Are There Any Possible Substitutes for Black Strap Molasses As a Bacterial Food? I Was Wondering Specifically About Sorghum Molasses Lesson 6 Live Q&A Webinar From Leticia Oberley: Are there any possible substitutes for black strap molasses as a bacterial food? I was wondering specifically about sorghum molasses. Well, what we’re finding out is when you look at your soil, you’ll see that you already have lots of bacteria and hopefully lots of different species of bacteria as well and so adding the black strap molasses or any kind of bacterial food is a little bit unnecessary. So, if you put too much of a bacterial food into the tea then it’s really hard to keep whole tea aerobic through the whole entire brewing process. So we are really trying to encourage people to not be putting in any kind of bacterial food into the system. Doesn’t seem to be really necessary but let’s say you do have that unusual situation where there aren’t enough bacteria in your soil, you want to increase diversity a little bit. Then sorghum molasses would work as well. You just want to try to pick something that has a wide diversity of different kinds of sugars. And that’s why the non-sulfured black strap molasses is so good because it’s got a 150 different kinds of sugars in it. I’d want to know the same kind of information about your sorghum molasses. How many different kinds of sugars? And that should be easily found out. If you go to the website of the company making the sorghum molasses, how many different kinds of sugars, and it would be pretty good. Beware of the fact that they typically put a preservative into molasses. They put sulfur compound which is a fungicide. Almost all of our fungicides are sulfur based and so having that sulfured molasses means it’s got that preservative in it and that of course is going to kill your organism. So, try to get the food quality, human food quality molasses if you feel like you need to use a sugar. Another alternative is a fish emulsion. In a fish emulsion they have taken a fish hydrolysates and cooked it and the heat causes the oils to separate on the top, all the proteins in the meat and everything else that sit on the bottom in a container start to break down because of the heat, they get to be simpler and simpler compounds, so really good for growing bacteria. Not so good if you’re trying to grow fungi. And oils are usually removed and so fish emulsion tends to have very little oil in it and then for very few fungal foods. So that would be another possibility. Any kind of sugary material - fruit juices work well, just remember the pulp is good for growing fungi. The actual juice part, where all the sugars are - that’s good for growing bacteria. So which kind of juice? Well you’d have to test them and find out which one grows the kind of bacteria that you want. From Damian: How do different ratios of black strap molasses, fish hydrolysate and seaweed affect compost tea? Yeah, when you put more bacterial food in, so, more black strap molasses, you’re going to put food in, you are putting food in for more bacteria and so you’re going to grow more bacteria. If you put more fish hydrolysate in then you’re going to grow more fungi. Seaweed - depends exactly what quality seaweed you have but it tends to grow more fungi than bacteria. So the more seaweed, the more fungi you’re going to end up with, more nutrients go into that tea. So what are you trying to do with your tea or even your extract? If you’re putting these things in at the last minute to put out foods to feed your compost extract organisms once they arrive in the soil, so, you can do that too to give some resuscitation, some foods for these organisms when they go into soil. So how do different ratios? Think about your bacterial food, your fungal foods, you mineral nutrients, fungal foods. How do they affect your compost tea, it’s going to make it more or less fungal or bacterial. 