Unlocking Content Vocabulary  Estuarine- refers to something related to or characteristic of an estuary, which is the tidal mouth of a large river where the tide meets the stream.  Spawning- refers to the process by which fish, shellfish, and certain other aquatic organisms release eggs and sperm into the water, typically for the purpose of reproduction.  Mimics- things or beings that imitate or copy the appearance, behavior, or characteristics of something else.  Salinity- concentration of dissolved salts, primarily sodium chloride (table salt), in water. It is often expressed in parts per thousand (ppt) or as a percentage  Brackish Water- occurs when the freshwater from a river or lake meets the salty seawater of an ocean body. 4 C. Developing and SUB-TOPIC 1: Phases of Fish Culture Deepening Understanding Fish culture embodies the human effort in raising or maintaining the maximum productivity of all bodies of water, and in maintaining fish supply in order to satisfy human needs. To attain these, fish culture has three different aspects namely: fish cultivation, fish propagation, and fish conservation. Phases or Aspects of Fish Culture: 1. Fish Cultivation- the rearing of fish under controlled or semi- controlled condition. It seeks to produce as high a quantity as possible of graded fish (uniform size) or two to produce the most weight. Classifications of fish cultivation are the following: a. intensive- utilize limited area with very high investment b. extensive- utilize wide area with minimal capital and very low production c. semi-intensive- employ some or the majority of the modern techniques of production. 2. Fish Propagation- the process of increasing fish life either by natural or artificial means of reproduction. This means that fish may be allowed to mature and multiply by themselves. Types of fish propagation: a. natural propagation- fish reproduce naturally in their habitat through spawning, where eggs are fertilized externally or internally b. semi-natural propagation- refers to a breeding approach that involves a combination of natural and artificial methods. In this method, fish are allowed to breed in a controlled environment that mimics their natural habitat to some extent, but with some level of human intervention. c. artificial propagation- this involves human intervention to control the breeding process. It includes methods like stripping eggs and milt (sperm) from fish and then fertilizing the eggs externally. DAY 2 3. Fish Conservation- The scientific means of utilizing fish and other fishery aquatic products/resources. This could be accompanied by observing fishery laws, rules and regulations affecting fishery products. 5 Importance of Fish Conservation Conservation and sustainable management of fish biodiversity are essential for the well-being of both aquatic ecosystems and human societies, supporting ecological integrity, economic development, and the cultural heritage tied to these remarkable aquatic creatures. Local Endangered Species Endangered Species Description Image Whitefin Topeshark A houndshark of the family Triakidae, found only in the tropical waters of the Philippines between latitudes 20° N and 5° N. They inhabit the coastal areas. They can grow up to a length of 96 cm. Adolescent specimens https://www.fishbase.se/Fieldguide/FieldGuideSummary.php have dark areas on their ?genusname=Mustelus&speciesname=mosis&c_code=144 caudal fins Hampala Lompezi Hampala lopezi is a species of ray-finned fish in the family Cyprinidae. It is found only in the Philippines. https://www.sea- ex.com/thailand/angling/hampala-barb.htm Sinarapan The sinarapan or tabyos is a species of fish in the goby subfamily, Gobionellinae, and the only member of the monotypic genus https://www.fishbase.se/photos/ThumbnailsSum Mistichthys. mary.php?ID=25089 6  Sardinella Tawilis Sardinella tawilis is a freshwater sardine found exclusively in the Philippines. It is the only member of the genus Sardinella known to exist entirely in fresh water. Locally, they are known in Filipino as tawilis. https://strawpoll.com/most-delicious-fish- philippines Barbodes Amarus Barbodes amarus, known as the pait locally, was a species of cyprinid fish endemic to Lake Lanao in Mindanao, the Philippines. This species reached a length of 10.8 centimetres. https://fishbase.mnhn.fr/FieldGuide/FieldGuideSu mmary.php?genusname=Barbodes&speciesname=a marus&c_code=608&print=1 Fish Sanctuary Fish sanctuary means to establish and maintain a particular area in the water body as a permanent shelter for protection of fish for natural propagation. Some examples of fish sanctuaries in the Philippines are the following: Popoo (Datag) Marine Sanctuary, Santo Rosario Marine Sanctuary, Ayala/San Ramon Tourist Zone and Marine Reserve etc. Open and End Season Fishing in the Northeast Palawan shall be closed from November to January; the Visayan Sea will be closed from November 15 to February 15; and the Zamboanga Peninsula closes from December 1 until March 1 of every year. – DA BFAR 7  The practice of a “closed season” for fishing is defined by the Philippine Fisheries Code of 1998, as amended in 2015, as “the period during which the taking of specified fishery species by a specified fishing gear is prohibited in a specified area or areas in Philippine waters.” Closed fishing season helps important fish species to reproduce or spawn, fry and juvenile fishes to mature, and fish stocks to recover, the Bureau of Fisheries and Aquatic Resources (BFAR) said in its Fish Files magazine in 2021. DAY 3 Classification of Fish According to their Habitat  Marine or Open Sea Fishes- Marine or sea water fishes are those that primarily inhabit oceans and seas with high salinity levels. Examples are tuna, cod, salmon, flounder, mackerel, sword fish, sardines etc.  Fresh Water Fishes or Inland Fishes- These fish species primarily inhabit rivers, lakes, ponds, and streams with low salinity levels. Examples include trout, bass, catfish, and carp.  Brackish Water Fishes or Estuarine Fish- Estuarine fish live in the transition zone between freshwater and saltwater, such as estuaries and brackish water habitats. Examples include flounder, striped bass, and mullet. 2. Worked Example “Navigating the Waters: Exploring Fish Cultivation, Propagation, and Conservation” Using the Venn Diagram, the students will give the differences and similarities of fish cultivation, propagation and conservation. 8  DAY 4 3.
