Abstract

Spirulina platensis is a marine microalga that has potential as a natural fish feed and is considered an absolute food supplement to combat malnutrition in some countries. Azolla microphylla is a water fern that has been cultivated, contains high protein, grows quickly and is widely found in tropical waters. This study analyzed the effect of liquid fertilizer of A.microphylla on population growth and chlorophyll content of S. platensis. A completely randomized design (CRD) was used and the treatments were A (3 mL/L), B (5 mL/L) and C (7 mL/L), D (negative control without liquid fertilizer) and E (positive control, addition of 1 ml/L Walne fertilizer). The measurement results showed that the water quality during the study was in good condition, the water temperature ranged from 28-29 C, pH (7-8) and salinity (25 - 26 ppt). The highest population density level of S. platensis (321,500 cells/mL) was recorded in treatment B. Then followed by treatment D (270,600 cells/mL), treatment C (260,000 cells/mL), treatment A (220,000 cells/mL) and treatment E (150,000 cells/mL). The highest chlorophyll content was found in treatment C of 0.362 g/L, treatment D (0.302 g/L), treatment A (0.182 g/L), treatment B (0.250 g/L), and treatment E (0.072 g/L).

Abstract

Shark is one of the fish caught and traded around Bintan Island, Indonesia. There are at least 13 species of shark and of which there are 3 species that are already in endangered status. This research was conducted from January 2 to June 30 at the Padang Coastal Marine Resources Management Center (PCMRMC), Tanjung Pinang Work Unit. The purpose of this study was to identify the species of deep shark whose population is critically endangered and endangered in the waters around Bintan Island, Riau Island Province, Indonesia. Shark identification is done by observing the shark's physical body in whole or in part. Includes color, fin shape, tooth shape, motif. A number of 3 critically endangered and endangered shark species were identified from Bintan Island waters, namely the scalloped hammerhead (Sphyrna lewini Griffith & Smith, 1834), zebra shark (Stegostoma tigrinum), and sandbar shark (Carcharhinus plumbeus). All of these sharks are still caught, consumed and traded in this area. According to the IUCN, the current population conservation status of them is critically endangered (scalloped hammerhead), and endangered (zebra shark and sandbar shark).

Abstract

Cobia fish (Rachycentron canadum) is one of the marine carnivorous fish that is relatively new and has the potential to be cultuvited. This study aims to determine the effectiveness of larval rearing and nursery cobia fish found in the Center for Marine Aquaculture (BBPBL) Lampung. Held 20 January to 19 February 2021. The mature fish were mated in a 2x2x1 m concrete tank filled with 4,000 L of water. The eggs produced were harvested using an egg collector, counted and hatched in a 0.8x0.6x0.5 m aquarium. After hatching, the larvae were moved into nursery tanks with a density of 5-7 fish/L. Larvae were reared until they were 25 days old and fed naturally with Branchionus sp, Nannochloropsis sp, and artemia. The larvae were then counted, weighed, measured, graded and their growth analyzed. The results of this study showed that not all of these cobia eggs were fertilized by male cobia sperm at the time of spawning. Spawning was carried out on January 16, 2022. Total eggs was 648,000, total fertilized eggs was 480,000 and fertilization rate was 74.04 %. The results of the initial larval count were 75,000, 17,040 were harvested with a survival rate of 22.72%. Water quality (pH, DO, temperature, salinity, nitrite and ammonia) during the research was still normal.

Abstract

Temephos is the most commonly used synthetic larvicide to control vectors of several diseases. Currently in some areas there has been resistance of larvae to temephos, so natural larvicides are needed as an alternative. Rhizophora apiculata contains flavonoid compounds that are respiratory toxins to some larvae. This research was conducted in March - Juny 2022, to determine the inhibitory of mangrove extract against mosquito larvae in brackish water. Samples were collected from the Bakar Bakau Dumai, Riau Indonesia. The experiment was setted in a single factor experimental design. Mangrove leaves are finely ground and kneaded while mixed with water and deposited for 6 minutes and filtered. This extract solution was mixed with brackish water to obtain a test medium of 500 l with a concentration of 6 (a1), 9 (a2) and 12% (a3), positive control or 1 g of abate powder (a4) and negative control or brackish water (a0). A total of 20 mosquito larvae were put into the media and their mortality was observed at 0, 15, 30, 45 and 60 minutes after introduction. The mortality of larvae were then analyzed using probit analysis to obtain LC50 (Lethal Concentration 50) and LT50 (Lethal Time 50) values. R. apiculata extract is toxic to mosquito larvae, where larval death has been seen since 15 minutes and continues until 60 minutes after introduction. At the 60th minute the mortality rate is as follows; a1 (60 %), a2 (80 %), a3 (100 %), a4 (100 %), and a0 a1 ( %). Based on the results of the above probit values ​​in the LC50 and LT50 tests on R. apiculata leaves, the LC50 value is 9,732 while the LT50 value is estimated at 21,217

Abstract

This study aimed to analyze the utilization study of Dumai Fish Landing Base facilities in Riau Province. This research was conducted in March 2023 at the Fish Landing Base (PPI) in Dumai City, Riau Province. The methods used in the study were surveys and interviews. The results showed that the fishing gear used by fishermen at PPI Dumai were gillnet, longline, sondong, and kurau net. The high percentage of utilization of dock facilities is about 545,45% and the port pool area is 139,98%, which means that the port pool area has exceeded highly utilized, while the utilization rate of the port pool depth is 87,5%, which means that it can still be utilized more optimally by fishermen. The utilization rate of the PPI Dumai auction building facility is 72,98%, which means that the auction building has exceeded being highly utilized

Abstract

Mantis shrimp as one of the foods that come from the sea and ponds is not immune from disease infection, one of which is infection by fungi. Mantis shrimp (Squilla mantis) is one of the crustaceans that has a physical shape resembling a praying mantis. This research was conducted on January– February, 2022 at the Fish Quarantine Station for Quality Control and Safety of Fishery Products (SKIPM) Pekanbaru, Riau. The research method used is the survey method. Mantis shrimp samples came from Bengkalis which were trafficked at SKIPM Pekanbaru. The results of the incubation in the first isolation stage that have been overgrown with fungi, then the purification stage is carried out. The fungus that grows is carried out in the staining stage to make it easier to observe the fungus under a microscope. Furthermore, the identification of fungi in mantis shrimp using a microscope and referring to the book Identifying Filamentous Fungi. The results showed that there were 2 types of fungi, namely Fusarium sp. and Penicillium sp

Abstract

The purpose of this study was to determine the factor of the need for supplies at sea in sondong boats and gillnets and to prove how strong the relationship between these variables is. This research was conducted in January 2022 at the UPT Fisheries Port of Riau Province using the survey method. The results showed that the factors of ship size, length of time at sea, and engine power had a strong effect on the amount of fuel carried. Based on the F-test with a confidence level of 87.1%. According to the T-test, the length of time at sea has the greatest influence, while for the application of ice, the factors of length of time at sea and catch greatly affect the amount of ice in the T-test with a confidence level (coefficient of determination) of 46.7%. According to the T-test, the length of time at sea has the greatest effect on the ice supply on the sondong ship. In gill nets, boat sizes, length of time at sea, and engine power have a strong effect on the amount of fuel carried. Based on the F test with a confidence level of 91.5%. According to the T-test, the length of time at sea has the greatest effect. Whereas in the provision of ice in gill net vessels, the length of time at sea and the catch also greatly affect the amount of ice carried with a confidence level (coefficient of determination) of 88%. According to the T-test, the length of time at sea has the greatest effect on the supply of ice in gill net boats
