This research aims to design 5R character-based halal industry players (Ringkas, Rapi, Resik, Rawat, Rajin) or 5S (Sort, Set in Order, Shine, Standardize, Sustain), as well as their debriefing for UNY and IIUM students in supporting the Halal industry related to Good Aquaculture Practices. This area has been selected, due to some factors. The first is the occurrence of several cases of aquaculture products that changed status from being permissible to become impermissible due to the external factors, for example, the fact that the water quality is bad and contaminated with harmful chemical substances. Water quality is the most important factor affecting fish health and performance in aquaculture production system. Secondly the fish nutrition and feeding are mixed with unclean and filthy ingredients. Thirdly, it is exposed to the risk of contamination from the equipment, which eventually affects halal integrity. Halal products cannot be prepared, processed, or manufactured using equipment that is contaminated with non-halal substances (unclean defined by Shariah). Contamination can be caused by equipment that is contaminated or used together with non-halal products. Therefore, equipment and machinery used in the halal aquaculture industry play a very important role to ensure halal integrity. This paper uses a library and literature review approach. It is expected that with the arrangement of 5R or 5S-based character strengthening design, the operators of Aquaculture Industry may preserve Halal Supply Chain.

Fish health is an important problem faced by Cantang grouper (Ephinephelus sp.) Hatcheries. Broodstock health management needs to be managed properly so as not to decrease the quality and production of Cantang grouper seeds. Cantang grouper broodstock health management includes the process of maintaining grouper broodstock, feeding, disease control and water quality management. The data collection method is done by recording the results of active participation, interviews and observations. Broodstock grouper cantang are maintained in ponds made of concrete with sizes ranging from 150 meter kibik and a depth of 3 meter. Pond cleaning is carried out once or twice a month with the addition of 2 kg of chlorine / 150 tons of water. Grouper broodstock is fed 10 kg for 24 broodstock. feed in the form of trash fish, squid, mackarel, vitamin C and vitamin E. The types of diseases that often attack grouper broodstock are Criptocaryon irritans, Benedia sp and Vibrio alginolyticus. Water quality parameters measured in grouper broodstock ponds are salinity and temperature. The water salinity in broodstock ponds ranges from 34 - 35 ppt and temperatures range from 27-31 derajat celcius.

And Performance

Total-reflection X-ray fluorescence spectrometry, abbreviated as TXRF, is known for its high sensitivity down to the low pg-level or sub-ppb level, respectively, and its wide dynamic range of about three to four orders of magnitude (Yoneda and Horiuchi, 1971, Wobrauschek and Aiginger, 1980; Knoth and Schwenke, 1978 and 1980, Aiginger and Wobrausohek, 1985, Michaelis et al., 1985, Prange, 1987). Meanwhile several laboratories have purchased commercially available TXRF spectrometers and have started to report favourable about this technique. Applications have been reported from various disciplines: These are estuarine and marine water quality management and research, air pollution studies, mineralogical investigations, biology and medicine (Prange, 1987, Prange et al, 1985; Prange and Kremling, 1985, Prange et al., 1987, Stöβel and Prange, 1985, Michaelis, 1986, Ketelsen and Knöchel, 1985, Leland et al., 1987, von Bohlen et al., 1987, Junge et al., 1983, Hentschke et al., 1985, Hentschke et al., 1985, Gerwinski and Goetz, 1987, von Bohlen et al., 1987), In spite of its close kinship to conventional EDXRF , TXRF is quite different with respect to operation and performance and provides complementary capabilities.

In order to determine the lethal dose (96-h LD50) of the bacteria Aeromonas hydrophila to matrinxã, Brycon amazonicus, to be applied in challenge tests, 90 fish (63.23 ± 6.39 g) were divided into five treatments, with different bacterial solutions: T1 - Control (0.9% NaCl saline solution); T2 (4 x 10(11) cells/ mL); T3 (5 x 10(11) cells/ mL); T4 (1.36 x 10(12) cells/ mL) and T5 (3.06 x 10(12) cells/ mL). Fish were previously anesthetized with benzocaine (60 mg L-1), inoculated in the peritoneal cavity with the bacterial suspensions and then distributed into fifteen 80-L test chambers, where the water variables were monitored and fish mortality was observed. The experiment was randomly designed in three replicates and the 96-h LD50 was estimated according to the trimmed Spearman-Karber method. Water quality variables remained within adequate ranges for fish health and performance. Fish mortality rate increased with the bacterial concentrations of A. hydrophila (T1 = 0%; T2 = 16.66%; T3 = 44.44%; T4 = 72.22% and T5 = 100%), and the first mortalities were observed after 57 h, although the signs of the bacterial infection were already observed 24 h after the inoculation. The results indicate that the 96-h LD50 value of A. hydrophila to matrinxã is 6.66 x 10(11) cells/ mL.

Water quality is the most critical factor affecting fish health and performance in aquaculture production systems. Fish life is mostly dependent on the water fishes live in for all their needs. Therefore, it is essential to have a clear understanding of the water quality requirements of the fish. This research discusses the critical water parameters (temperature, pH, nitrate, phosphate, calcium, magnesium, and dissolved oxygen (DO)) for fisheries and reviews the existing sensors to detect those parameters. Moreover, this paper proposes a prospective solution for smart fisheries that will help to monitor water quality factors, make decisions based on the collected data, and adapt more quickly to changing conditions.

A perfected method of setting norms of permissible impact in terms of chemical substances’ input into a water body has been presented. This enables to set representatively and differentially norms of adverse impact in terms of pollutants' input to a water-economic section both in respect of their total permissible input and in respect of the waste waters discharged from the pollutant sources at the said section. The method includes the mechanism of calculation of pollutants normal discharge (mass-transfer) to the downstream part of the water body; this enables to supplement substantially the list of indicators to be normalized, this facilitates effective water quality management at water/economic areas.

And Performance

Adaptive management has been promoted as a structured approach to learning in response to the uncertainty associated with managing complex systems. We developed and tested a protocol to guide an adaptive approach to water quality management in north-eastern Australia. The protocol articulates a framework for documenting uncertainties and performance expectations, negotiating feedback and anticipating iterative and transformative responses to future scenarios. A Water Quality Improvement Plan developed for the Tully–Murray catchment in the Great Barrier Reef region was used to test the protocol and three benefits of its use were identified. First, developing rigorous and timely monitoring and evaluation ensures that opportunities for iterative planning are realised. Second, anticipating future endogenous or exogenous changes to the plan enables the early initiation of actions to inform transformative planning responses. Finally, the protocol exposed the need to coordinate multi-scalar responses to tackle environmental knowledge and management uncertainties and assumptions. The protocol seeks to provide a practical translation of adaptive planning theory that will enable the benefits of adaptive management to be realised on the ground.
