Shamu is the performing name for a group of whales known as “killer whales”, Orcinus orca. They are considered the top predator of the ocean whereas their food in nature mostly consist of fishes, squids, seabirds (including penguins), and marine mammals.
The performing “Shamu” was captured in December 1969 near Vancouver Island, Canada and is known to be the oldest captive orca in the world.
The Animal rights group believes that captured animals such as Shamu are desperate and forced to jump, do tricks, splash water and salute the audience and that is why they demand all time to set animals free.

It may be of interest to mention that during the day of the visit, there was a silent protest outside the Sea World by “Animal rights group” calling to set Shamu free.
The photos show phases of the Macrocystis pyrifera production in a specialized laboratory in Chile.
As the organism reaches 10-cm long, they are transferred for grow-out in the open sea, attached with a fine polirope in the base of the plantule to a longline 25-mm diameter – 100 m long. Better results have been achieved in the open sea with the longlines settled in protected áreas compared to those installed in areas exposed to strong waves. The laboratory used in such operation is an insulated container with temperature control of 8 °C. The process begins with obtaining the gametophytes which are cultured in sterile 500-ml bottles, until the sporophytes appear. Then they are transferred to 1-lt bottles and afterwards to 10-lt polycarbonate cylinders. The seawater is enriched with Provasoli media. The water of the cylinders is changed weekly. After the plantules become 5-cm long, they are transferred to 50-lt polycarbonate cylinders, where they are cultured until they become at least 10-cm long, when they are transferred to the sea in expanded polystyrene boxes with humid sponge sheets and gelpack to keep the temperature as low as 8 – 12 °C.
This project has been developed by a group of trainees who participated during 2007 in the Warm Water Fish Production training course which is hosted by the Egyptian International Centre for Agriculture (EICA) in partnership with Japan International Cooperation Agency (JICA). The proposed location of this project is Kigali, Rwanda. The project focus on viable integration system that includes fish (all-male tilapia), ducks and horticulture whereas the advantages of such integration has been highlighted.
This project is one of more group projects which have been supervised by Dr. Abdel Rahman El Gamal.
The production and dispersal of quality fingerlings is a national program of BFAR. The fingerlings are produced by the national and regional centers. The species are mainly tilapia, freshwater prawn, common carp, freshwater catfish and ornamental fish.
The beneficiaries of the dispersal are farmers, researchers, other government agencies, other BFAR regional offices, and LGUs. Dispersal of fingerlings in targeted communal bodies of water is also done yearly to replenish fish stocks due to overfishing.
Stock Now Pay Later Program is a program implemented only in BFAR Region 4A aimed to help the poor fisherfolk/farmers who cannot afford to buy tilapia fingerlings needed for grow-out. Beneficiaries of this program are mostly fish cage and fish pen operators in Laguna de Bay and Taal Lake areas. Payment of the fingerlings is done after harvest.
The picture shows students constructing a fish pond as part of their practical training. It is not a typical sized pond. This was done just to give the students practical skills in pond construction and for in-school practical lessons.
At the moment, hand building fish pond is the common practice in Ghana because of the high cost of mechanical construction. It is large companies and very wealthy people that use the mechanical method of construction.
The most commonly cultured species are Nile tilapia, Oreochromis niloticus and African catfish, Clarias gariepinus. It is not very common to see any other species being cultured. Recently, attempts were made to culture mangrove oysters, but this hasn’t been adopted yet.
Rural aquaculture is encouraged in poor societies to provide a good source of animal protein necessary for fighting child malnutrition as well as for improving the living conditions. Yields obtained in such systems vary between 0.5 and 1.0 lb /m2/year. For the sustainability of this system, technical assistance is provided through a technological transfer/extension system.

The photo shows a modern fish market in Nellore that has been constructed with hygienic conditions. The building was constructed by the National Fisheries Development Board (NFDB), and the Municipal Corporation of Nellore in the city. Establishing a fish market such as this one is a part of enhancing domestic fish consumption programme.
This market accommodates nearly 70 stalls, an equal number of platforms for processing (cutting and cleaning), auction platforms, solid waste, and cold storage facilities. Moreover, there is space for fish drying as well as necessary utilities. It may be of interest to note that the market is furnished with an effluent treatment system.
