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.

Abstract

Catfish (Clarias sp.) is one of the many fishery biota that has animal protein which is much loved by Indonesian people. One way to develop environmentally friendly catfish cultivation is through the implementation of an aquaponic biofilter system. This research aims to analyze physical, chemical, and biological water quality parameters in catfish cultivation with and without aquaponics, to obtain a description of the non-specific immune system which is analyzed from the conditions of phagocytic activity of catfish cultivated with and without aquaponics. The method used is by taking samples ten times per week by taking water quality parameters as well as blood samples of catfish raised in ponds with and without aquaponics. The analysis used is the unpaired T-test. Based on the results obtained, it was concluded that all parameters showed that the aquaponic cultivation media was better compared to those without aquaponics.

Abstract

Intensive ponds often experience a decrease in water quality and cause ponds to bloom due to the fertility of the pond bottom due to the buildup of organic material originating from leftover feed, feces and the remains of dead shrimp. The aim of this research is to determine the relationship between water quality and phytoplankton abundance in intensive pond types with different densities in Bayeman Village, Probolinggo Regency. The research was carried out from January to March 2023. Samples were taken using the purposive sampling method in 6 different pond plots. Phytoplankton analysis was carried out at the Laboratory of the Sand Source Freshwater Fisheries Technical Implementation Unit and the Hydrobiology Laboratory of the Fish Resources Section of the Faculty of Fisheries and Marine Sciences. Measurement of in situ water quality parameters, namely temperature, pH, brightness, DO, TDS, light intensity, salinity and ex situ nitrate, phosphate and ammonia using spectrophotometric methods. The correlation test results of physico-chemical parameters related to phytoplankton abundance have a strong and heterogeneous relationship only with the orthophosphate parameter
