Abstract

Catfish is one of the commodities with promising prospects for development, both in hatchery and grow-out activities. One of the challenges in catfish farming is the high mortality rate of intensively raised fish without water exchange. In order to increase production, the implementation of good cultivation technologies is necessary to maximize the results. One such technology that can be used is the Recirculating Aquaculture System (RAS). This study aims to analyze the effects of RAS using lettuce plants as biofilters on the growth and survival of Clarias gariepinus catfish. The test animals used in this study were Clarias gariepinus catfish sourced from Beta Fish Lingsar Farm, with seed size ranging from 7-8 cm. The study was conducted with three treatments (plots): pond 1 = RAS with lettuce biofilter at a stocking density of 1000 individuals, pond 2 = RAS with a stocking density of 1000 individuals, and pond 3 = RAS with a stocking density of 500 individuals. The results of the study showed that the use of the RAS system had an impact on the growth and survival of the fish. The RAS system with lettuce biofilter was able to increase the Specific Growth Rate (SGR) by 6.02% and reduce fish mortality rate with a Survival Rate (SR) value of 62.8%. Based on these findings, the use of RAS with plant biofilters can be further developed on a larger scale in aquaculture.

Abstract

Seaweed commodities are one of the products in the fisheries and marine sector that has the potential to be developed. One type is sea grape or commonly known as Caulerna lentillifera which is very widely spread in waters throughout Indonesia. This research method is descriptive quantitative, this research was conducted to determine the heavy metal content in natural sea grapes and cultivated sea grapes. The research procedure consisted of pre-research process to observation and checking of heavy metal content. The results of research on heavy metal content of cultivated sea grapes get good results, while for nature there are levels of heavy metals Pb so it can be said that it is not very good. The results of measuring the length of ramuli in the first week was 3.3 cm, the second week was 4.4 cm then increased in length in the third week to 5.8 cm, and ended in the fourth week with an increase in length of 6.9 cm. The results of the calculation of the number of ramuli in week 1 showed that the average number of ramuli was 12, the average number of ramuli in the first week increased to 14 in the second week and increased in the third week to 17 then ended in the fourth week with an average of 19 ramuli. The quality of water used in the cultivation of sea grapes in Musi Village and natural sea grapes is still in normal status.

Abstract

The seagrass ecosystem is an ecosystem that is very important to support the sustainability of the biota that take shelter in it. The seagrass ecosystem is known as one of the areas that is vulnerable to damage. Various human activities, such as fishing and industrial activities can trigger this damage. This study aims to provide information regarding the description and level of degradation of the seagrass meadow ecosystem in Uwedikan Village. The method used is random sampling method. The results showed that there were 5 species of seagrass found, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea Serullata, Cymodocea rotundata and Halophila ovalis. Seagrass cover averaged 40.60% at Tanjung Balean and 33.1% at the Tambatan Perahu. This is included in the moderate/less rich category. The highest seagrass cover was for Thalassia hemprichii with a total of 2,169 individuals at Tanjung Balean and 1,453 at the Boat Mooring. The relationship of water parameters, namely temperature, degree of acidity (pH) and brightness greatly affect the growth of seagrass ecosystems. In particular, the temperature at the two locations obtained different values, namely 29--30.5°C at Tanjung Balean and 30--35.3°C at the Tambatan Perahu.

Abstract

Silkworms, as natural food, have an essential role because they can stimulate fish growth. However, silkworms in nature are not always available all year round, so it is necessary to cultivate silkworms. Silkworms need a medium containing organic matter and inorganic matter for their growth. Catfish farming wastewater contains a lot of organic matter. This study aims to evaluate the effect of catfish farming waste (Clarias sp.) on the growth of silkworms (Tubifex sp.) in different initial biomasses. This research method uses the experimental method Complete Randomized Design with four treatments and three repeats. The treatment used is P1 = 15 grams of silkworms; P2 = 20 grams of silkworms; P3 = 25 grams of silkworms; and P4 = 30 grams of silkworms. For analyzing data use ANOVA with a 95% confidence level and the Lower Significance Difference test on SPSS. The results showed that the provision of catfish farming waste had a real influence on the growth of silkworms. Silkworms' absolute weight and biomass were highest in treatment four, which were 195.33 g and 0.112 g. Therefore, catfish farming waste has the potential to be used as raw material for silkworm feed.

Abstract

Catfish is a freshwater consumption fish that is most widely cultivated in Indonesia, occupying the top position in total production, catfish has contributed more than 10% of the national aquaculture production with a growth rate of 17 to 18%. Catfish has a fairly high protein content and is very competent to improve human nutrition, because it is classified as a high quality food and its uniqueness is a must. Due to the high density of cultivation, a technology is needed that supports the maintenance of oxygen content, namely microbubble. This research was conducted for 50 days by observing the growth of catfish in 3 different conditions, namely without aerator, with conventional aerator and microbubble. The results showed that the absolute weight and absolute length without aeration were 5.2 g and 3.5 cm. then with a conventional aerator it produces 5.3 g and 3.5 cm. and on Microbubble it is 9.2 g and 7.2 cm. Judging from some of the parameter test results, it shows that raising catfish using microbubble increases the growth rate and productivity of catfish.

Abstract

The need for tilapia fish supplies for the world market is not yet fully met, so the implementation of intensive cultivation is expected to increase aquaculture production results. Recirculation systems are an option for controlling the quality of cultivation water, and the addition of UV lights is expected to be able to kill bacteria found in cultivation waters. This research aims to evaluate the use of UV lamps in fish nurseries and analyze the best use of UV lamps in tilapia nurseries. This research was carried out for 45 days, at the Fish Production and Reproduction Laboratory, Mataram University using an experimental method with a completely randomized design (RAL) consisting of 4 treatments and 3 replications, namely P1: without UV lamp, P2: 5 Watt, P3: 10 Watts, and P4: 15 Watts. Test parameters include absolute length growth rate, specific length, absolute weight, specific weight, Feed Conversion Ratio (FCR), Survival Rate (SR), water quality and bacterial abundance. Data were analyzed using Analysis of Variance (ANOVA) and continued with the Duncan test. The results showed that the best growth rate parameters, Feed Conversion Ratio (FCR), Survival Rate (SR) and bacterial abundance were found in P4 with an absolute length growth rate of 6.4cm, specific length of 0.05%/day, absolute weight growth of 9.7gr, specific weight of 0.06%/day, Feed Conversion Ratio (FCR) value of 0.7, Survival Rate (SR) of 94% and bacterial abundance of 5.7 x 105 CFU/ml.

Observations for productivity calculations were carried out 10 times. Organoleptic test results for raw materials scored 8 while organoleptic frozen tuna loin products scored 8. Microbiological test results for tuna loin products ALT 1.7 X 10³ col/g, E. coli <3 APM/g, Salmonella negative. The result of trimming yield test (trimming l) was 96.53%, and trimming II was 90.26%, while the result of trimming productivity test (trimming l) was 104.42 kg/hour/person and trimming II) 152.21 kg/hour/person. Overall frozen tuna loin products comply with SNI standards for frozen tuna loin (7968: 2014).
