Did you know that aquaculture is an important development in aquatic science and human civilization? James H. Tidwell et.al 2019 noted that Aquaculture (commonly spelled as aquiculture), also known as aqua-farming, is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other organisms under controlled or semi-controlled conditions. It is an ancient art that has been advanced by scientific principles during the last 100–150 years. The application of Aquaculture has been GROWING IN NEARLY ALL REGIONS OF THE GLOBE. 

In the Philippines, Aquaculture has a long history. Most of the production from aquaculture comes from the farming of seaweed, milkfish, tilapia, shrimp, carp, oyster, and mussels. Aquaculture contributes significantly to the country’s food security, employment, and foreign exchange earnings. Aquaculture is growing much faster than capture fisheries.

However, according to National Aquaculture Sector of FAO, the global position of the Philippines in aquaculture production has fallen steadily from 4th place in 1985 to 12th place today. The Philippines now contributes only a little over one percent of global farmed fish production compared to five percent previously. This is why making aquaculture more effective and productive is essential.


The future growth of Philippine aquaculture may not be sustained unless new markets are developed, market competitiveness is strengthened, and farming risks are reduced. In this age of international trade and competition, the Philippine aquaculture industry needs to plan and implement a development and management programme with a global perspective.

Presently, an organic product known as humic acid represents a new development that shows potential and is being widely used to address proper management of the animal farms and applicable to most of aquaculture. Humic acids or substances are well-recognized as safe to the environment and all living organisms. The data below are studies wherein humic substances provide remarkable results specific to the aquaculture industry.



One of the approaches to improve aquaculture production is through improvement of fertilization program for phytoplankton production and water quality variables. There are serious problems with the use of raw organic fertilizer in ponds and environment. Oxygen depletion, degradation of water quality, reduced light penetration, and spread of diseases frequently occur after large doses of manure are added to a pond at irregular intervals.

An experiment was conducted at the Gharehsoo Station of Fisheries Research Centre of Mazandaran (FRCM) in North of Islamic Republic Iran (July and August 1999) to study the effects of HA and inorganic fertilizer (urea and single super phosphate) on growth of selected freshwater phytoplankton and water quality variables. The experiment was carried out in eighteen 1.5 Liter transparent plastic bottles (control , 25 ppm HA+UP, 50 ppm HA+UP, 100 ppm HA, 100 ppm HA+UP, 150 ppm HA+UP). Three species of green algae (Chlorella vulgaria, Scenedesmus quadricauda, and Oocystis solitaria) and a species of blue-green alga (Oscillatoria agardii) were selected for the study. The results showed that highest population (bloom) was achieved in week 3 by 100 ppm HA. All treatments with a combination of HA and urea-phosphate led to a blue-green algal (Oscillatoria agardii) dominancy with a low phytoplankton bloom and low total nitrogen (TN) and total phosphorus (TP) ratio (0.7-1.03). The green algal dominance was associated with a high TN:TP ratio (16-17) in culture media. pH of HA treatment was within the suitable range (7.84-8.51) for phytoplankton production. Light penetration correlated well with blue-green algal population.



The object of the present invention is to provide a humic acid vannamei feed, it is effective to improve the water quality shrimp, prawns enhance immunity and disease resistance, to make up for deficiencies of the prior art.

The present invention includes the following parts by weight and the ratio of the group: humic acid 1-5 kg, 15-25 kg of red fish meal, soybean meal 10-20 kg, 10-15 kg of peanut cake, 3-7 kg of rapeseed meal, bone meal 3- 10 kg, squid viscera powder 3-8 kg, 16-25 kg of high-gluten flour, soy lecithin 1.0-2.0 kg, sea fish oil 2.0-3.0 kg, 0.3-0.6 kg of choline chloride, vitamin C- phosphate 0.05 0.1 kg, 0.5 to 1.0 kg of calcium dihydrogen phosphate, 0.2 to 0.5 kg of the multidimensional complex, composite mineral salts 0.3 to 0.7 kg.

The present invention significantly enhance immunity and disease resistance of the shrimp, improve the survival rate. Shrimp excreta reduction of nitrogen, phosphorus and heavy metals content such as iron, copper, zinc, manganese, cobalt, complexation of heavy metal ions adsorbed body shrimp, prawn facilitate environmental protection and food safety; origin of raw materials used in the present stable feed , low prices.

Detailed ways

Humic acid weighed three kilograms, 22.6 kilograms of red fish meal, soybean meal 16.6 kg, 13.6 kg of peanut cake, rapeseed meal 6.6 kg, 6.2 kg meat and bone meal, squid viscera powder 5 kg, 20 kg of high-gluten flour, soy lecithin 2 kg , 2.5 kg sea fish oil, choline chloride 0.5 kg, 0.1 kg vitamin C- phosphate, calcium dihydrogen phosphate 0.5 kg, 0.3 kg of composite multi-dimensional, complex mineral salt 0.5 kg. In addition to the high-sea fish oil, the raw material pulverized through 80 mesh sieve, then uniformly mixed, granulated by shrimp feed production line, namely feed Penaeus humic acid. Composite used in the present invention and the multi-dimensional composite mineral salts are known (see Schuhmacher et, Aquacuiture (1997), 151: 15-28). Vitamin C- Vitamin C content of phosphate is 35%.

Culture tests proved: compound feed according to the present invention can satisfy the general shrimp ponds, all the nutrients required under conditions of high breeding ponds, vannamei rapid growth, disease resistance, feed conversion ratio, feed efficiency 0.9-1.1. Compared with common commercial feed, the feed rate of digestion and absorption of the present invention, the breeding process feed nitrogen, phosphorus and excreta 32.8% 28.5% decrease, respectively; heavy metal elements iron, copper, zinc, manganese, cobalt utilization were increased ~ 1.55 2.89 times, shrimp survival rate of 85%.



This study investigated the effects of dietary humic acid sodium salt on growth performance, haemato‐immunological and physiological responses, and resistance of rainbow trout, Oncorhynchus mykiss to Yersinia ruckeri. The experimental fish were divided into four groups; three of them were fed with humic acid incorporated diets (0.3% H3, 0.6% H6, 1.2% H12) and an additive free basal diet served as the control. Growth performance and haematological parameters of rainbow trout were not affected by humic acid supplemented diets (p > 0.05). However, dietary humic acid especially with 0.6% incorporation significantly increased stomach pepsin, intestinal trypsin and lipase activities p < 0.05. Following 60 days of feeding trial, fish were challenged with Yersinia ruckeri for 20 days.

At the end of the challenge period, significantly higher (p < 0.05) survival rates were found in the 6% humic acid group compared to all other experimental treatment. Thus humic acid might replace antibiotics in diets for rainbow trout to control yersiniosis.



As you can see based on the scientific data, humic acid and its application can have significant impact on aquaculture and aqua-farming efficiency and productivity. This is why products that incorporate humic acid would have great potential in improving aquaculture businesses.

There are lots of products in the market for livestock farming. But, if you’re one that is careful enough to choose a product that would give you the best result for your aquaculture, please check out RED GRAND HUMIVET at website address: https://redinc.net/product/grand-humivet/, for details.
