Abstract

The purpose of this research was to find the different  influence of corn cob (LSA) and coconut shells (LSB) liquid smokes to the changing of thiobarbituric acid (TBA) value, benzo(α)pyrene (BP), and organoleptic value of the smoked nile tilapia during storage. The result indicated that the smoked nile tilapia which used liquid smoke corn cob had higher organoleptic value than using coconut shells. The result of organoleptic 8.60 (LSAH0), 8.24 (LSBH0), 8.02 (LSAH5), 7.88 (LSBH5), 4.91 (LSAH10), 4.56 (LSBH10) and were rejected on 10 days storage. The smoked nile  Tilapia which was processed using liquid smoke of corn cob (LSA) and vacuum packed had higher organoleptic value than those which were processed by liquid smoke of coconut shells (LSB) during  the storage. The different of liquid smoked gave very significant effect to TBA value (P<0.01). The duration of storage gave very significant effect to TBA value (P<0.01). The interaction between liquid smoke and duration of storage gave very significant effect (P<0.01) at 10th, 5th days, whereas at 0 day did not give very significant effect (P>0.01). TBA value of smoked nile tilapia using liquid smoke of corn cob (LSA) higher than using liquid smoke of coconut shells (LSB) for each storage (LSAH0 : 0.76; LSBH0 : 0.74; LSAH5 : 1.02; LSBH5 : 0.95; LSAH10 : 1.42; LSBH10 : 1.32). The result on polycyclic aromatic hydrocarbons (PAHs) of smoked nile tilapia using corn cob and coconut shells liquid smoke showed that there was no benzo(α)pyrene detected.

Abstract

Studies on the utilization of dietary practical ingredients, in particular protein sources, by penaeid shrimp juveniles were reviewed in this paper.  It has been proved by a number of researchers in shrimp nutrition that diets containing a mixture of two or more protein sources are better utilized by shrimp than those containing single protein sources.  In general, evaluation of the nutritive value of a feed ingredient for growth is based on both the quantity and the quality of the protein in the ingredient.  The amino acid composition and the relative proportions of other dietary nutrients are mostly relevant to the efficiency of protein assimilation by penaeids.  Based on the essential amino acid index (EAAI) used to screen some potential protein sources for penaeid shrimp, there were found that fish meal, shrimp meal, squid meal and soybean meal were good dietary potential protein sources with EAAIs between 0.87-0.98.

Abstract

It has been long known that the most potent factor that influences prawn production was unfavorable environment due to industrial, agriculture and habitat wastes as well as improper application of good husbandry management. This research was designed to study the effect of biological filter on the growth of tiger prawn, water qualilv, and disease incidence. 7`wo sets of experiments, namely field stddy and laboratory experiment were conducted . Field survey was carrted out to collect field data on actual husbandry practices, production, water and soil quality. Laboratory experiment was aimed at evaluating the efhctiveness of biologicalfilter and disease incidence. Juvenile prawn e (j 5 gr.) at a density of 15 animals/M2; 20 animals/M2, and 25 animals/M2 were used as experimental animals. The observed parameters were field productivity, growth, survival rate, water quolitv, bacterial counts, soil quality and disease incidence. Experiments were carried in 3 replicates. Field survey showed that prawn production decreased steephr at the third production cycle as low as 627.65 kg/Ha compared to the first cycle (1893. 28 kg/lla}. Most prawn were weak, and very vulnerable to diseases. Bacterial count was more than I0Jcfii/ml. Water quality rapidly declined as prawn grew especially during the second and third cycles. Laboratory experiment with biologicalfilter in contrast demonstrated better water quality and healthier prawn,. although water quality declined slightly along with both the age and density. The growth rate was better than during field trials; among three treatments there were signdicant dyferences; the survival rate was best at density of I 5 animals/M2 but, the best estimated production was reached by density of 20 animals/M2 producing 2645 kg/Ha/cycle without any problems for around 4 cycles. Disease incidence and parasites infestation was undetected in the tank during the experiment.

Abstract

The objective of this study was to compare dried noodles made of different type of seaweeds puree and then were compared to noodle which was made without any seaweeds puree subsitution. Different seaweeds puree (E.cottoniii, G. verucossa and mixed beetween them) were subsituted in proportion of 30% in the noodles. The results showed that subsitution of seaweeds puree increased the moisture, crude fiber, ash and iodine content of dried noodles compared to noodle without seaweed puree. The moisture contents : 10.08 ± 2.02 to 13.94% ± 0.84, fat 1.26 ± 0.22 to 2.49 ± 0.81%, crude fiber 2.00 ± 0.4 to 2.25% ± 0.18 and carbohydrate contents 63.37 ± 3.8 to 68.47 % ± 1.5. Iodine concentration in dried noodle with seaweed substitution about 1.06 ± 2.80 to 1.43 ± 0.76 ug/g, protein content 11.84 ± 1.03 to 12.42 ± 0.40 and the carbohydrate content 63.37 ± 3.80 to 68.47 ± 1.59. Significantly tensile strength (p<0.05) were found between the treatments of dried noodles. Higher water absorption by the seaweed lead to softer and spongier textural intensities in the noodles. However, different pattern was observed in the protein and carbohydrate content. The subsitution of different seaweeds puree did not give any significant influence (p>0.05) only for to the taste and colour of dried noodles.

