Abstract

Wae Randang is one of the rivers that flows in Ngana Mbaur Village and directly empties into the sea. This river has the potential for eel population, because its location is in accordance with the natural habitat of eel fish. Therefore, it is necessary to conduct research to assess the presence of eel Anguila marmorata in Wae Randang River, especially from November to December. The purpose of this study was to determine the length, weight, and diameter of A. marmorata eels found in certain periods in the river. The research was conducted from November to December 2022, with descriptive data analysis and presented in the form of figures and tables. In the study obtained as many as 11 eels A. marmorata caught during November to December. The fish had a total length of 30-52 cm, total weight of 48-323 g, anal length 17-30 g, dorsal length 19-42 g, body diameter 6-12 g, and head diameter 5-9 cm. Based on the length and weight of the recorded eels, the fish were in the elver and yellow eel stadia. Keywords: Eel, potential, study, Wae Randang

Abstract

The research conducted over approximately 60 days at Tarus River, Mata Air Village, Kupang Regency aimed to assess the variety and abundance of eel fish, a high-value commodity in the international market. The study focused on three stations along the river, where the density of eel fish was observed: station 1 (8 individuals), station 2 (5 individuals), and station 3 (2 individuals). Using digital scales, researchers measured the total weight of the caught fish, alongside noting the types of eel fish obtained. The findings, analyzed descriptively and presented through tables and figures, revealed the prevalence of eel fish type A. marmorata during the research period, primarily in the yellow eel and elver phases with varying sizes. Morphometric measurements indicated that Anguilla marmorata specimens typically ranged in total length (35-47 cm), dorsal length (20-30 cm), anal length (15-25 cm), head diameter (5-7 cm), body diameter (7-9 cm), and total weight (170-181 grams). Additionally, water quality assessments at the research site indicated temperatures ranging from 20-27oC, with a pH of 7.5. Keywords: Identification, eel fish (Anguilla marmorata).

Abstract

Anadara granosa is one of the fisheries commodities that is abundant in various regions, especially tropical areas. The high use of blood cockles by the community in Motadikin waters is considered to result in a decline in the population of blood cockles in nature, thereby increasing population growth. This research aims to examine the abundance and morphometric features of blood cockles in Motadikin waters, Malaka Regency. This research was carried out for 1 month in Motadikin waters, Malacca Regency using the transect method. The number of transects used was 3, the distance between transects was 25 m and each transect used 6 quadrants with a size of 1x1 m and the distance between each quadrant was 5 m. The results of the research showed that the abundance of blood clams in Motadikin Waters was an average of 5-7 individuals/m2 and the average The average abundance found on substrates covered with mangroves (I) is higher than on sandy substrates alone (II). Meanwhile, morphometric measurements of blood clams in Motadikin waters are dominated by blood clams with a length range of 3.2 cm - 3.9 cm, with a shell height of 1.4 cm - 2.7 cm, an umbo height of 1.1 cm - 1.2 cm, shell thickness 2.4 cm - 2.6 cm and ligament length 2.4 cm - 2.7 cm. Keywords: Anadara granosa, abundance, morphometrics, motadikin waters.

Abstract

This research aims to determine the effect of extracts from frangipani flowers under anesthesia during dry transportation on the growth of milkfish and their survival. In the research, fish measuring 4-6 cm and weighing 4-5g were used. The test fish were fasted for 3 days to reduce metabolic activity before being transported. Before packing, a treatment solution is made according to the concentration, namely 4 mg/L, 6 mg/L, and 8 mg/L. Test fish that are placed in the treatment solution are observed for the time required during the fermentation process. Fish that have been knocked out are placed in a transportation container in the form of low-temperature sawdust and lined with gauze and ice. The test fish were then transported for 12 hours and the fish were placed back in a container containing clean aura. The number of fish that died for each treatment was recorded. The method used was a completely randomized design (CRD), where there were 3 treatments with repetition 3 times. The variables measured were the duration of the stunning process, sedative time and survival time. The research results showed that the higher the concentration of dried Plumeria acuminata extract, the higher the sedative time but the lower the stunning time. Apart from that, the results of this research also show that the higher the concentration of Plumeria acuminata extract is followed by the higher the survival rate.

Abstract

Pearl mussels are included in commodities that almost all parts of the body can be utilized. Starting from the pearls produced, pearl clam shells, and pearl clam meat have a selling value in the market. In addition, pearl mussels (Pinctada margaritifera) have a delicious taste and have a high enough protein content to become a target for public consumption. The cultivation of this type of pearl mussel is still very little, and the utilization of this type of pearl mussel still relies on nature, this certainly has the potential for a decrease in its population in nature. This study aims to determine the effect of density on the growth rate and survival of pearl mussel juveniles (Pinctada margaritifera). This study used treatment A (8 individuals/basket), treatment B (12 individuals/basket), treatment C (16 individuals/basket), treatment D (20 individuals/basket). The results of the analysis conducted showed no significant difference (P> 0.05) in the growth and survival of pearl mussels (Pinctada margaritifera). The research was conducted for 2 months in the waters of Tanah Merah Village, Kupang Regency. Keywords: Density, Pearl mussels (Pinctada margaritifera), Absolute Growth, Survival

Abstract

In an effort to carry out cultivation activities, the obstacle is the availability of seeds is not met, so it is necessary to bring in seeds from other areas. To support cultivation activities, an effective transportation method is needed, one of which is dry system transportation or without water media. By carrying out dry transportation, it can save costs, reduce fish stress, and increase the number of transportation. This study was conducted using a completely randomized design (CRD) with 3 treatments and 3 replications, with the test organism being 5-6 cm white snapper seeds. The treatments tested were different densities, namely treatment A density of 10 fish, treatment B density of 15 fish, and treatment C density of 20 fish. Fish transportation was carried out with previous fish anesthesia, using commercial clove oil anesthetic with a dose of 0.10 ml / liter of seawater. Based on observations of transportation for 1 hour of travel, treatment C was the best treatment, namely with an inductive time of 4 minutes, a duration of unconsciousness of 1 hour, and a sedative time of 18 minutes, resulting in a post-transportation survival rate of 78% and a final maintenance survival rate of 76%. The use of clove oil is effective in maintaining the survival rate after dry transportation and after the end of the research on white snapper (Lates calcarifer) seeds. Keywords: Clove oil, density, life, transportation of dry systems, white snapper