1 | Lesson 6 Live Q&A Webinar From Petra: When buying fulvic or humic liquid, could I just run a quick pH test to see if the material is too alkaline or too acidic to be useful instead of having to brew a tea for 24 hrs before I know if it is good? A pH test might not tell me if it grows fungi well but at least it would tell me if I will kill my soil life. Yeah, you could stick a little bit of litmus or if you got electrodes to show you pH or you buy one of those little handheld meters where you put a drop on and it tells you the pH. Anyone of those would tell you if you had neutralized the preservative that they put into the fulvic or the humic acid and so you would know whether that was actually truly taken care of before you put the compost in. And so typically in a tea we’re putting these food resources into the water first so you’d have a chance for the water to neutralize the phosphoric acid or the potassium hydroxide or whatever preservative they have put into that material. Make sure it gets diluted out so it shouldn’t kill your microorganisms. So you put your compost in last after you’ve got everything else going in there. And so a pH paper or quick pH test of some kind would let you know if the preservative has been neutralized. It’s not going to tell you about the quality of the food or the quality of microbial life you’re going to see. You want to let it brew and then at the end of the brewing time or maybe halfway through the brewing time or a couple of hours into the brewing time, you could pull a drop out of your tea and take a look at whether you’re seeing that increase in the numbers of fungi or the lengths of fungi or the numbers of the bacteria. And that would tell you way earlier than 24 hours whether things are going right or not in the brew. From Damian: How does seaweed affect a compost tea - what are the benefits and what are the problems? It’s a – usually, it’s a fungal food. It’s typically going to enhance fungal growth, it puts some nutrients into the compost tea so you may be balancing, upping the nutrient content of the compost tea. Of course you’re going to be extracting soluble nutrients out of the compost so you’re putting those into your compost tea. But let’s say you want little bit more nutrients going out there for your plants, especially if we are doing hydroponics or you’re doing aquaponics. Sometimes we need a little bit extra of that seaweed, the kelp, to give enough nutrients so our hydroponic plants are getting the nutrition that they need and of course that’s got to pass the normal nutrient cycling system providing nutrients in a plant available form. The problems are if you put in too much or if the seaweed actually has a salt problem. A lot of these seaweeds can have very high electrical conductivity, and so you need to be aware of that and maybe read the label and see what the electrical conductivity and please be aware that it needs to be in micro so the little µS sign, microsiemens per centimeter squared. And if what it’s reading, giving you on the label is deciesimons or centisiemons or dS or a cS per centimeter squared, don’t touch it, it’s way too salty. So you want something that has electrical conductivity in the microsiemens range. So those are the problems that come to mind right away. From Collin Attard: Question about seaweed (Kelp) as a fungal food in the compost and compost tea. 1. Is any old weed coming out of the sea going to be suitable replacement to kelp? Our beaches have truck loads of seaweed washed up on them every year. It is not the same as kelp. It is paper thin and usually 1 to 2 inches long, about 1/2 inch wide and dark brown in colour until it dries. You have to look at the nutritional content of that material and the reason kelp has gained the reputation is that cold water kelp contains more nutrients in it than any other kind of seaweed or any other kind of kelp. Southern or hot water or warm water kelp doesn’t contain as much nutrients. So in terms of adding nutrients into the compost tea, sometimes if you’re going into a soil that’s got related nutrient value, you don’t need to worry about it. And especially as I’ve come to understand that all soils have all of the nutrients in it that your plant requires the reasons our plants don’t grow in a lot of our agricultural fields because we’ve destroyed the life. And so there’s no way to get the nutrients out of your mineral material and into a plant available form until you get the biology back into the system. So, right at first, the kelp, the seaweed might be kind of 2 | Lesson 6 Live Q&A Webinar hedging your bet a little bit.

