Abstract

The demand for Gracillaria commodities continues to increase for food, medicines, and beauty ingredients. These conditions encourage the cultivation of this commodity continues to proliferate. Because of that, availability of Gracillaria sp seeds is available both in quantity and quality. One effort that can be done in handling the Gracillaria sp spores through environmental engineering. One such factor is fisheries salinity. The difference in salinity supports the increase in Gracillaria spores so that it affects spore growth. The aim of the study was to study the growth of Gracillaria spores cultured on different salinity media. The method used is a laboratory experiment method with a completely randomized trial design (CRD) with forty salinity preparations (23 ppt, 26 ppt, 29 ppt, and 32 ppt) and is repeated three times. The resulting data were then analyzed by analysis of variance. The results showed the highest spore growth at 23 ppt salinity with the number of spores (560.9 Ind / cm2), then 26 ppt salinity (438.8 Ind / cm2), then 32 ppt salinity (429.9 Ind / cm2) and low in salinity 29 with the number of spores (277.8 Ind / cm2). Fingerprint analysis showed that each evaluation results were not significantly different.

Abstract

Teri (Stolephorus spp) is the mainly catched of boat life nets in Bodinga Bay, West Halmahera district. The life of teri like other small pelagic fish was needed seas parameter as well as Its live needed. The aims of this study are to know the dynamic of sea’s parameter affected to boat liftnets catched in Dodinga Bay. The data of water’s parameters like sea surface temperature, salinity, water brightness, current velocity, wind speed and teri’s catches are collected by in situ way. Data analysis by using descriptic and statistic method to explain the connection between the factors with multiple linear regression method. The result of f test showing that all water’s parameters is together had have real impact on fish catches with fcount is 9.058 and significant values is less than 0.004 while the t test show that in individual parameter only wind speeds are had have real impact on teri catches with t test value is-3.010 at significant value is 0.005 (α= ( 0.05 ). The regression equation formed to explain the wind speed and anchovies catch him are = 526.666 - 72.513 X1 + e. Furthermore get also that the optimal of teri (Stolephorus spp) catches at Dodinga Bay was occurs on range of sea surface temperature are 24 – 28oC, salinitas of 25 - 30 ppt, wind speed of 0 - 2,5 m/s, current velocity are 0,1 - 0,7 m/s and the brightness of waters are 8-11 meters.

Abstract

Gastropods plays an important role in the food chain on seagrass ecosystem and its existence are depend on the physical-chemical factors in the seagrass ecosystem. This study aims to determine the density and diversity of gastropods associated in seagrass habitat in Nusi and Gersen coastal waters. The measurement results of some physical-chemical waters variables, are still quite good for the life of gastropods. Species composition of gastropod in Nusi at higher than at the Gersen, but instead of individual density in Gersen more higher than Nusi. Diversity index of gastropods at Nusi station is higher (3,757) than Gersen (3.053), on the contrary the eveness and dominance index are higher at Gersen station than Nusi station. Community similarity index by species is low between the two stations, which indicates that the species of gastropods at both stations is quite different. The influence of human activity and higher utilizatin of gastropods in Nusi has lowered the density of gastropods in seagrass habitat, so it needs awareness efforts on the importance of gastropods and the seagrass habitat for coastal ecosystem.

Abstract

Betta fish is one of the excellent ornamental fish because it has high economic value. Betta fish that have economic value are male betta fish because it has a beautiful shape. To increase male fish production, steps can be done by masculinization. This study aims to determine the effect of celery extract on the percentage of male betta fish by masculinization. This study uses a completely randomized design (CRD) with 6 treatments and 3 replications. The treatment in this study was 7-day-old betta fish larvae soaked in celery extract media with different concentrations for 8 hours. The treatment is the addition of celery extract as much as 5 mg / L (P1), 10 mg / L (P2), 20 mg / L (P3), 40 mg / L (P4), 80 mg / L (P5) and without the addition of celery extract as a control (P0). Based on phytochemical testing, celery ethanol extract contains steroids, flavonoids, tannins, and phenols. The results showed that the addition of celery extract with different concentrations had a significant effect on the percentage of male betta fish, but there was no significant effect on survival rates.

Abstract

The decrease in water quality is caused by the presence of pollutants in the form of organic and inorganic components. Inorganic components, including heavy metals, one of which is iron (Fe). Adsorption is one of the technologies that can be used to absorb heavy metals where the adsorbent used in this study is a shell of a shell (Telescopium telescopium) to absorb iron (Fe2+). This research aims to utilize the waste of the mussel shells (Telescopium telescopium) as an adsorbent for heavy metal iron (Fe2+). The study was divided into three stages, namely the adsorbent surface characterization, determining the optimum time and determining the adsorption capacity. All stages of the study were carried out on adsorbents that were not activated and NaOH. The results showed the largest pore size after activation was 1,398 µm, while the adsorbent before activation, the largest pore size was 844.8 nm. The surface acidity of the adsorbent before activation is 5.28 mmol / g and after activation has a value of 6.74 mmol / g. The optimum time of absorption of ferrous metal ions (Fe2+) before and after activation is 60 and 30 minutes. The adsorption capacity of the adsorbents before and after activation was 11,07899 mg / g and 459,3038 mg / g, respectively. It was concluded that the shell of a temberungun shell (Telescopium telescopium) can be used as an adsorbent for heavy metal ions (Fe2+)

Abstract

Ponelo Islands is an important area to be developed with the economic potential of fisheries and marine resources. This research was conducted in May-September 2019 aimed to find out Ecological Parameters as the Basis of Bivalvia Management in Seagrass Ecosystems. The sampling method is done by using the method used in determining the observation point is the linear quadratic transect method with sampling bivalves determined intentionally with a systematic perpendicular direction using a transect measuring 1x1 m. All bivalves contained in transects / quadrants are counted and identified. The sampling locations were divided into 4 (four) stations, namely Station I (Otiola Village), Station II (Ponelo Village), Station III (Malambe Village), and Station IV (Tihengo Village). Observations at the study site found several types of seagrass ecosystems including Enhalus acoroides, Halodule pinifolia, Thalassia hemprichii, and Cymodocea raotundata. Furthermore, 8 (eight) types of bivalves were found which were divided into 4 (four) stations in Ponelo Islands, namely Isognomon isognomum, Pinna muricata, Semele crenulata, Tellina virgata, Trachycardium subrugosum, Spondylus tenellus, Tapes sulcarius, Anadara pilula. The highest abundance index value is Tellina virgata found in Otiola Village with a value of 77.78%. The dominance index value for the highest is in Ponelo Village with a value of 0.88 in the high category. diversity index (D') with a value of 0.63 found in the medium category Malambe village. Keywords: Bivalvia, Seagrass, Abundance, Dominance, Diversity
