Abstract

An important aspect in tilapia cultivation is observing the relationship between the length and weight of the fish, which is an indicator of the fish's growth. One of the areas in West Nusa Tenggara that has great potential in tilapia cultivation is Gerung which is located in West Lombok Regency. The purpose of this study is to determine the growth pattern of tilapia in the region to help farmers adjust feed management, stocking density and maintenance systems to increase production. The method used is the survey method and regression analysis. The number of samples used in this study were 16 tilapia (Oreochromis niloticus) taken randomly from tilapia rearing ponds in Gerung District, West Lombok Regency. The average weight obtained in this study ranged from 169-400 grams with an average of 285 grams and a length of 25-39 cm, while the results of statistical regression of the relationship between the length and weight of tilapia, the regression equation obtained a value of Log Y = 25.419X 0.7394 with a correlation value (R2) of 43% and a value of b = 0.73, so that b <3 which means negative allometric where the condition of the fish experiences faster growth in length than weight gain

Abstract

ABSTRAK Transportation of live fish such as cantang grouper Epinephelus fuscoguttatus × Epinephelus lanceolatus is at risk of causing stress that can reduce survival rates. This study aims to determine the optimal dose of red guava leaf extract Psidium guajava Linn as a natural anesthetic to improve fish survival during transportation. This research will be conducted in December 2023 and conducted in two places, namely at Hatchery D' Marine Aquaculture and Kampung Madong. The research used a Completely Randomized Design (CRD) with four treatments, namely: K control (0 ml/L), A addition of red guava leaf extract (4 ml/L), B addition of red guava leaf extract (6 ml/L), and C addition of red guava leaf extract (8 ml/L), each with three replications. The parameters observed included survival rates after transportation and during maintenance, blood glucose levels, fish behavior, and water quality. The results showed that all treatments had a 100% survival rate after transportation. During 7 days of maintenance in floating net cages, treatment A showed the highest survival rate (100%), followed by K (86.67%), C (80%), and B (48.33%). The lowest blood glucose levels occurred in treatment B (56.67 mg/dL), while the highest was in the control (92.33 mg/dL). Fish in treatment A also showed the best behavior and feed response. These results indicate that the addition of red guava leaf extract at a dose of 4 ml/L is effective in reducing stress and increasing the survival of cantang grouper during and after transportation.

Abstract

Nitrogen is one of the nutrients needed by Nannochloropsis sp., but there has been no determination of fertilizer dosage based on fertilizer nitrogen sources. This study aims to determine the provision of inorganic fertilizers capable of substituting urea in the culture nutrients of Nannochloropsis sp. and to find out inorganic fertilizers that are effective for use as a nitrogen source for the Nannochloropsis sp. cell population. This study used a Completely Randomized Design (CRD) with 1 control and 3 treatments, namely: Control (Urea 50 mg / L Urea, Za, TSP, EDTA), treatment A (NPK Fertilizer 16 16 16, Za, TSP, EDTA), treatment B (Calcium Nitrate Fertilizer, ZA, TSP, EDTA), treatment C (Calcium Ammonium Nitrate Fertilizer, ZA, TSP, EDTA), each with 3 replications. The parameters observed included daily density, peak population, doubling time, water quality and light intensity. The results showed that during 7 days of maintenance, the highest daily density of Nannochloropsis sp. cells was found on D-5 of maintenance with the highest growth in treatment C (Calcium Ammonium Nitrate Fertilizer) which was 18,528,611 cells/ml with the fastest doubling time in treatment C (Calcium Ammonium Nitrate Fertilizer) which was 37.04 cells/hour and the lowest growth in treatment A (NPK 16 16 16 Fertilizer) which was 17,128,611 cells/ml with the longest doubling time in the control (Urea Fertilizer) which was 46.6 cells/hour. The peak population for the control and all treatments was found on D-5 of maintenance. The light intensity during the study ranged from 6,357 lux. These results indicate that NPK 16 16 16, Calcium Nitrate and Calcium Ammonium Nitrate fertilizers are able to substitute urea as a nitrogen source in the nutrient culture of Nannochloropsis sp. and the three organic fertilizers are effective in being used as a nitrogen source for the Nannochloropsis sp. cell population.