Abstract

Wave breaking is the dominant process in the dynamics of nearshore water movements resulting in sediment transport. The transformation of the subsequent particle motion from irrotational to rotational motion generates vorticity and turbulence and this affects the sediment transport. An improved understanding of the location of the breaker point and characteristics of the wave under these changing parameters is essential to our understanding of short and long-term morphological beach development. This paper reports a series of 3-dimensional physical model tests to measure longshore current data, generated by oblique wave attack, along gravel and mixed beaches with a uniform slope and a trench. The studies described in this paper aim to improve the Longuet-Higgins’s formulae which predicted the longshore current velocity at the breaking point.

Abstract

Salted fist, one of the products od processed fish, is produced by the application of high temperature so that its quality tends to decrease during storage. One of the factors contributing to quality deterioration is the chemical reaction involving lipids such as oxidation and hydrolysis. Oxidation is caused by the presence of and accelerated by other factors such as temperature. This reaction occurs easily in fatty acid omega-3, which is one of a number of unsaturated fatty acids Hydrolysis reaction is caused by lipase enzyme in fish body. Therefore, it is necessary to find an appropriate storage method to prevent lipid deterioration. This research applied low temperature to preserve salted fish. The study was aimed at investigating the influence of low temperature (4oC) as compared to ambient temperature on the stability of fatty acids omega-3 of salted mackerel fish wrapped in vacuum packing. Results showed that omega-3 content in mackerel varied with different storage temperature and period.

Abstract

A 42-day feeding experiment was conducted to study the feasibility of utilizing azolla (Azollapinnata) meal (AZM) as a replacement for soybean meal (SBM) in the diets for juvenile Penaeusmonodon. The replacement levels of azolla meal protein in the diets were 0, 25, 50, 75, and 100% of thetotal soybean meal protein. All diets were isonitrogenous at 40% crude protein. Shrimp (mean initialweight, 0.49±0.02 g) were fed three times daily ad libitum at an initial feeding allowance of 10% totalbody weight per day. A completely randomized design was used in the study and shrimp were stocked ata density of 10 animals/72 L-tank in triplicates. There were not significant differences in weight gains(1.97-2.06 g), specific growth rates (SGR 3.81-3.89%/d), feed conversion ratios (FCR 2.06-2.77),protein efficiency ratios (PER 0.89-1.24), apparent protein utilization (APU, 43.3-56.7%), and survivalrates (99.1-100%) among shrimp groups (P>0.05). Feeding preference tests showed that either soybeanmeal-based diet or azolla meal-based diet was similarly preferred (P>0.05) by shrimp with thepreference values of 51 and 40% for soybean meal-based diet and azolla meal-based diet, respectively.The results of this study suggest that azolla meal protein can replace up to 100% of the soybean mealprotein in practical diet for juvenile black tiger shrimp Penaeus monodon under laboratory conditionswithout any adverse performance. The use of azolla meal as an alternative plant protein source tosoybean meal may be able to reduce the feed costs for Penaeus monodon aquaculture.

Abstract

Pearl culture operations can be divided into three categories which are collection/hatchery production, ongrowing and pearl culture. For the hatchery, the pearl oyster industry relies on spat collection at natural production atolls where spat is abundant during the warm season and also from broodstock in the laboratory condition. After that, hatchery grown juveniles are put into the sea on the material which they settle upon. The spat are left to grow for 2 years till an average size of 90 mm. Pearl culture involves the implantation of a spherical nucleus together with a piece of mantle tissue (Saibo) from a sacrificial oyster, into the gonads. Although pearl culture is extensive with little control over weather, the use of good management methods can drastically increase productivity and result in higher profitability. Therefore, management of culture system such as site selection, settlement, feeding, stocking density and pearl culture technique is essential. For example, site selection is the most critical factor affecting pearl oyster productivity and spat collection, as the oysters spend most of their growing time exposed to water elements. Site selection must take into account important water quality parameters like temperature, salinity and turbidity. Moreover, it was identified several problems in pearl oyster culture including predation, disease and biofouling. They can result in massive loss in productivity. However, pearl industries have solution to deal with those problems. For instance, it can be done by cleaning mesh bag, biofouling organisms and pearl oyster regularly. For the future, the genetic approach like to create faster growing oysters, resistance to diseases and production of higher quality pearls has given promising results. Therefore, the productivity of pearl oyster can be improved.

Abstract

The research determined the physiological responses in Fungia sp that’s exposed to combination of copper presence and reduced salinit for 12 h. The changes of primary production rate per chlorophyll-a and respiration per surface area were used to determine the stress occur. The results showed that no significant on the respiration rate in any of treatments between treatments or compared with control. Corals exposed to 10 µg.l-1 copper to reduced salinity were unaffected and did not affect the production rate. Coppers exposed to 30 µg.l-1 copper, reduced salinity, and combination of two stressors significantly decreased the production rate of Fungia sp.
