The focus of this study was to develop true reflectance surfaces in the visible portion of the electromagnetic spectrum from small unmanned aerial system (sUAS) images obtained over large bodies of water when no ground control points were available. The goal of the research was to produce true reflectance surfaces from which reflectance values could be extracted and used to estimate optical water quality parameters utilizing limited in-situ water quality analyses. Multispectral imagery was collected using a sUAS equipped with a multispectral sensor, capable of obtaining information in the blue (0.475 μm), green (0.560 μm), red (0.668 μm), red edge (0.717 μm), and near infrared (0.840 μm) portions of the electromagnetic spectrum. To develop a reliable and repeatable protocol, a five-step methodology was implemented: (i) image and water quality data collection, (ii) image processing, (iii) reflectance extraction, (iv) statistical interpolation, and (v) data validation. Results indicate that the created protocol generates geolocated and radiometrically corrected true reflectance surfaces from sUAS missions flown over large bodies of water. Subsequently, relationships between true reflectance values and in-situ water quality parameters were developed.

Catfish (Pangasius sp.) is a dominant consumption fish and it is targeted that production will be increase every year. Catfish have a low feed efficiency value which is causes the growth of catfish to be less optimal, so it is necessary to add ingredient into the diets so that the fish are interested in eating the diets given. The use of earthworm meal as an attractant was expected to increase of feed consumption, feed efficiency and growth of catfish. This experiment aimed to study the effect of dietary earthworm meal as an attractant on feed consumption level, feed efficiency and growth of catfish (Pangasius sp.). The catfish used with an initial average body weight of 6,78±0,68 g/fish. The fishes were cultured in the aquarium for 42 days with the stocking dencity of 1 fish/2L. The experimental method used was completely randomize design (RCD) with 4 treatments and 3 replicates.  The treatments were addition of earthworm meal (Lumbricus sp.) as an attractant with a dose of 0%, 5%, 10% and 15% in the diets. The data showed that  the use of earthworm meal (Lumbricus sp.) inclusion in the diets resulted in significant effects (P <0,05) on feed consumption  (159,73 g), FE (81.06%), PER (2,31%), G (9,76 g) and SGR (1,97%/day) but not significant effect (P>0,05) on survival rate (84.44-93,33%). The best food preference test in treatment C dose 10% of earthworm meal with percentage 44% fish approaching diets. The water quality parameters during this study varied between suitable range for the catfish (Pangasius sp.) life, i.e temperatures 27,70-30,900C; pH 7,00; DO 5,37-5,52 mg/L and NH3 0,0036-0,0095 mg/L. It was concluded  that catfish (Pangasius sp.) fed with the diet containing 10% attractants of earthworm meal resulted in better feed consumption, feed efficiency and growth.

Water quality index (WQI) provides a single number that expresses the overall water quality, at a certain location and time, based on several water quality parameters. The objective of WQI is to turn complex water quality data into information that is understandable and usable by the public. A number of indices have been developed to summarize water quality data in an easily expressible and easily understood format. The WQI is basically a mathematical means of calculating a single value from multiple test results. This chapter discusses, in detail, the application of a water quality index for the assessment of water quality to different several water sources in Nigeria.
