Abstract

The correlation between diatoms and environmental factor were studied in Akkeshi-ko estuary, easthern part of Hokkaido, Japan. This studied were aimed to clarify whether the dynamic and distribution pattern can be made by correlating for environmental variation and diatoms assemblages in an estuarine system. During this research, there are  positive correlations between pelagic diatom abundance in water column (PDWC), depth and salinity (r = 0.623 and r = 0.652; respectively). There are positive relationship between nitrite + nitrate and the abundance of diatom on the surface sediment. Seasonal variation of the relationship between abundance of diatoms assemblages and ammonia, nitrite+nitrate and phosphate showed occurs in most stations, the high abundance of benthic and pelagic diatoms in summer followed by the increasing of ammonia, nitrite and nitrate and phosphate.

Abstract

Zooxanthellae (Symbiodinium sp) from the giant clams, Tridacna maxima, were monitored for their responses to ammonium and phosphate addition in the field. Nutrient was added into ponded microatolls at every low tide using Nutrient Dispersal units (NUDs) moored outside the atolls to reach final concentrations of 10 µm for ammonium and 2µm of phosphate. Transmission electron micrograph showed that zooxanthellae size (as the maximum diameter) from nitrogen-treated clams was significantly than those from other treatments (P<0.05). However, the cross sectional area of the nucleus was not significantly affected by the treatment smaller (P>0.05). The results suggests that the condition of zooxanthellae, such as the size of zooxanthellae from giant clams is influenced by relatively small changes in the concentration of nitrogen in the water column.

Abstract

Study on the distribution of benthic foraminifera in Gili Trawangan, Gili Meno and Gili Air Lombok Island was held during November 28th – December 5th, 2008. Agglutinated foraminifera were given special attention since there have been so few records on the occurrence of this group from Indonesia. The aims of the study were to have general indication about the type and abundance of agglutinated foraminifera found in Lombok. From the 4 stations studied in each Gili, 6 species were observed at Gili Trawangan and Gili Meno, and 7 species in Gili Air. The stations which are located close to the bay normally have more individuals than ones away from it especially Ammobaculites agglutinans and Haplophragmoides canariensis.

Abstract

Milkfish brackishwater pond (tambak bandeng) in “Sumbersari” can be divided into three types: (a) fry pond; (b) brackishwater pond type 1; and (c) brackishwater pond type 2. Milkfish brackishwater pond cultivation is profitable, especially when the area is large. The idea of cultivating giant tiger shrimp (udang bago) in the brackishwater pond by using a mixed (campuran) method appears to generate considerable additional income for those who practiced it.

Abstract

Growth rates (linear skeletal extension) and the timing of skeletal band formation were measured in 15 speciments of the massive coral. Porities lutea at three locations on the north coast of Central Java. The result of skeletal X-rayed indicate that timing of the high density (HD) and low density (LD) bands is synchronous at three locations. A one year growth is characterized by three HD bands, one of which is usually wider. Comparisons of the skeletal extention rates (X-ray radiography) indicate that the growth rates of P.lutea are statistically lower at the Menjangan Kecil island when compared to Bandengan Bay (p<0.01) and Panjang island (p< 0.05).

Abstract

The mesh selectivity of monofilament encircling gillnet for Oxeye scad (Cuvier,1833). Selar boops, was investigated using multi-panel of six different nets with mesh size of 1.50”, 1.75” and 2.00” (hang-in ratios 35% and 65% for each mesh size). Experimental fishing operation was carried out in the coastal area of Waai (Ambon Island) between September to November 2009. Probability of captured of oxeyescad was estimated using Holt’s method. Estimated optimum selectivity lengths for nets with 35% hang-in ratio were 14.33 cm for 1.50” mesh size, 16.74 cm for 1.75” mesh size and 19.11cm for 2.00” mesh size. Net with 65% hang-in ratio showed slightly larger optimum selectivity lengths (14.46 cm for 1.50” mesh size and 16.87 cm for 1.75” mesh size) then the other one.