Accordingly, a remarkable increase in the amount of fish waste has been produced around the world; it has been estimated that about two-thirds of the total amount of fish is discarded as waste, creating huge economic and environmental concerns. For this reason, the disposal and recycling of these wastes has become a key issue to be resolved. With the growing attention of the circular economy, the exploitation of underused or discarded marine material can represent a sustainable strategy for the realization of a circular bioeconomy, with the production of materials with high added value. In this study, we underline the enormous role that fish waste can have in the socio-economic sector. This review presents the different compounds with high commercial value obtained by fish byproducts, including collagen, enzymes, and bioactive peptides, and lists their possible applications in different fields.

Inclusion of size fractionated fish hydrolysate in high plant protein diets for Atlantic cod, Gadus morhua. Aquaculture 261(3):1102-1110. Abstract: Fish hydrolysate was evaluated as feed ingredient in high plant protein diets in an 89 days feed experiment with Atlantic cod (Gadus morhua). The fish hydrolysate was size fractionated by ultra- and nano-filtration and the various fractions were tested specifically as feed ingredients to trace any effect observed with the hydrolysate. All diets contained 68% of total protein as plant protein, added as a mixture of corn gluten, full-fat soy bean meal, soy protein concentrate and extracted soy bean meal. The diets were equal in protein, lipid and energy. The control diet contained 21.8% fish meal. Fish hydrolysate was tested in another diet where one third of the fish meal protein was exchanged with the fish hydrolysate. Retentate after ultra-filtration of fish hydrolysate and retentate and permeate after nano-filtration were used in three separate diets at dietary inclusion levels corresponding to the absolute dry matter level of the fractions in the hydrolysate. The cod tripled in weight during the experimental period. No significant differences were observed for growth or feed intake for any groups. The diets containing retentate from ultra- and nano- filtration showed lower feed efficiency than the control diet with fish meal or the diet containing fish hydrolysate or permeate after nano-filtration. In conclusion the results show that fish hydrolysate may successfully be used as a protein source in high plant protein diets for Atlantic cod in exchange of fish meal.

    Fish protein hydrolysate in diets for Nile tilapia post-larvae Thiberio Carvalho da Silva(1), Joana D’Arc Mauricio Rocha(1), Pedro Moreira(1), Altevir Signor(1) and Wilson Rogerio Boscolo(1) (1)Universidade Estadual do Oeste do Paraná, Campus Toledo, Rua da Faculdade, no 2.550, CEP 85903-000 Toledo, PR, Brazil. E-mail: [email protected], [email protected], [email protected], [email protected], [email protected] Abstract – The objective of this work was to determine the apparent digestibility coefficient (ADC) of crude protein, crude energy, fat, and dry matter of fish protein hydrolysate (FPH), made of by-products of Nile tilapia (Oreochromis niloticus) and whole sardines (Cetengraulis edentulus), and to evaluate the productive performance and muscle fiber growth of Nile tilapia post-larvae. Two trials were conducted, the first one to determine the digestibility in 120 fingerlings (70.0±2.0 g), and the second one to evaluate the productive performance of 375 post-larvae, with three days of age, which were distributed in 25 aquaria with 30 L of useful volume. Five diets were prepared based on vegetable ingredients, to which fish were included at 0, 2, 4, 6, and 8% FPH. For the evaluation of muscle growth, eight fish of each experimental unit were used. The ADC values found were: 98.29% for dry matter; 99.28% for crude protein; and 99.13% for gross energy. The best zootechnical response for the productive performance resulted from the treatment with the inclusion of fish hydrolysate at 4.75%. The diets affected the frequency of the muscle fiber diameters, mainly the growth by hyperplasia.

    Advances in Seafood Byproducts 43 Alaska Sea Grant College Program • AK-SG-03-01, 2003 Utilization of Fish Byproducts in Iceland Sigurjon Arason Icelandic Fisheries Laboratories, and University of Iceland, Department of Food Science, Reykjavik, Iceland Abstract Fisheries are the single most important industry in Iceland, and will con- tinue to play an important role in the economy of Iceland for a long time to come. In 2001 the total catch was around 2 million tons, accounting for 62% of the country’s merchandise exports. The living marine resources are, however, limited and it is important to utilize these resources in a sustainable way. It is also important to maximize their value by produc- ing high-priced products from the raw material, which is currently be- ing used for fish meal or simply discarded. For example, today all cod heads from land-based processing plants are being utilized and lately the freezing trawlers have begun freezing them onboard for processing on shore. Fortunately, most of the byproducts are no longer regarded as waste but are used as raw material for fish processing like roe, liver, mince, viscera, etc. The byproducts from salting, freezing, and canning fresh fish and other processes have different qualities and potentials. Therefore, quality management is important and new technologies are emerging that will allow a new range of products to be made from byproducts which will, for example, benefit the pharmaceutical, cosmetics, and food industries worldwide. Introduction The living marine resources in Icelandic waters are the most important natural resources in the country. In 2001, the total catch was around 2 million tons, (Fig.

