Abstract

Conventional fish cultivation system for nilem fish which is currently mostly done with high density of stocking in order to produce high production as well. This will of course have an impact on the availability of dissolved oxygen in aquaculture ponds that will result in decreased production. The use of high oxy aeration stone can increase the dissolved oxygen level in the conventional fish farming cultivation system so that the productivity of fish nilem will increase also with the reduction of mortality rate of the nilem fish. This study aims to determine the extent of the effect of adding high oxy aeration rock to increase dissolved oxygen levels that can support the success and productivity in conventional fish farming system nilem. The research was conducted in the Physiology Laboratory of Animal Water of FPIK Unpad with experimental method of Completely Random Design with three treatments: fish density of 100, 200 and 300 head / m2 and four replications. The results obtained 200 treatment / m2 gives the best results shown from the growth rate of daily weight and the highest survival during the study of 2.7% and 75.4%.

Abstract

Fishing activity by catching gill nets by Pangandaran fishermen is using traditional methods inherited by ancestors especially in determining fishing ground such as seeing the color of water surface, small ripple, fish jump, the presence of foam, and see the existence of birds. Such activities make fishing activities less than optimal because the level of uncertainty is high and will impact on high operational costs such as the use of fuel wasted and trip time becomes longer. Knowledge of fishing zones is essential for fishing activities because by knowing potential fishing areas will result optimal catch and reduced effort. Information about potential fishing areas can be obtained through analysis of the distribution of a-chlorophyll in water. The research was doing from October to November 2017. The research used survey method with 7 experimental fishing activities in Pangandaran Waters. From the results of this activity can known that category distribution of fishing ground catchment area in Pangandaran spread from medium to potential category.

Abstract

The existence of the provisions of the Ministry of Marine Affairs and Fisheries that the capture and / or expenditure of crabs (Scylla spp.) with the provisions of the size of the carap above 15 (fifteen) cm or weight above 200 (two hundred) grams per tail becomes a challenge in the soft carapas (soca) crab business that generally using crabs with an average weight below 150 grams. This study aims to determine the success rate of moulting and survival rate crab (Scylla serrata Forskal) with different salinity treatment using crabs weighing above 200 gr. This study used Completely Randomized Design with 5 (five) treatments and used 3 (three) replications, analysis of variance (ANOVA) at 95% confidence level was used to analyzing the data obtained. If there was a significant difference (P <0.05) then proceed with LSD test (Least Significant Differences) with 95% confidence level. The results of this research showed that the highest moulting success rate was obtained from the treatment with salinity of 10 ppt. While the highest survival rate (SR) was obtained from the treatment with salinity 30 ppt.

Abstract

This study aims to determine the exact combination of time and temperature of sterilization to the proximate content of canned milkfish. Where the time combination used are 60 minutes, 75 minutes, and 90 minutes. Combination of temperature used are 110OC, 115 OC, and 120 OC. This research was conducted from Januari – Juni 2017 in two locations, namely in the Workshop Teaching Factory SUPM Bone dan BPPMHP Makassar. Sampling taken from canned milkfish randomly in each treatment. The data were analyzed by using ANOVA statistical analysis and next the significant parameter were tested using Tuckey and then explained by using table. The research results that the combination of temperature and time of sterilization had a significant effect on the quality of canned milkfish. Where temperature treatment 110 OC and time of 75 minutes has the best proximate content (best nutrition).

Abstract

The purpose of this study was to determine the selectivity and level of environmental friendliness of mini bottom trawl in Pangandaran District. This research conducted on May-October 2017. Primary data obtained from purposive sampling either by interview or observation Selectivity indicator used was selectivity of catch species and size. Environmental friendly fishing was evaluated based on the FAO criteria. The result showed that catch rate of mini bottom trawl was 26.45 kg/hour. The main catch of mini bottom trawl in Pangandaran District was Trachypenaeus asper amount of 39,5% while by catch was Acetes sp¸ Oiolithes ruber, Trichiurus lepturus, and others catch with amount 60,40%. Catch size of mini bottom trawl main catch was ranged 4 cm - 9.90 cm. The main catch was 39,00% was more than size capture and under size capture was 61.00%. Catch utilization of this fishing gear was 93%. The result evaluation of environmental friendliness based on catch selectivity was 6 point which mean ‘less environmentally’ friendly while FAO criteria showed 18 point which mean ‘not environmentally’ friendly fishing.
