Efficacy of Apocyclops royi (Cyclopoida, Copepoda) Nauplii as Live Prey for the First Feeding Larvae of Silver Pompano, Trachinotus blochii (Lacepède, 1801)
No full textIn the rearing of first exogenous feeding, marine finfish larvae availability of live prey with suitable size and nutritive content is vital for their growth and survival. Copepods represent an important alternative food to present traditional live feed organisms used in marine fish hatcheries. Use of copepods is known to improve survival, growth, and development of fish larvae. The silver pompano, Trachinotus blochii (Lacepède, 1801) is one of the suitable candidate species for aquaculture due to its fast growth, good meat quality and high market demand. The present study aimed to investigate the efficacy of Apocyclops royi nauplii in the rearing of first feeding larvae of T. blochii. The feeding experiments were conducted from 3 to 7 Day Post Hatch (DPH) using A. royi nauplii and Brachionus plicatilis (s type) diets. Higher growth of T. blochii larvae was evident with A. royi nauplii than that of rotifer diet. The A. royi nauplii fed experimental group of T. blochii larvae showed significantly different length (p <0.05) compared to rotifer fed larvae and the specific growth rate recorded was 29.42% and 24.28% in A. royi and rotifers fed experimental groups, respectively. On 7 DPH, A. royi nauplii fed T. blochii larvae showed higher mortality than rotifer fed group. With A. royi feed T. blochii larvae produced higher pigmentation which gradually started on the head and dorsal surface of the body from 3 DPH onwards and spread all over the body and became intense as the larvae grew to 7 DPH. Our results suggest the A. royi nauplii are suitable live prey for the T. blochii larvae during the initial feeding phase for better growth and pigmentation
Role of the Plant Morinda citrifolia L. in Management of Diseases in Fish Cultured: A Mini-review
No full textProduction failure in fish farming activities, one of which is caused by disease. So the prevention of disease needs to be done by using environment friendly technology. Disease control efforts can be carried out through preventive and curative measures. Preventive measures can be taken by increasing the immunity of fish. The use of herbal ingredients is relatively safe for fish and the environment to be used as a source of drugs or immunostimulants. Morinda citrifolia is one of the medicinal plants that contains various types of active ingredients that are antibacterial and immunostimulant, including alkaloids, flavonoids, tannins, saponins, steroids, phenols and terpenoids, glycosides, carbohydrates, coumarine and scopoletin. Therefore, M. citrifolia, both the fruit and the leaves, can be used for treatment and prevention of diseases that attack cultured fish. The purpose of writing this article is to describe several research results that prove the ability of parts of the noni plant, namely the leaves and fruit to be used as drugs or immunostimulants as an effort to control diseases in cultured fish. Several studies have shown that noni plays a role in overcoming diseases that infect cultured fish, both for treatment and prevention. The parts of M. citrifolia plant used are the leaves and fruit in various dosage forms, namely extract, flour and juice. The types of diseases that can be cured are bacterial diseases caused by Aeromonas hydrophila that infect Leptobarbus hoevenii, Cyprinus carpio, Barbonymus gonionotus, Carassius auratus and Oreochromis niloticus fish and parasitic diseases caused by Argulus sp., Lernaea sp. and Trichodina sp. Several types of fish, namely Cyprinus carpio, Oreochromis niloticus and Penaeus monodon increased body resistance after being treated with M. citrifolia, which was indicated by an increase in the number of leukocytes, an increase in total phagocytic activity and high survival after being challenged with pathogenic organisms

No full textSpatio–temporal variation in Chlorophyll, Nutrients and Primary Productivity of some selected sampling stations in Lagos lagoon were investigated using conventional method from November 2019 to July 2020, in order to compare the result with data from satellite image using MODIS Aqua. Global Positioning Receiver was used to capture the geographic coordinates of the sampling stations. Water sampling was carried out monthly using standard methods during wet and dry seasons. The observed data were subjected to statistical analysis using Microsoft Excel and SPSS version 20. In wet season, the highest mean value for Chlorophyll a (1.15±0.02 µg/L) was recorded in Ofin while the lowest values (0.06±0.01 µg/L) was observed in Okobaba. During the dry season, the highest mean value (0.75±0.10 µg/L) was in Ofin while the lowest mean value (0.27±0.0.08 µg/L) was recorded in Ibeshe. The MODIS satellite variation in chlorophyll-a showed that the highest value of highest recorded value (1.37±0.00 µg/L) was in wet season (Ijede) while the lowest value (0.12±0.01 µg/L) was observed in dry season (Okobaba). The highest transparency value (0.97±0.01 mg/L) was recorded in dry season (Ofin) while the lowest value (0.35±0.25 mg/L) was recorded in wet season (Oworonsoki). The highest mean value of Surface Sea temperature was recorded in the dry season of Apapa (30.28±1.15oC) while the lowest mean value (26.41±1.15oC) was observed in Okobaba in the wet season. The chlorophyll-a concentration analyzed using standard method and MODIS satellite, in both dry and wet seasons in the sampled stations differ greatly from one another in terms of the mean concentration. The primary productivity of Lagos Lagoon was relatively low, with no significant spatial variations between sampling stations. The results of sea surface temperature, transparency and chlorophyll ‘a’ estimation from the MODIS revealed that the values were positively correlated with laboratory result with r2-value of 0.67, 0.80 and 0.77. This indicates that MODIS data and laboratory results generated for Lagos Lagoon were positively related