    Increase Sustainability of Fish Farms with the Development of Value Added Products from Fish and Fish Waste Final Report Project Number: FNC14-955 Type: Farmer/Rancher Project Region: North Central SARE GRANT: $13,746.00 Coordinators: Roy Landskron Project Coordinator, Part A Jerry Peplinski Project Coordinator, Part B Peplinski Aquaculture N6311 Rods Lane Cecil, WI 54111 715-853-8834 E-mail [email protected] Summary Part B of this project was to take fish hydrolysate prepared in Part A from five different species, compare the assays of the digestate of each species to see which may most closely match the feed requirements of both perch and bluegill. Therefore, hydrolysates from five species (perch, bluegill, bullhead, tilapia, and rough fish) were compared for their macro and micro nutrients, fatty acid lipids and other essential food components. Given the assays of the five species, the task was to match as close as possible the dietary requirements of perch and bluegill (target species). The feed nutritional outline as provided by “Development of Least-Cost Diets for Fishes: An Example with Bluegill” by the Departments of Fisheries & Wildlife Sciences and Animal Sciences, University of Missouri-Columbia, MO. was used as the basis of feed formulation. Feed formulations were completed by Jerome Donohoe of Agricultural Omega Solutions LLC. The requirements for the feed were to develop an approximate 2mm pellet which was extruded so as to provide a slow sinking product. Because the hydrolysates were liquid based with only 15 to 17% dry weight it would take large quantities of product to meet the ingredient requirements.

  • Natural Fertilizers and Their Use in Agriculture
    Natural Fertilizers And Their Use In Agriculture A natural fertilizer is a product which originates from the environment naturally or is derived from products which originate from the environment whereas a mineral fertilizer (or chemical fertilizer) is made by chemical processes in a factory. The term natural fertilizers, as generally used, also includes products that originate from the environment naturally but are further processed in a factory, such as sh emulsion or liquid seaweed. The term natural fertilizer is normally reserved for products which are renewable. We have deliberately excluded mined product such as rock phosphate and potassium nitrate from this list because although they occur naturally the resource is nite and non-renewable. Natural fertilizers are not the same as organic fertilizers. The term organic fertilizers have several dierent meanings and it is often dicult to decide what is meant by the term “organic fertilizer” in any particular situation. The scientic meaning of organic means a substance which contains carbon in the molecule. There is an Australian Standard for Organic farming and this denes both organic produce and allowable inputs into organic production but does not depend on organic certication bodies. The Organic certifying bodies also have their own set of criteria for “allowable inputs for organic farming” a few based on science but others on tradition with little or no scientic basis. Traditionally natural fertilizers have been more expensive than mineral fertilizers however in the last decade or so mineral fertilizers have become much more expensive and natural fertilizers have hardly risen in price. It has also been accepted by government authorities in the last decade or so that inappropriate use of mineral fertilizers severely damages the soil, a fact that scientists have warned about for several decades.

Corresponding author: J. B. Fernandez, [email protected] Abstract. The study was conducted to compare the growth performance of Kappaphycus alvarezii fertilized with two sources of fish waste liquid fertilizers at various concentrations using hanging long-line method for 45 days at Pilaper Island, Masinloc, Zambales. Growth was measured in terms of weight gain (WG) and daily growth rate (DGR). Water parameters were also monitored throughout the experimental period. The fish waste consists of internal organs, gills, scales and fins of milkfish (Chanos chanos) and tilapia (Sarotherodon melanotheron) was obtained from the local market in Pangasinan. Processing of samples into fermented products was done at Chemistry Laboratory of Pangasinan State University- Binmaley Campus. The milkfish and tilapia waste were placed in a separate fermented vat and added with brown sugar and Effective Microorganisms (EMO) at ratio of 1:1. Fish waste was then allowed to ferment for 10 to 15 days. The liquid fertilizers were harvested by sieving it with the aid of fine meshed net. There was significant increase on growth in terms of WG in K. alvarezii within 4-weeks culture period. Increased in WG and DGR was significantly high (p < 0.05) when K.
