Abstract

The aim of this study is to determine the best salinity level on latent and eggs production of Banggai Cardinal (Pterapogon kauderni Koumans 1993) based on first brood and brood production of Banggai Cardinal in the treatment. Water quality measurement was carried out every day to maintain water quality. Water quality measurement showed suitable salinity for Banggai Cardinal breeding. Brood latent showed no significant difference between the treatments. Total of 27 ppt is the level of salinity for Banggai Cardinal reproduction to gain positive respond on eggs production (42.3333 ± 7 eggs). Keywords: Banggai Cardinal, Eggs Production, Latent, Salinity.

Abstract

Accumulated the toxic compound such as lead in A. woodiana caused an alteration in tissue. The aim of the present study is observation through histology to determine the alteration of the structure of digestive diverticulum tissue. A. woodiana were maintained in water tub that treated lead II nitrate exposure (Pb(NO3)2) 0, 15, 25, 35 mgL-1 for 7 days to determine the alteration of the structure of damaged the digestive diverticulum and determining water quality such temperature, DO and pH. The highest damage occurs in digestive diverticulum treated 35 mgL-1  due to the many alteration tissue structure such as hyperplasia, edema, atrophy, necrosis with the percentage of total damage of about 35%. the lowest alteration tissue structure occurs in 15 mgL-1 treatment group of the digestive diverticulum. the temperature was observed at about 25.3 - 26.4°C, pH about 6-7, and DO about 6.1-6.7 mgL-1. Thus, the increment of lead dose treatment induces increment of tissue structure alteration in digestive diverticula tissue, therefore, might promote the death of Anodonta woodiana. Keywords: Anodonta woodiana, digestive diverticulum, histology

Abstract

The problems of fish and plant cultivation are limited land, decreasing quality and quantity of water for human needs, food sources, and increasing population on earth. Optimization of fish farming with high stocking densities accompanied by high feeding will cause accumulation of organic matter in the culture containers which will worsen the quality of the rearing water which will ultimately have an impact on the physiological conditions, survival and growth of fish. One of the technologies for growing vegetables, fruit and fish farming that has been developed to overcome these obstacles is the Budikdamber system with red tilapia organisms and water spinach plants. The purpose of this study was to determine the quality of water with different stocking densities in the Budikdamber system with water spinach and without water spinach. The experimental design used a factorial complete randomized design with density treatment (A (2 fish/10L), B (4 fish/10L), C (6 fish/10L), D(8 fish/10L) and system (budikdamber with water spinach) (a) and without water spinach (b)). The results showed that temperature parameters ranged from 22.4 - 30.6°C, pH ranged from 6.4 - 8.9, and DO ranged from 1.07 - 16.4 mg/l. Parameters of temperature, pH, and DO are in a range that is not in accordance with optimum conditions (temperature = 25-32°C, pH = 6.5 – 8, and DO ≥3 ), but can still be tolerated by tilapia so that fish tilapia still survive. Water spinach plants can reduce ammonia so that the ammonia value in the treatment using kale decreased from week 1 to 4 and conversely, for budikdamber without water spinach, it increased from week 1 to week 4. The highest SR value was found in the Ba treatment (4 fish/10 liters) with water spinach is 91.67%.
