Abstract

Coral reefs are unique ecosystems and only occur in the tropics area. Diversity, distribution, and coral growth are influenced by environmental factors. Coral colonies morphologies or coral lifeform rates vary significantly between species and between environmental factors. This study aimed to determine the variations of hard coral based on their lifeform; and assess the condition of reefs by measuring the percent cover of live coral in the coastal area of Rendani Airport. Coral cover and coral damage data gathering used a survey approach with Point Intercept Transect (PIT) method. The results showed the variations of coral lifeform in the coastal area of Rendani was relatively low, as indicated by the absence of some coral lifeforms in the study site. The most variation lifeform was found at 7m depth with five lifeforms, while the lowest was found at 3m depth with three lifeforms. The live coral cover reached 77,66% at station 1 and 75,00% at station 2, and the lowest coverage was 11,33% at station 3. The highest average of rubble at station 1 at 4.33% and dead coral with algae was found to be highest at station 3 at 8.00%.

Abstract

This study aims to determine the population density of Spirulina sp cultured on Walne media with different salinities (20‰, 25‰, 30‰, 35‰) on a laboratory scale. The method used is an experimental method using a completely randomized design. The results showed that different salinity had an effect on the cell density level of Spirulina sp for 10 days. The maximum total biomass density of Spirulina sp was 6071889.597 cells/ml at 30‰ salinity treatment, and the lowest biomass growth was 4187919.321 cells/ml at 20‰ salinity. Statistical analysis (ANOVA) showed that the difference in salinity to the density of Spirulina sp cells had a significant effect where the value (Fcount > Ftable) was at the 5% level.

Abstract

Plastic is a packaging that is widely used in various sectors of life. Plastic waste that has long been polluted in the waters will degrade into small plastic particles called microplastics. This study aims to determine the presence of microplastic content in water and sediment at Teluk Lampung Beach, Pesawaran Regency, Lampung Province. Sampling water and sediment was carried out at three different stations Tegal Island, Pasaran Island, and Sebalang Pier. There are four types of microplastics found fiber, fragment, granule and film. The water sample found the highest pollution with an average of 16 ind/m3 and in the sediment sample the highest pollution with an average of 180 ind/kg. The results FT-IR founds polyhlyene (PE), polythelyene therapthalate (PET), Polypropylene (PP), polystes (PES), dan polyethylene terephthalate (PETE).

Abstract

Ricefish Oryzias woworae is a species of ricefish endemic in the waters of Muna Island, Southeast Sulawesi. The economic potential of O. woworae as an ornamental fish has not been supported by the availability of information on its cultivation. One important aspect of the success of fish farming is knowledge of its reproduction. Spawning behavior information is very important to know. This study aims to examine the spawning behavior of rice fish O. woworae and the number of eggs per hour with different sex ratios of the broodstock. The research method uses an experimental design of parent sex ratio treatment female (♀) and male (♂) fish, namely 1♂ : 2♀ , 1♂ : 3♀, and 1♂ : 4♀. Prior to the study, the broodstock were acclimatized for seven days by feeding Artemia polar red. Observation of spawning behavior was carried out for five days. Observations were made every hour on the day of spawning. The results showed that O. woworae only spawned during the day between 06:00 and 16:00, with dominant synchronization behavior occurring in the morning which began to occur simultaneously on the third spawning day. Management that can be done regarding the phenomenon of brood fish-eating eggs is to put more spawning substrates for use by broodstock broodfish O. woworae to hide the eggs, so they are not eaten by other females during mass spawning. Another management method is to harvest eggs at the day and afternoon.

