling tub in reducing ammonia waste (NH3) and growth in tilapia aquaculture using an aquaponic tidal system. The size of the initial tilapia seeds used is 3-4 cm. There are two treatments used, without settling tub (A) and addition of settling tub (B) with three replications. However, the results showed no significant differences (P>0.05) between treatments for all parameters observed. It is necessary to carry out further research on different fish and plants to see the optimization in reducing ammonia waste (NH3).

Abstract

The troll line fishery developing in the TPK Kei Kecil conservation area is a small-scale fishery consisting of 2 types, bottom and surface troll line. Both kinds of troll lines have technical differences. These technical differences will impact the type of catch and income of the troll line fishermen. This study examines the technological-economic characteristics of small-scale surface and bottom troll line fisheries in the TPK Kei Kecil conservation area. Primary and secondary data are needed, and the data is collected using a survey method with triangulation techniques. The analysis used is qualitative descriptive analysis for the technological aspect and quantitative analysis for the economic aspect. The analysis results show that the construction of surface and bottom troll line fishing technology has differences in ship construction, fishing gear, fishing methods, and different fishing seasons, as well as impacts on the types of target fish. Economically, bottom troll line fishing using a 15 HP outboard motor propulsion is more economical in the west season, and surface troll line fishing using a 15 HP outboard motor propulsion and 6.5 HP trolling is more economical in the east season; therefore, troll line fishing fisheries management needs to be carried out adaptively

Abstract

Stunting is a serious health issue that affects children's physical and mental development, with both short-term and long-term harmful impacts. This study aims to examine the influence of social aspects of women in coastal areas on stunting prevention, focusing on the role of fisheries product diversification. Data were collected through observation, interviews, and questionnaire responses from three groups of mothers: mothers of toddlers, pregnant mothers, and breastfeeding mothers. Data analysis using a quantitative approach through multiple regression analysis shows that for mothers of toddlers, variables such as parental education level, fish consumption patterns, early marriage rates, availability of health facilities, and the role of fisheries product diversification significantly impact stunting prevention. For pregnant mothers, considerable influence was found on the availability of health facilities and the role of fisheries product diversification. Breastfeeding mothers, variables like parental education level, child-rearing patterns, fish consumption patterns, and the availability of health facilities showed significant effects. The results of this study are expected to contribute to developing more effective and integrated health policies, particularly in stunting prevention in coastal communities.

Abstract

Amylolytic and proteolitic activity from thermophilic bacteria have been observed from the Way Panas hot springs, Kalianda, South Lampung. This study aims to isolate and screen amylase and protease enzyme-producing thermophilic bacteria and their potential in fisheries. A total of 8 bacterial isolates were examined from the Way Panas hot spring, Kalianda. Each was cultured on selective medium for amylase and protease production. The results showed that 4 bacterial isolates were able to hydrolyze starch (A.WP.50.1, A.WP.50.1, A.WP.50.3, and A.WP.50.4) were able hydrolyze starch and no bacterial isolates had hydrolysis activity against protein. The highest activity of amylolitic was achieved by A.WP.50.4 bacteria isolate. Based on the phenotype, biochemistry assay, and 16s rDNA sequencing, the A.WP.50.4 bacteria isolate have high similarity and identified as Bacillus cereus.

Abstract

White snapper (Lates calcarifer) is a fish that has high economic value because it has entered a large export market. The obstacle in the cultivation of white snapper is that it requires a higher protein in the threshing phase compared to larger fish to increase the growth performance of white snapper. This study aims to determine the best lysine dose for increasing the growth performance of the white snapper in the threshing phase. The research design method used was a completely randomized design (CRD) with three treatments and three replications. The treatments given were artificial feed without the addition of lysine (KPKM), artificial feed with the addition of 0,15% lysine/kg of feed (KP A), and artificial feed with the addition of lysine 0,35%/kg of feed (KP B) for 56 days. The results obtained in this study were all parameters showed that the results were not significantly different between treatments (p> 0.05) for 56 days of maintenance. This is presumed because the levels of lysine in the formulated feed and the levels of lysine absorbed by the fish in the control treatment were higher than the other treatments. Then for the survival rate, the calculation result is 100% for all treatments. Based on the results obtained, it can be concluded that there is no best lysine dose in this study

Abstract

Lack of distribution, inbreeding depression, and environmental factors were several negative impacts on tilapia fry quality. It is needed to enhance fry quality by increasing the reproduction performance of broodstocks with nutrients and hormones by using Egg stimulant® and Oodev®. This research purposed to evaluate the maturation process with Egg stimulant and Oodev application and effective doses to increase reproduction performance of female tilapia broodstocks. This research conducted within two months at Unit Pelaksana Teknis Dinas Perikanan Budidaya Air Tawar (UPTD PBAT) Wilayah Barat Tanggamus. The research design used was a complete randomized design two factors and two levels with three replications. Control treatment (K) (Egg stimulant feed 0 g/kg and Oodev injection 0 mL/kg), P1 (Egg stimulant feed 3 g/kg), P2 (Oodev injection 0,5 mL/kg), and P3 (Egg stimulant feed 3 g/kg and Oodev injection 0,5 mL/kg) The results showed that P1, P2, and P3 treatments were not significantly different to eggs diameter, gonadal maturation level, gonadal maturation index, relative fecundity, and fertilization rate. However, Egg stimulants and Oodev have functionally enhanced reproduction performances of female tilapia broodstock. It is showed by treatments have a better result than control. The effective doses of Egg stimulant, Oodev, or combination need a longer period of research to applying in tilapia.