Abstract

Introduction : Smoking of fish has changed its function nowadays from just the preservative task to flavoring and coloring. The method of smoking has also been developed from traditional, which had used a simple technology to the modern method. In recent years, preparation of liquid smoke manufactured from certain varieties of wood pyrolysates have been successfully used as a substitute for the traditional smoking in a kiln. Material and methods : The objective of this study was to compare the effect of cold smoking of mackerel fish on the proximate composition, water activity, salt content and microbial aspect of smoked fish treated using oak sawdust and liquid smoke either salted or un-salted. Sensory analysis was carried out by using score sheet organoleptic and hedonic test. Identification of pathogenic bacteria was done by API-20 E method. Factorial design was administered to compare the effect of traditional and liquid smoke method to brined and unbrined smoked fish. Results and Discussion : The content of protein, lipid, water activity and salt of the two products were not significantly different (p>0.05). This means that the quality between two products were similar. Only moisture content of the products were very significantly different (p>0.01) caused by the phenomenon of osmosis between moisture of fish and brine. Study of liquid smoke treatment was found that liquid smoke was easier compared to oak sawdust smoke. It was also found that smoking reduces the number of colonies of bacteria. The number of colonies were about 1x103/g – 5x103/g after 2 day storage for unbrined smoked fish, while in brined smoked fish, no colonies were found after 3 day storage. Pseudomonas sp were present in both raw mackerel and the unbrined smoked fish sample, but were absent in the brined smoked fish.

Abstract

Blue crab (Portunus pelagicus) is a potential marine crustacean’s commodity. The increase demand both local and international market of the blue crab result in the culture development of this species. The larval stage of blue crab, especially at zoea IV to megalopa, plays an important rule on the successful of the production of marketable size under culture condition.Low survival rate of zoea IV to megalopa stage mostly due to their photo taxis behavior, thus, they are trapped at the water surface. Management of water flow rate on the zoea IV holding tank may be able to reduce their mortality rate and can reach megalopa stage successfully. The water flow rate management would keep the zoea in the suspension as well as improving the water quality, i.e. increases the dissolved oxygen in the water.This investigation was done to find out the effects of different water flow rates on the survival rate of blue crab (Portunus pelagicus) zoea IV stage. The tested animal was blue crab at zoea IV stage which undergoes an investigation up to megalopa stage. An experimental method with a Completely Randomized Design was applied. The 5 (five) treatments of different water flow rates were used, i.e.: A (0,25 l/minute), B (0,5 l/minute), C (0,75 l/minute), D (1,0 l/minute), E (0,0 l/minute). Each treatment was replicated three times.The results shows that different water flow rates gave a highly significant difference (P<0,01) on the survival rate of blue crab zoea IV - megaloga stage. The highest survival rate at the end of the experiment (at megalopa stage) was at treatment C (0,75 l/minute): 30,44%

Abstract

Fish crackers are locally known as “kerupuk ikan”. The quality of fish crackers depends on the thickness of the slice before frying, the percentage of linear expansion, and some other factors. So far, there was not any standard value of the thickness and the percentage of the linear expansion of good quality fish crackers in Indonesia yet. The objectives of this study were to gain some data on the thickness and the percentage of linear expansion of fish crackers and to compare the data with the estimated ideal value based on the reference data. Ten cottage industries in Jepara district chosen based on the proportional stratified randomized sampling method. The first grade fish crackers (according to the processor) were obtained as the samples from each of the cottage industries. Ten fish crackers of each sample were evaluated. The results indicated that the fish cracker samples were circular, the thickness varied from 1.0 to 3.85 mm. The average thickness of the samples was 2.77 mm which significantly thicker (p<0.01) than the estimated ideal thickness (1.50 mm). The percentage of linear expansion of the samples varied from 54.48 to 134.58 %

Abstract

Intertidal zone in reef flat is the extreme condition for many species of corals. Periodical tides, wave action and sedimentation become the main challenging factors which usually avoided by most of coral species. However, Montipora digitata is the species that found abundant in these conditions. Having relatively small and short-lived colony, forced this species to find the strategy to survive and maintain the energy efficiently. Understanding biology and life history of M. digitata in the coral reefs is the key to understanding how this species can adapt to the extreme conditions. The biology and life history of this study focused on the population size structure, reproduction, competitive interactions, investment repair and maintain and types of selection. M. digitata leaded to productivity as a strategy to cope with any extreme condition. This pattern relatively matched with r-and S-R selection.