Abstract

Measured fishing policies with different technical characteristics and fishing areas in the measured fishing zone greatly affect the development of small-scale purse seine fishing businesses in the Kei Islands. The purpose of this study was to analyze a small-scale purse seine business operating in a measured fishing zone in the Kei Islands. The research method used in this study is a survey research method, respondent determination techniques based on purposive sampling. The data analysis used is descriptively qualitatively and quantitatively. The results showed that the technical aspects of purse seine vessels type two vessels are larger than type one vessel, purse seine fishing areas for type two vessels are in the measured fishing zones WPP-NRI 714 and 718, while purse seine type one vessel operates in WPP-NRI 714. The economic aspect shows that the highest income from businesses, owners, ABK fishermen and FADs is purse seine type two vessels operating in the measured fishing zone WPP-NRI 714. The financial aspect of purse seine fishing business types one and two vessels operating in the fishing zone WPP-NRI 714 and 718 measured fish are feasible to be developed. Small-scale purse seine fishing business type one and two vessels operating in the measured fishing zone WPP-NRI 714 is more effective and efficient technically, economically and financially. For management purposes, the utilization of fish resources in the restricted fishing zone in WPP-NRI 714 should only be intended for small-scale purse seines types one with a vessel capacity of < 5 GT and operating on fishing lanes 1 and 2, while purse seine type two vessels are in the industrial fishing zone at WPP-NRI 718 on lanes 2 and 3.

Abstract

Fishing using gill net has been done widely by fishermen in Southeast Maluku Regency, including in Ohoi Tuburngil waters north east Kei Besar District. Fishing activities using this type of fishing gear are still ongoing as a source of income for local community. The objective of this research were to (1) analyze the composition of the catch with a surface gill net based on the catching time and (2) compare yields and determine the best fishing time in the fishing process with surface gill net. The research methods were experimental fishing, observation and interview. The results showed that the total number of fish species caught with surface gill net during the research was 128 fish consisting of 7 fish species. The value of the diversity index (H') obtained for fishing in the morning was 1,60, at daytime was 1,15, afternoon was 1,30, and at evening was 0,92. According to the criteria for the diversity index, the value of H' less than 1 is categorized as low diversity. The results of the analysis of variance showed that te fishing time has a very significant effect on the catch number at the level of ά = 0.05. Based on the results obtained, it showed that the evening catch was significantly different from that in the morning, the daytime and the afternoon, while catch in the afternoon was significantly different from the day time and different from the morning time.

Abstract

Viral Nervous Necrosis (VNN) is a pathogen that is often found infecting cantang grouper and causing mass mortality of up to 100% in a short time. VNN is caused by a Nodavirus infection that infects the nervous and visual systems of fish. One of the prevention efforts against VNN infection in cantang grouper is to add Dunaliella salina extract which contains -carotene, nephtalene, tetradecane and phenol which acts as antiviral, anti-microbial and anti-inflammatory. The purpose of this study was to examine the potency of D. salina extract against clinical symptoms and anatomical pathology of cantang grouper after VNN infection. D. salina extract with doses of 250, 300, 350 and 400mg/kg of feed was added to commercial pelleted feed of the Stella B2 brand with a protein content of 42%. Feed was given to cantang grouper measuring 7-9 cm for 10 days of maintenance. Furthermore, the fish were challenged using VNN as much as 0.2 ml/head through the injection method. Observations of clinical symptoms and anatomical pathology were observed for 96 hours after infection. Symptoms of clinical pathology of fish infected with VNN appear to be circling, swimming horizontally, inflation of the swim bladder, discoloration of the pectoral fins to reddish, swollen lymph organs, yellowing of the liver and darkening of the body color. The compounds found in the extract of D. salina can be used to increase the immune response and reduce the number of deaths of cantang grouper infected with VNN. The addition of D. salina extract which was higher than other doses could increase the immune system so that its survival (SR) was higher as the dose increased.

Abstract

Mud crab fishing has been carried out intensively using various types of technology, so this study was conducted to analyze the catch composition, size distribution and growth pattern of mud crab using bubu and gill nets. The research was carried out from March to May 2018 in the waters of the Babo district, Teluk Bintuni Regency with a survey model for the purpose of analyzing the effectiveness of bubu and gill nets. The results showed that the catch of mud crabs amounted to 377 individu consisting of 180 individu (54,41%) caught with bubu and 157 individu (46,59%) with gill nets. The size distribution of the carapace width of mud crabs caught with bubu from 65 to 197 mm (132,34 ± 3,85 mm) and gill nets ranged from 126 to 200 mm (165,54 ± 18,53 mm). The distribution of weights caught by bubu and gill nets were 286,34-989,42 g (684,42 ± 207,78 g) and 595,35-992,25 g (865,63 ± 86,06 g) respectively. The growth patterns of mud crabs caught using bubu and gill nets were both negative allometric (b < 3). The composition of the catch was dominated by bubu fishing gear with a wider size distribution and relatively the same growth pattern.
